diff dmglexts.h @ 42:3c7e1d3fa5a2
Implement OpengL extension handling through new header file dmglexts.h to
"define" the entrypoints we require and some wonderful preprocessor macro
magic to add checks for them via SDL_GL_ExtensionSupported() and initialize
function pointers with SDL_GL_GetProcAddress().
