Sami Liedes 0e65cec6b4 Optimize blend_transformed_tiled_argb(). 
Profiling indicates that this function is one of two hot spots causing
a noticeable latency when changing KDE virtual desktops.

Instead of computing two modulos per pixel in the inner loop, it is
possible to compute the modulos outside the loop and compute a modulo
sum in the inner loop for a reasonable speedup.
