Denys Smirnov	20447e9ec9	Fix alpha in PorterDuffImageComposite. (#3411) ... There were two bugs in PorterDuffImageComposite. The first one is the fact that it uses the mask input directly as alpha, missing the conversion (`1-a`). The fix is similar to c16f5744. The second one is that all color composition formulas assume alpha premultiplied values, while the input is not premultiplied. This change fixes both of these issue.	2024-06-04 16:37:11 -04:00
