According to the docs there is one call to init GLEW which I seem to
have done correctly.  The problem could be that the code is just
asking if the extension is defined, and not if it is supported.  I
think that needs to use a GLEW call to check for that.

I've got the ARB_ shaders going now, but keep hitting the damned 2D vs
RECT problem when using the shaders I wrote for the Mac!  I think the
rectangle extension might work on windows using GLEW though.

I still need to figure out if YUV textures are a reality on the PC or not...
