***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
* Perform all iOS logging through ASL
As of iOS 10, ASL is deprecated and replaced with os_log. ASL calls
continue to result in logging but as of iOS 10.3, only ASL_LOG_NOTICE
level and above are logged.
This change partially reverts 2937f06a15cecf5e9398334617ca156316dae52b,
adding back stdout and stderr redirection, which resulted in loss of
some direct writes to stdout that were necessary for debugging.
This change replaces the direct use of syslog with ASL on iOS, which
Apple has stated will continue to log on iOS >= 10. This eliminates the
need for the previous fwd-declaration of syslog.
