Core (LV::Video) Fix alpha blending of 32-bit videos (#230)

2

This is a rewrite of the buggy 32-bit LV::Video alpha blending code to deal with arithmetic underflows/overflows and the use of an uninitialized register in the MMX implementation (#230). Take...

MMX implementation of LV::Video's blit_overlay_alphasrc() is broken

5

_VideoBlit::blit_overlay_alphasrc_mmx()_ is the SIMD implementation of _VideoBlit::blit_overlay_alphasrc() using x86 MMX instructions. The MMX register `mm6` is used for an unpack but its value is never iniitalized. Could be a confusion...
