Add OpenGL 3.X context creation support

Browse Source 
Matthias Bentrup 2011-10-30 03:58:24 PDT

I've updated the context creation patch to include the bugfixes by Martin
Schreiber and also included a profile bit to request a ES2 compatible profile.

The wgl context creation may use 2 call to wglChoosePixelFormat if no
acceleration attribute is selected, this should work around a bug with buggy
AMD drivers (see #1254).
