* remove new test platform dispatchers
* Amend documentation
* Fix crash when widgetspan does not produce a semantics node in render paragraph
* fix comments
* fixed corner case, added test, refactored semantics widget
* addressing comment
This allows us to rationalize the nullability of some of our APIs.
Prior to this we'd end up in a situation where Container assumed that
getClipPath would be non-null but Decoration was ok with return null.
* Redesigns the interface between MouseTracker and RendererBinding&RenderView.
* Simplifies the structure of RenderMouseRegion.
* Extracts the common utility code between mouse_tracker_test and mouse_tracker_cursor_test.
* Add clipBehavior to RenderFlex
* Add clipBehavior to FittedBox
* Add clipBehavior to Flex and FittedBox
* Add clipBehavior to UnconstrainedBox
* Add clipBehavior to Stack and Wrap
* Add clipBehavior to TextEditable
* Add clipBehavior to ListWheelScrollView
* Add clipBehavior to SingleChildScrollView
* Add clipBehavior to RenderViewportBase's widgets
Those widgets are NestedScrollView and ShrinkWrappingViewport.
* Fix tests
* Remove enum Overflow and fix typo
* Remove clipToSize
* Analyze fix
* Remove Mixin and other small fixes
* Fix tests and respect Stack's default clipBehavior
* Add Overflow back to make it non-breaking
* Restore clipBehavior to make it non-breaking
* Small fixes
* Fix rebase
* Uses a special cursor value MouseCursor.defer to mark deferring. MouseTrackerAnnotation.cursor is now non-null. The mouseCursor argument of widgets or render objects can be null, which indicates using the default value.
* Moves SystemMouseCursors.uncontrolled to MouseCursor.uncontrolled.
* Changes how MouseCursor.debugDescription is defined. Previously MouseCursor.toString returns $runtimeType($debugDescription), while now it returns $debugDescription. Implementations of classes are updated, except for the ones of MouseCursor.defer and MouseCursor.uncontrolled are simply "defer" and "uncontrolled".
