Render quads instead of triangles
So apparently, glDrawArrays has a secret undocumented feature that lets you draw
quads. This increases my framerate by 50% on my integrated GPU, so you bet I'm
going to make use of it. On my dedicated GPU there's no significant framerate
difference.
For the record, using EBOs didn't improve performance on the integrated GPU.
