- TODO:
- - hook up remaining unimplemented extensions
- - research what guarantees glXWaitX, glXWaitGL are supposed to offer, and implement then
- using GdiFlush and/or glFinish
- - pbuffer clobbering: we don't get async notification, but can we arrange to emit the
- event when we notice it's been clobbered? at the very least, check if it's been clobbered
- before using it?
- - are the __GLXConfig * we get handed back ones we are made (so we can extend the structure
- with privates?) Or are they created inside the GLX core as well?
-*/
-
-/*
- MSDN clarifications:
-
- It says SetPixelFormat()'s PIXELFORMATDESCRIPTOR pointer argument has no effect
- except on metafiles, this seems to mean that as it's ok to supply NULL if the DC
- is not for a metafile
-
- wglMakeCurrent ignores the hdc if hglrc is NULL, so wglMakeCurrent(NULL, NULL)
- is used to make no context current
