Improving Postscript output (on-going)

- postscript.c: added page layout parameters and header
- postscript.c: increase initial size for maxfont from 100 to 1000, so that we 
  don't end up with zero-sized fonts for zoom = 1
- postscript.c: desired size of measurement text is no longer affected by zoom
- postscript.c: roughly doubled size of measurement text
- postscript.c: adjust zoom to package dimension and try to draw 2x and 1x 
  package next to enlarged package

Major missing features:
- populate input area (still needed: mm/mil, rezoom)
- add postscript output (partially done)
- add option to include/omit helper vecs and frames (done for display, still
need postscript). Better idea: in PS, print the component 10x, 1x, and then
@ -10,11 +9,12 @@ Minor missing features:
- reorder rows in a table (can use text editor)
- reorder columns in a table
- reorder variables in a frame (can use text editor)
- move items/vectors up and down the hierarchy
Error detection:
- eliminate duplicate instances
Style:
Style and usability:
- make column of entry field greedily consume all unallocated space
- make menu bar consume all unallocated space instead of sharing it evenly with
upper toolbar
@ -26,6 +26,8 @@ Style:
don't properly size rotated text.
- when changing the part, we should automatically switch to a configuration
that generates any of its (non-global) elements
- add zoom controls to top toolbar
- add tooltips
Bugs:
- default silk width has no business being hard-coded in obj.c
