Pascal Massimino dcbb1ca54a add WebPBlendAlpha() function to blend colors against background ... new option: -blend_alpha 0xrrggbb also: don't force picture.use_argb value for lossless. Instead, delay the YUVA<->ARGB conversion till WebPEncode() is called. This make the blending more accurate when source is ARGB and lossy compression is used (YUVA). This has an effect on cropping/rescaling. E.g. for PNG, these are now done in ARGB colorspace instead of YUV when lossy compression is used.
