I got the INIT and thought it was an interesting concept for a program
that I had thought of doing myself. My main gripe is that is does not
keep track of the pixels that the windows get's dragged over. That is
to say if you should drag your window over your trash icon the trash
icon gets erased and is not redrawn.

Not having the source I cannot comment on how it was written, but I
would have kept an image of the screen in an offscreen buffer and
would not have only updated the dragged window but also the area in
which it was before it was dragged.  While this would cause the update
region to increase in size and thus slow down the "animation" it would
be more aesthetically pleasing.
