ofxsTransform3x3: better motion blur defaults
Invert: put channel selection on one line
Merge branch 'master' of https://github.com/devernay/openfx-misc
Merge: use ofxMaskMixPix & handle missing A correctly
- ofxsMaskMixPix should be preferred for per-pixel effects (no geometric transform)
- any missing image/pixel should be considered as black and transparent (see everywhere in the OFX spec)
- just implement a shortcut in case both are missing
ofxsMaskMixPix: clarify implementation
- use ofxsClampIfInt
- mask/mix even if srcPix is NULL: it is considered as black and transparent
ofxsMaskMix: factorize! use ofxsMaskMixPix
