Tig d2ad11248f Fixes #3127 - View Layout improvements - Redefines how LayoutStyle works. Fixes AutoSize etc... (#3130)
* Removes CheckAbsoulte and updates unit tests to match

* Fixed code that was dependent on ToString behavior vs. direct test for null

* Dim/Pos != null WIP

* Moved AutoSize specific tests out of Pos/Dim tests

* Broke out AutoSize = false tests to new file

* Commented test TODOs

* New test

* Removed unused API and cleaned up code

* Removed unused API and cleaned up code

* Cleaned up code

* Cleaned up code

* reorg'd Toplevel tests

* Fixed Create and related unit tests

* Added test from #3136

* Removed TopLevel.Create

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

* Removed resharper settings from editorconfig

* Added Pos.Center test to AllViewsTests.cs.
Modernized RadioGroup.
Fixed ProgressBar.
