[Magic-dev] New contact cut algorithm for magic

[Tim Edwards]

All of you users of Magic who have put up for years with Magic's
implementation of contact cuts will be pleased to know that I've
spent the last week or so implementing an entirely new contact cut
generation algorithm, which will be introduced in version 7.5.159.
The old algorithm was tile-based, and required contacts to be
isolated rectangles.  The new algorithm operates on contact areas of
arbitrary shapes, and can place contact cuts properly into everything
from octagonal pads to intersecting guard rings.  I think everyone
will find this to be a great enhancement to the program.

I could use some beta testers to give the algorithm a good torture
test.
					Thanks,
					Tim
