FocusDraw()

Purpose:

Set up coordinates system and clipping region. Panes rely on their superview to focus them. When a Pane requests focus for drawing, a SubOverlapView sets the clipping region to revealed portion of that Pane's Frame minus the Frames of all sibling Panes that are in front of that Pane. This is an override of FocusDraw() in LPane.
