/** \file
* \ingroup glew-mx
*
* 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.
