[QuickTacBeta] Tiger Cub support

[David Farmer]

I just started trying the bate of 4.0, using a Tiger Cub to emboss.  The Braille dots are "shadowed" with lower dots around the main dots, which makes the braille almost completely unreadable, visually or, I suspect, tactilely.  Instead of four dots for a "g", there is a small, solid square.  

Also, the software would be much easier to use for me, as a Geometry teacher, if I could force shapes to be regular by holding the shift key as I drag.  Most graphics programs have this, and I miss being able to easily produce perfect squares, equilateral triangles, etc.
