gEDA-dev: PCB-HID patch - subtle behavior changes

[ldoolitt at recycle.lbl.gov]

For your consideration:

Apply PCB->minSlk even when in a GUI, so people aren't surprised
  at the text linewidths when they make a Gerber

Keep consistent board location on page for all pages of PostScript output

Keep consistent rotation for all pages of PostScript output, after
  conversion to PDF by ps2pdf

Improve accuracy of logic that places drill table
