[paragui-users] another devel-opengl update

[Teunis Peters]

There's LOTS of debug code in this one - Any help would definitely be
appreciated.

Anyways, almost solved rendering - fonts will still take a bit.
I just need to trace down all the points that assume that the root surface
has any pixel data...

(SDL_GetVideoSurface()->pixels == NULL in OpenGL)

More later :)

G'day, eh? :)
