Make width/height optional when copying an image into a Bitmap
Wpf: ColorDialog should fire ColorChanged event after the user selects a color
Wpf: Should use Padding instead of Margin for DockLayout for certain cases (dock within dock)
Mac: do not dispose graphics (causes major slowdown)
Wpf: use interpolation when scaling a bitmap
Wpf: Upgrade WpfToolkit
Wpf: Greatly simplify and optimize Drawable using tiles - can now change whether to use tiling and the tile size via the handler using styles. All tile logic is now done in Drawable instead of using a VirtualCanvas which was extremely slow when resizing the canvas.
Wpf: MouseUp/Down should report which mouse button was changed, not the current state of the buttons
Wpf: Handle controls that want to trap single AND double click events properly
Wpf: MouseDown should capture the mouse (like other platforms)
Wpf: Clone brush/pen when drawing so that changing them after the draw/fill operation does not change what is rendered
Wpf: Manually position dialog as WindowStartupLocation.CenterOwner does not always work correctly for auto-sized forms
Wpf: IndexedBitmap should allow palette to be set when locked, and also be used in background threads
Add Padding operator +/- to add/subtract values
Wpf: Use layout rounding for each window so that controls are aligned to pixel boundaries correctly (fixes artifacts between Drawable tiles)
Wpf: Open/Save File Dialog should use the local path for the initial directory
Properly set focus on a control when Focus() is called before it is loaded
Cleanup
