Simple repeat: Extend too short source scanlines into temporary buffer

Too short scanlines can cause repeat handling overhead and optimized
pixman composite functions usually process a bunch of pixels in a
single loop iteration it might be beneficial to pre-extend source
scanlines. The temporary buffers will usually reside in cache, so
accessing them should be quite efficient.
