initial blendmode implementation (buggy)
filters
fixes parsing problem in glow/dropshadow-type filters

dropshadow: onTop=0, passes=UB5
glow: onTop=0, passes=UB5
bevel: onTop=UB1, passes=UB4
gradientbevel: onTop=UB1, passes=UB4
gradientglow: onTop=UB1, passes=UB4
fixed typo
initialize filters passed via symbol
re-initialize filters in MC tweens
reset filters array in _initializeFilters
invalidate after setting filters
serialize/deserialize filters
Build script for filters.c
fixes memory leak in filters implementation
simple blendmode implementation
fixes nested masks
fixes blendmodes
colortransforms
clip bounds to viewport
optimized colortransform asm.js filter
alloc less memory
only call alloc/free once
un-asmjs'ed colortransform filter, removed alpha processing (must be done via globalAlpha)
