Patch by Zoltan Herczeg <zherczeg@inf.u-szeged.hu> on 2011-04-28
Reviewed by Nikolas Zimmermann.

This patch contains two sub-routines, one for speeding up
alpha channel only gaussian blur (by 2.5 times) and one
for speeding up all channel blur (by 4 times).

The common code is also redesigned to better fit for platform
specific code. This means large chunks of code was moved to
different files, and all platform specific files are added to
all build systems.
