* Safari font collection tests skip failing methods
* add a clear to the semantics test to make sure no DOM elements are leaking to the other tests
* fix semantics_helper_test. skip for semantics_test. teardown didn't work
* skip test, the skipped method run for 8 minutes according to the logs
* history tests methods runs multiple times. only run them on linux for now. they were also already failing in edge/windows
* making edge default test browser on windows. adding some skips (not all) for methods failing on edge
* skip failing tests. make egde default for testing
* skip one more test
* addressing reviewer comments. removing extra bat file
* Refactor BitmapCanvas. Fix image compositing bug. Allocate canvas lazily
* Fix recording canvas test by restoring context save
* Update recording canvas test for drawColor to show multiply blend
* Introduce `SkiaObject` an object that's backed by Skia C++ objects that need to be explicitly deleted.
* Automatically delete `SkiaObject`s at the end of frame.
* Make `SkPaint` a `SkiaObject`.
Because `SkiaObject`s are deleted at the end of the frame, the object can be reused as many times as necessary within the frame. `SkPaint` in particular is a fairly expensive object. Reusing this object, for example, on `drawRRect` drops the canvas paint time by 30%.
* DRAFT: adding support for enabling semantics on desktop
* Working solution for desktop.
* Refactoring class structure. Removing unrelated comments.
* Fixing enabling semantics from dom_renderer
* Adding unit tests.Fixing failing cases. More refactoring.
* more work on tests.
* Fixing licences
* addressing PR comments
This prevents us from synthesizing an 'add' event if we get a 'move'
event after a 'down' event. This was causing errors because on the
framework side, it will synthesize an 'add' event if it receives a
'down' event, and if you send another 'add' event (e.g. with a 'move'
after a 'down') then it will throw an AssertionError since it already
has received an 'add' event for that pointer.

* WIP on fixing pointer event clicks
* Don't set canvaskit as enabled by default
* Use a Set of pressed buttons rather than a Map of button status to
avoid memory leaks
* Add test for pointer binding
Fix bug where event listeners weren't properly removed
* Interpret negative radii as 0 in recording_canvas drawDRRect
This allows drawing DRRects that may have some negative values on
its corners (caused by deflating a RRect with some non-round corners,
for example)
See added unit test for an example of the above.
