* 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

Eliminates logging to stdout on Android -- now using __android_log_print
only.
Eliminates logging to syslog on iOS -- now writing to stdout with the
existing ASL redirection (from platform_mac.mm) only. syslog() wasn't
ever picked up in logs.
This patch is a pre-factoring change before swapping out iOS engine
logging to a flutter-specific mechanism.
**This is a breaking change on iOS**
Previously, the `paused` state was entered when the application resigned
active status. `inactive` now maps to this status. `paused` now maps to
an app that has been backgrounded.
`inactive` is currently emitted on iOS only and corresponds to iOS's
foreground inactive state.
Current state transitions are:
`resumed` <--> `inactive` <--> `paused`
suspending is currently emitted on Android only and corresponds to the
transition to Android's stopped state.
Current state transitions are:
`resumed` <--> `paused` --> `suspending` --> `resumed`
These transitions may change in future.
Previously, it was a static. Doesn't have much effect in practice because we
only use this microtask queue for main isolates, which exist on a single
thread.
* Remove the Point class.
* Add Size.contains and Rect.translate for consistency
* Make Offset and Size compare == with subclasses.
Without this we would break the _DebugSize hack.
* Fix copy/pasta
* Fix the examples in the engine repo
