Use a shorter/simpler license convention, stops the header taking so much space. Follow the SPDX license specification: https://spdx.org/licenses - C/C++/objc/objc++ - Python - Shell Scripts - CMake, GNUmakefile While most of the source tree has been included - `./extern/` was left out. - `./intern/cycles` & `./intern/atomic` are also excluded because they use different header conventions. doc/license/SPDX-license-identifiers.txt has been added to list SPDX all used identifiers. See P2788 for the script that automated these edits. Reviewed By: brecht, mont29, sergey Ref D14069

|
|
*
|
|
* Support for GLEW Multiple rendering conteXts (MX)
|
|
* Maintained as a Blender Library.
|
|
*
|
|
* Different rendering contexts may have different entry points
|
|
* to extension functions of the same name. So it can cause
|
|
* problems if, for example, a second context uses a pointer to
|
|
* say, glActiveTextureARB, that was queried from the first context.
|
|
*
|
|
* GLEW has basic support for multiple contexts by enabling WITH_GLEW_MX,
|
|
* but it does not provide a full implementation. This is because
|
|
* there are too many questions about thread safety and memory
|
|
* allocation that are up to the user of GLEW.
|
|
*
|
|
* This implementation is very basic and isn't thread safe.
|
|
* For a single context the overhead should be
|
|
* no more than using GLEW without WITH_GLEW_MX enabled.
