Max Horn b6f85de558 instead of using a stack array, use regular variables (marked with the register keyword to hint the optimizer) for the color data. At least over here this helps the optimizer *A LOT* - instead of keeping w[] on the stack, on the PowerPC all values stay in registers, for a nice speed boost. Shouldn't hurt x86 either ...

2xsai.cpp

templatized more of the scalers; also introduced template struct ColorMasks (shortens/simplifies other code a bit)

intern.h

synced hq2x with upstream changes; some performance tweaks to hq2x/hq3x (I think for bigger speed improvement we'd have to use ASM (with C++ fallback of course)...
