This retains gamut correction (adjusting colors for screens with different capabilities), but does all blending and interpolation with sRGB-encoded values. That matches the behavior expected by most users, as well as the behavior of nearly all other systems. It also greatly simplifies the EGL code.
A future Skia change will make this behavior more of a first-class citizen, so some of these implementation details will change again, but the behavior will not. The bulk of this change (elimination of complication from the GL surface code) is permanent - it's just the SkColorSpaceXformCanvas that will be replaced.
* Revert "Revert "Reland "Run Flutter on iOS and Android with color correct Skia" (#3818)" (#3823)"
This reverts commit db8d8a9979.
* Fix test code to match internal API change
* Revert "Revert "Run Flutter on iOS and Android with color correct Skia (#3743)" (#3775)"
This reverts commit cfe70e07d3.
* Enable sRGB on IO thread, too
* Add 4444 as a fallback rendering mode
* Use bare ptr to SkColorSpace (not sk_sp) in PrerollContext
* 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

* Initialize AndroidSurfaceGL and its associated resource context before ANativeWindow acquisition.
This allows us to create the IO thread context way earlier and service load requests on the same. Before this patch, early lifecycle loads would use the default Skia texture loader instead of the Async texture loader we provide.
Fixes https://github.com/flutter/flutter/issues/6581
* Don't destroy surface_gl_ PlatformViewAndroid::ReleaseSurface.
