Stefan, how does the Graal4 GUI work?

[SilentOne1988]

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?
