This reverts commit d807190dd9.
* reverting
* re-reverting
* Fixed every thing but autosize scenarios??
* Fixed hexview
* Fixed contextmenu
* Fixed more minor issues in tests
* Fixed more minor issues in tests
* Debugging Dialog test failure
* Fixed bad Dialog test. Was cleary invalid
* Fixed OnResizeNeeded bug
* Fixed OnResizeNeeded bug
* Fixed UICatalog to not eat exceptions
* Fixed TextView
* Removed Frame overrides
* Made Frame non-virtual
* Fixed radioGroup
* Fixed TabView
* Hcked ScrolLBarView unit tests to pass
* All AutoSize tests pass!
* All tests pass!!!!!!!
* Updated API docs. Cleaned up code.
* Fixed ColorPicker
* Added 'Bounds =' unit tests
* Refactored TextFormatter.Size setting logic
* Cleaned up OnResizeNeeded (api docs and usages)
* Merges in #3019 changes. Makes OnResizeNeeded non-virtual. If we find a use-case where someone wants to override it we can change this back.
* Fixed FileDialog bounds warning
