Fixes #2465

[tig]

@BDisp and @tznind - I've finally come back to this PR and:

• Merged with v2_develop
• Updated API docs to be more complete and accurate
• Fixed all Views that were using Bounds or calling LayoutSubViews before IsInitalized
• Fixed a few other things (esp in ComboBox) that needed fixing

What I didn't do:

• Actually enforce LayoutStyle as was originally proposed here. I'd love your thoughts on that now.

Please review asap. Thanks!

Something is wrong with All Views Tester. It starting at (0,0) but navigate down and then up the views don't start at (0,0).

Ah, with mouse. With keyboard it's fine. On it...

With the keyboard. Navigate downward until Dialog and then navigate upward and you will see that the views aren't at (0,0) anymore.

Edit:
Dialog is centered horizontal and vertical and thus it seems the upper left coordinate is changed for all views.

Fixed.

Some of the views aren't show, like the TextField.

@BDisp I'd like to merge this so it can be picked up in #3078 and BDisp#172 so I can more easily debug (this PR removes a ton of debug spew).

Are you good with my changes here?

[BDisp]

Done @tig. Thanks.
