WinForms: Optimize Label by caching the measured size
WinForms: Remove use of TableLayoutPanel from Scrollable
Control.SetParent is now internal, accessed by protected Container.SetParent/RemoveParent methods for implementing containers
WinForms: Fix visual artifacts when adding controls at runtime, and increase performance significantly.  Fixes #116
Wpf: Another pass at to fix some issues sizing controls to a table cell/dock container, using similar structure as winforms with x/yscale propagation, and using MinWidth/MinHeight instead of setting Width/Height.
No longer need to use Suspend/Resume when setting content property - since it's just one line it should do this automatically.
Minor cleanup
Add GTK# 3 to supported list, and Android to under development.
