source: vbox/trunk/src/VBox/Additions/x11/x11include/mesa-7.2/GL/glx.h@ 68495

Last change on this file since 68495 was 64269, checked in by vboxsync, 8 years ago

bugref:3810: X11 Guest Additions maintenance: remove unnecessary parts of the Mesa 7.2 sources from the tree, leaving only public OpenGL header files. The reason we are not just switching to using the Mesa 11 headers is that they currently conflict with our API definitions in APIspec.txt including due to increased const-correctness.
