* Revert "Revert "Set SkPath::setIsVolatile based on whether the path survives at least two frames (#22620)" (#23044)"
This reverts commit feda80cb42f99e2588a9a6b9ab3dd1f812d0f45b.
* Fix tracing
This enables delayed event delivery for macOS, so that shortcuts can handle keys that are headed for a text field and intercept them. This fixes the problem where pressing TAB (or other shortcuts) in a text field also inserts a tab character into the text field.
The other linux shell (and all the other embedding) have support for
getting the locales from the system and sending them over the
flutter/localization channel. The glfw shell does not have that which is
causing a crash on an assert now that Locale is no longer nullable
in Platform.
This adds a similar approach to what is going on over in the other linux
shell.
Sends the flutter/settings update message to the engine after starting
it. For now values other than 24-hour time preference are hard-coded,
but dark mode support can be added later.
Fixes https://github.com/flutter/flutter/issues/65590
Fixes a precision bug was introduced in 5f363dc, which improved the
precision of lerpDouble when the extrema differed significantly in
magnitude.
_lerpInt doesn't have this issue since the extrema are passed as 64-bit
twos-complement values, therefore the difference will always be accurate
so long as it doesn't overflow. This reverts the _lerpInt implementation
to the original a + (b - a) * t, but adds a test to avoid a regression
if anyone is tempted to make it consistent with the others.
This re-lands #20496 and #21780 after fixing the semantics-enabling code that was causing the post-submit web_smoke_test to fail.
Below is the description from the original PR:
This is a PR for converting the dart:ui code in the engine to use a multi-window API. The goal here is to convert from the window singleton to an API that has the concept of multiple windows. Also, I'm matching up the new PlatformDispatcher class to talk directly to the PlatformConfiguration class in the engine. I'm not attempting to actually enable creating multiple windows here, just migrate to an API that has a concept of multiple windows. The multi-window API in this PR currently only ever creates one window.
The design doc for this change is here.
The major changes in this PR:
Move the platfom-specific attributes out of Window, and into the new PlatformDispatcher class that holds all of the platform state, so that the platform code need only update the configuration on this class.
Create FlutterView, FlutterWindow, and SingletonFlutterWindow classes to separate out the concepts of a view (of which there may be multiple in a window), a window (of which there may be multiple on a screen, and they host views), and a window where there is only ever expected to be one (this hosts the entire API of the former Window class, and will eventually be the type of the window singleton).
Next step after this PR lands:
Remove the Window class entirely (it is replaced by SingletonFlutterWindow). Some minor changes in the Framework are needed to switch to using SingletonFlutterWindow directly first.
The Window class still exists in this PR, but will be removed as soon as the framework is converted to point to the SingletonFlutterWindow class instead. They share the same API, just have different names (Window is currently a subclass of SingletonFlutterWindow). The intention is that the Window name will be freed up to use as a widget class name in the framework for managing windows. The singleton called window will remain, and keep the same API it has now.
