New GDK port: OpenGL

[Derek Simkowiak <dereks realloc net>]

    Hello,
	I've written an OpenGL game engine that uses SDL for its input (it
uses Quake2 BSPs for levels).  Now I need a widget library to build a GUI
for my game.  I want the GUI to float above the 3D-rendered world,
possibly with some alpha translucency.

	If I understand correctly, I can port GDK to OpenGL (and an input
and framebuffer library, such as SDL, glX, svgalib, or GLUT) and then GTK+
will render to an OpenGL window.  I'll probably need to add some basic
windowing code, like the framebuffer port.

	This will produce something similar to GLUI, see:

http://www.cs.unc.edu/~rademach/glui/

	I'd use GLUI, but it depends on GLUT and is missing some key
widgets.  It seems like it'd be easier and more fruitful to port GDK to
OpenGL+SDL than port GLUI to SDL and write some all-new widgets. 

	I have some questions:

1. Is this plausible?
2. Are there any caveats I should be aware of?
3. What kind of timeframe should be expected?  Can this be done in 40
hours?
4. What version tree should I start with?  The latest CVS...?
5. Who did the framebuffer port?  I'd like to ask them some questions
about their porting effort, and their windowing code.


Thank You,
Derek Simkowiak
