Re-add GraphicsPath.GetRoundRect
Wpf/Gtk: GraphicsPath.Transform should append the transform, not overwrite it
Gtk: Fix NRE with GraphicsPath.Clone()
Wpf: Implement ImageView.BackgroundColor
Implement Graphics.ClipBounds/SetClip(RectangleF)/SetClip(IClippingPath)/ResetClip for all platforms
Implement Graphics.Clear for all platforms
Added tests for clipping/clear
Cleanup
GraphicsPath.Transform should prepend the matrices, not append
WinForms: No need to check for nulls for EtoDrawable.OnPaint, should never be null.
Implement Size constructor to convert SizeF to Size (alternative to Size.Truncate)
Cleanup
