    Which seems handy for cross-developing for Android, etc.

    Regal.h can be used with REGAL_NO_ENUM=1, REGAL_NO_TYPEDEF=1 and REGAL_NO_DECLARATION=1 to limit things to the typedefs.

    Use glewinfo

    I'd suggest running the glew tool bundled with GLEW to see what OpenGL is reporting in terms of GPU, available extensions and GL version.

    Times have changed. I want to stream pixels from my hefty uber-SLI multi core desktop to my iPad. Why should I need to haggle with the server GUI (if any) for that?
