Keeps current API as-is by defaulting to the new BorderAuto BorderStyle
which keeps the default borders on Windows and defaults on none on Frames.
Allows setting a Window Border to BorderNone for a frameless Window.
Need to allow setting the border default in the Window Manager to avoid
the border from being drawn and then removed.

This patch introduce internal changes in order to #1 actually clip
content avoid growing parent's size and keeping controls with their
own pre-set sizes and also #2 add a scrollable feature to frame control.
