#2 Docking hint can overlap

[Peer Sommerlund]

Revision 132 from trunk/demo

Dragging a window shows 4 docking hints at the frame
edges and a hint cross inside the window below the
cursor. If the window below the cursor is small and
located near the edge-docking hint, the cross-hint will
overlap the edge-docking hint.
