[AD] POT hack for OpenGL driver

[Peter Wang <novalazy@xxxxxxxxxx>]

Hi,

Here is a hacky patch to make the OpenGL driver round up textures to the
next power of two.  Actually it does it unconditionally.  I ran into
some trouble checking extensions because they weren't necessarily
available when I wanted to check them.  Anyway, maybe someone who
understands the graphics code can do something with it.

Sorry about mixing in some formatting changes.

Peter
