Stefan, how does the Graal4 GUI work?
 

I'm making my own GUI system (not in gscript, C++ and OpenGL), and I was wondering how your GUI works. The way i've chosen to do it is to tile a bunch of pieces, like I have a bunch of 4x4 pixel images that make up parts of the gui, and i'll make a bunch of little quads and draw the pieces on them. I was afraid it may cause some performance loss though, due to so many tris that make up the quads. Any recommendations or suggestions?

Stretching or vertex buffer?
This is not really a v4/Graal related post though, sorry
