PaintBrush: Make the line, rectangle and ellipsis preview work again

You can now see what you're drawing before committing to it. This works
by passing the second_paint_event from the ImageEditor to the tool.
We also pass the active layer which makes it easier for the tool to
keep his logic in layer-relative coordinates even while drawing preview
states directly into the ImageEditor backing bitmap.
