Description

[Andreas Gal :gal]

We currently use GL_REPEAT for layer textures because it permits us to save draw calls for rotated buffers. However, on average we have less than 2 quads for a rotated buffer (since in most cases buffers are not rotated at all, and the next most common case is scrolling in one direction only). If we stop using GL_REPEAT we need multiple draw calls (much fewer than 2 on average). In return we save the VBO setup though, and we are about to remove buffer rotation anyway.
