-# GNU LESSER GENERAL PUBLIC LICENSE
-
-Version 3, 29 June 2007
-
-Copyright (C) 2007 Free Software Foundation, Inc.
-<https://fsf.org/>
-
-Everyone is permitted to copy and distribute verbatim copies of this
-license document, but changing it is not allowed.
-
-This version of the GNU Lesser General Public License incorporates the
-terms and conditions of version 3 of the GNU General Public License,
-supplemented by the additional permissions listed below.
-
-## 0. Additional Definitions.
-
-As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the
-GNU General Public License.
-
-"The Library" refers to a covered work governed by this License, other
-than an Application or a Combined Work as defined below.
-
-An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-A "Combined Work" is a work produced by combining or linking an
-Application with the Library. The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-## 1. Exception to Section 3 of the GNU GPL.
-
-You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-## 2. Conveying Modified Versions.
-
-If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
--   a) under this License, provided that you make a good faith effort
-    to ensure that, in the event an Application does not supply the
-    function or data, the facility still operates, and performs
-    whatever part of its purpose remains meaningful, or
--   b) under the GNU GPL, with none of the additional permissions of
-    this License applicable to that copy.
-
-## 3. Object Code Incorporating Material from Library Header Files.
-
-The object code form of an Application may incorporate material from a
-header file that is part of the Library. You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
--   a) Give prominent notice with each copy of the object code that
-    the Library is used in it and that the Library and its use are
-    covered by this License.
--   b) Accompany the object code with a copy of the GNU GPL and this
-    license document.
-
-## 4. Combined Works.
-
-You may convey a Combined Work under terms of your choice that, taken
-together, effectively do not restrict modification of the portions of
-the Library contained in the Combined Work and reverse engineering for
-debugging such modifications, if you also do each of the following:
-
--   a) Give prominent notice with each copy of the Combined Work that
-    the Library is used in it and that the Library and its use are
-    covered by this License.
--   b) Accompany the Combined Work with a copy of the GNU GPL and this
-    license document.
--   c) For a Combined Work that displays copyright notices during
-    execution, include the copyright notice for the Library among
-    these notices, as well as a reference directing the user to the
-    copies of the GNU GPL and this license document.
--   d) Do one of the following:
-    -   0) Convey the Minimal Corresponding Source under the terms of
-        this License, and the Corresponding Application Code in a form
-        suitable for, and under terms that permit, the user to
-        recombine or relink the Application with a modified version of
-        the Linked Version to produce a modified Combined Work, in the
-        manner specified by section 6 of the GNU GPL for conveying
-        Corresponding Source.
-    -   1) Use a suitable shared library mechanism for linking with
-        the Library. A suitable mechanism is one that (a) uses at run
-        time a copy of the Library already present on the user's
-        computer system, and (b) will operate properly with a modified
-        version of the Library that is interface-compatible with the
-        Linked Version.
--   e) Provide Installation Information, but only if you would
-    otherwise be required to provide such information under section 6
-    of the GNU GPL, and only to the extent that such information is
-    necessary to install and execute a modified version of the
-    Combined Work produced by recombining or relinking the Application
-    with a modified version of the Linked Version. (If you use option
-    4d0, the Installation Information must accompany the Minimal
-    Corresponding Source and Corresponding Application Code. If you
-    use option 4d1, you must provide the Installation Information in
-    the manner specified by section 6 of the GNU GPL for conveying
-    Corresponding Source.)
-
-## 5. Combined Libraries.
-
-You may place library facilities that are a work based on the Library
-side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
--   a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities, conveyed under the terms of this License.
--   b) Give prominent notice with the combined library that part of it
-    is a work based on the Library, and explaining where to find the
-    accompanying uncombined form of the same work.
-
-## 6. Revised Versions of the GNU Lesser General Public License.
-
-The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Library
-as you received it specifies that a certain numbered version of the
-GNU Lesser General Public License "or any later version" applies to
-it, you have the option of following the terms and conditions either
-of that published version or of any later version published by the
-Free Software Foundation. If the Library as you received it does not
-specify a version number of the GNU Lesser General Public License, you
-may choose any version of the GNU Lesser General Public License ever
-published by the Free Software Foundation.
-
-If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-## Licensing Intent
-
-The main intention is to make sure forks of the operating system stay open source,
-while external applications can have both open or closed source licenses.
-
-TactilitySDK combines several subprojects and should not have source code with a GPL licenses inside.
-
 ## Past & Present
 
 Formerly, there was a mixed usage of [GPL v3.0](Documentation/LICENSE-GPL-3.0.md) for internal subprojects
 and [Apache License v2.0](Documentation/LICENSE-Apache-2.0.md) for subprojects that would be used in external apps.

-Existing GPL-licensed projects will retain this license, as it cannot be changed to LGPL.
-
-The reason is that LGPL allows for logic in header files, but it comes with limitations (e.g. limit of 10 lines of code in headers).

-## 2. Conveying Modified Versions.
-
-If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
--   a) under this License, provided that you make a good faith effort
-    to ensure that, in the event an Application does not supply the
-    function or data, the facility still operates, and performs
-    whatever part of its purpose remains meaningful, or
--   b) under the GNU GPL, with none of the additional permissions of
-    this License applicable to that copy.
-
-## 3. Object Code Incorporating Material from Library Header Files.
-
-The object code form of an Application may incorporate material from a
-header file that is part of the Library. You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
--   a) Give prominent notice with each copy of the object code that
-    the Library is used in it and that the Library and its use are
-    covered by this License.
--   b) Accompany the object code with a copy of the GNU GPL and this
-    license document.
-
-## 4. Combined Works.
-
-You may convey a Combined Work under terms of your choice that, taken
-together, effectively do not restrict modification of the portions of
-the Library contained in the Combined Work and reverse engineering for
-debugging such modifications, if you also do each of the following:
-
--   a) Give prominent notice with each copy of the Combined Work that
-    the Library is used in it and that the Library and its use are
-    covered by this License.
--   b) Accompany the Combined Work with a copy of the GNU GPL and this
-    license document.
--   c) For a Combined Work that displays copyright notices during
-    execution, include the copyright notice for the Library among
-    these notices, as well as a reference directing the user to the
-    copies of the GNU GPL and this license document.
--   d) Do one of the following:
-    -   0) Convey the Minimal Corresponding Source under the terms of
-        this License, and the Corresponding Application Code in a form
-        suitable for, and under terms that permit, the user to
-        recombine or relink the Application with a modified version of
-        the Linked Version to produce a modified Combined Work, in the
-        manner specified by section 6 of the GNU GPL for conveying
-        Corresponding Source.
-    -   1) Use a suitable shared library mechanism for linking with
-        the Library. A suitable mechanism is one that (a) uses at run
-        time a copy of the Library already present on the user's
-        computer system, and (b) will operate properly with a modified
-        version of the Library that is interface-compatible with the
-        Linked Version.
--   e) Provide Installation Information, but only if you would
-    otherwise be required to provide such information under section 6
-    of the GNU GPL, and only to the extent that such information is
-    necessary to install and execute a modified version of the
-    Combined Work produced by recombining or relinking the Application
-    with a modified version of the Linked Version. (If you use option
-    4d0, the Installation Information must accompany the Minimal
-    Corresponding Source and Corresponding Application Code. If you
-    use option 4d1, you must provide the Installation Information in
-    the manner specified by section 6 of the GNU GPL for conveying
-    Corresponding Source.)
-
-## 5. Combined Libraries.
-
-You may place library facilities that are a work based on the Library
-side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
--   a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities, conveyed under the terms of this License.
--   b) Give prominent notice with the combined library that part of it
-    is a work based on the Library, and explaining where to find the
-    accompanying uncombined form of the same work.
-
-## 6. Revised Versions of the GNU Lesser General Public License.
-
-The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Library
-as you received it specifies that a certain numbered version of the
-GNU Lesser General Public License "or any later version" applies to
-it, you have the option of following the terms and conditions either
-of that published version or of any later version published by the
-Free Software Foundation. If the Library as you received it does not
-specify a version number of the GNU Lesser General Public License, you
-may choose any version of the GNU Lesser General Public License ever
-published by the Free Software Foundation.
-
-If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

+
+You may add Your own copyright statement to Your modifications and may provide

+and grossly negligent acts) or agreed to in writing, shall any Contributor be
+liable to You for damages, including any direct, indirect, special, incidental,

+been advised of the possibility of such damages.
+
+#### 9. Accepting Warranty or Additional Liability
+
+While redistributing the Work or Derivative Works thereof, You may choose to
+offer, and charge a fee for, acceptance of support, warranty, indemnity, or
+other liability obligations and/or rights consistent with this License. However,
+in accepting such obligations, You may act only on Your own behalf and on Your

-with which the Combined Work was made is also called the "Linked
-Version".
-
-The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-## 1. Exception to Section 3 of the GNU GPL.
-
-You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-## 2. Conveying Modified Versions.
-
-If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
--   a) under this License, provided that you make a good faith effort
-    to ensure that, in the event an Application does not supply the
-    function or data, the facility still operates, and performs
-    whatever part of its purpose remains meaningful, or
--   b) under the GNU GPL, with none of the additional permissions of
-    this License applicable to that copy.
-
-## 3. Object Code Incorporating Material from Library Header Files.
-
-The object code form of an Application may incorporate material from a
-header file that is part of the Library. You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
--   a) Give prominent notice with each copy of the object code that
-    the Library is used in it and that the Library and its use are
-    covered by this License.
--   b) Accompany the object code with a copy of the GNU GPL and this
-    license document.
-
-## 4. Combined Works.
-
-You may convey a Combined Work under terms of your choice that, taken
-together, effectively do not restrict modification of the portions of
-the Library contained in the Combined Work and reverse engineering for
-debugging such modifications, if you also do each of the following:
-
--   a) Give prominent notice with each copy of the Combined Work that
-    the Library is used in it and that the Library and its use are
-    covered by this License.
--   b) Accompany the Combined Work with a copy of the GNU GPL and this
-    license document.
--   c) For a Combined Work that displays copyright notices during
-    execution, include the copyright notice for the Library among
-    these notices, as well as a reference directing the user to the
-    copies of the GNU GPL and this license document.
--   d) Do one of the following:
-    -   0) Convey the Minimal Corresponding Source under the terms of
-        this License, and the Corresponding Application Code in a form
-        suitable for, and under terms that permit, the user to
-        recombine or relink the Application with a modified version of
-        the Linked Version to produce a modified Combined Work, in the
-        manner specified by section 6 of the GNU GPL for conveying
-        Corresponding Source.
-    -   1) Use a suitable shared library mechanism for linking with
-        the Library. A suitable mechanism is one that (a) uses at run
-        time a copy of the Library already present on the user's
-        computer system, and (b) will operate properly with a modified
-        version of the Library that is interface-compatible with the
-        Linked Version.
--   e) Provide Installation Information, but only if you would
-    otherwise be required to provide such information under section 6
-    of the GNU GPL, and only to the extent that such information is
-    necessary to install and execute a modified version of the
-    Combined Work produced by recombining or relinking the Application
-    with a modified version of the Linked Version. (If you use option
-    4d0, the Installation Information must accompany the Minimal
-    Corresponding Source and Corresponding Application Code. If you
-    use option 4d1, you must provide the Installation Information in
-    the manner specified by section 6 of the GNU GPL for conveying
-    Corresponding Source.)
-
-## 5. Combined Libraries.
-
-You may place library facilities that are a work based on the Library
-side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
--   a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities, conveyed under the terms of this License.
--   b) Give prominent notice with the combined library that part of it
-    is a work based on the Library, and explaining where to find the
-    accompanying uncombined form of the same work.
-
-## 6. Revised Versions of the GNU Lesser General Public License.
-
-The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Library
-as you received it specifies that a certain numbered version of the
-GNU Lesser General Public License "or any later version" applies to
-it, you have the option of following the terms and conditions either
-of that published version or of any later version published by the
-Free Software Foundation. If the Library as you received it does not
-specify a version number of the GNU Lesser General Public License, you
-may choose any version of the GNU Lesser General Public License ever
-published by the Free Software Foundation.
-
-If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.
