// ogl.cpp importExtensionFunctions).
// (TODO: I think this is meant to be context-independent, i.e. it
// doesn't matter that we're getting extensions from SDL-initialised
// GL stuff instead of from the wxWidgets-initialised GL stuff, but that
// should be checked.)
// So, make sure it's loaded:
