PCB CAD update

[aiiadict@hotmail.com (Rich J.)]

I got the zoom function to work.

Components can be rotated before and after placing

I can compile the circuits for the logic simulator
to show you what the circuit does.

I got larger than 1 screen graphics to work, so 
board size is unlimited.

Auto trace works, although not perfect.  You
let it connect two points and sometimes need
to edit it manually.

Probably all the work I'll do on it for a while.

I added "silk screen layer" so that you can write
on the board once it's been etched. 

If anyone has the code for the resizeable lasso selector
(as in shapemechanic by beagle bros), I'd like
to take a look...Thinking about disassembling
the BB stuff)
