The two important optimizations to be made in gdk-pixbuf/pixops at this point
are:

 A) Special-case compositing/copying with no scaling.

 B) Fix the scaling-down-by-a-large-factor problem.

Especially B). 

Altivec, more MMX, etc, is marginal compared to these, though certainly
more fun to hack on ;-)
