Thanks for replying so quickly! You are much dedicated, as we can see on the IRC and the mailing list. :) > On Tue, 2010-07-27 at 10:21 -0400, Alexandre Quessy wrote: >> 2) My second requirement, is that we can set the actor (the plane on >> which we draw the texture) can be automatically resized when the >> window is resized.

These will only be in version 1.4: I see. I'll find a way, meanwhile, peeking in the code of those new tools. >> 4) Fourth requirement: be able to use shaders with two textures fed to >> it.

It's nice that the library provides tools to do that.

Yes, there will be plenty of stuff to dig into. Of course, it's always possible to dig and play in the guts of low-level OpenGL stuff.
