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.
With the update to HEAD of the Fuchsia buildtools repo, the new clang
toolchain picked up caused link-time breakage in android x86_64
libFlutter.so builds.

This reverts commit 8ad42f0dae3cb1267c2b9ab99db80e4696ddbc3d.
* Roll Fuchsia buildtools to 85907c59e97527d79bbfdfd849d8e85c24959cc5
This also updates Flutter buildroot to a6e52dbb776c45cc8c57d7143b8eb8b2e762fdfb
which disables -Wtautological-constant-compare temporarily until
https://reviews.llvm.org/D39462 lands in clang. This is in line with
Fuchsia's compiler options.
* Apply clang-format diffs
No logical changes. This applies clang-format from the latest Fuchsia
buildtools to the engine codebase.
* Revert "Revert "Reland "Run Flutter on iOS and Android with color correct Skia" (#3818)" (#3823)"
This reverts commit db8d8a9979901d05b011368226ad5bf61b1da13f.
* 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 cfe70e07d386d6052267fe3772bbd641c8413a54.
* Enable sRGB on IO thread, too
* Add 4444 as a fallback rendering mode
* Use bare ptr to SkColorSpace (not sk_sp) in PrerollContext
The PlatformView superclass constructor was posting a task to the UI thread
that adds the view to the shell's global list. This could result in UI thread
operations seeing PlatformView instances that are not fully constructed and do
not yet have an engine.
This was happening in https://github.com/flutter/flutter/issues/7735
After this patch, platform messages now take the same path through the system
that semantics data does (on Android). Support on iOS will be in another patch.
* Namespaces have been updated to reflect the move from //flutter/sky/shell to //flutter/shell.
* shell/BUILD.gn file has been split into smaller GN files for each subcomponent of the shell (common, GPU, diagnostic, testing).
* GN dependencies have been rewritten to stop exposing common shell dependencies as public. Duplicates have also been removed.
* GPU subcomponent has been updated make it more suitable for Vulkan integration.
* The GLFW backend has been resurrected.
