A DESCRIPTION OF THE PROBLEM :
when using the JDesktopPane optimized outline drag mode,
moving a JInternalFrame near the boundaries (say, the lower
right corner) results in bad mojo. the frame almost looks
like it is doing the normal drag mode and its paint gets
smeared all across the desktop background. will send .png,
.java on request. will try to look into it before going to
school tomorrow. do believe it used to work in 131


REGRESSION. Last worked in version 1.3.1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. build JDesktopPane with
setDragMode(JDesktopPane.OUTLINE_DRAG_MODE)
2. build a JInternalFrame with some content (necessary?)
3. move JInternalFrame close to a boundary. let simmer for
a few seconds.
4. now try to move frame towards boundary. should make a
big mess.

EXPECTED VERSUS ACTUAL BEHAVIOR :
expect clean window moving. instead get big mess.

This bug can be reproduced always.
