Thanks, please post when it's up.

An open question I have with OpenGL based UI libraries is how (or if) composting happens. For example, are you rendering an entire window to a frame buffer and then updating that when one of the controls requests changes, or are you just drawing the entire window and controls every frame?

I made a similar UI library which is loosely based on Cocoa but I didn't use any compositing so the entire window needs to redraw itself each frame. This is good enough for basic UI's in games but it's terribly inefficient so I wanted to tackle the problem of a composition layer (frame buffer) which updates only when controls request it and update only that portion of the window.
