* Run Flutter on iOS and Android with color correct Skia (#3716) ***Turns on color correct rendering for Android and iOS ***Communicates dst color space to raster cache ***Turns on color space aware image decoding Test: ***color_testing_demo on Pixel XL ***flutter_gallery on iPad Mini and iPad Pro (haven't figured out how to run manual_tests on iOS) TODO: I needed to split up this CL somewhere. These are follow-up tasks. ***Make desktop backends color correct ***Make debugging tools (ex: encoding frames to png) preserve color space ***Investigate using UIKit API to allow iOS to fine tune color space of rendered content
