eda-tools/sch2fig/TODO

- better text size guessing also for FIG
- unify alignment, direction
- support fonts attributes ?
- support line thickness ?
- ~ as overline (grep for ~ in out.fig)
- glabel: build for "right" style, then rotate poly (like hlabel)
- show open pins / wires
- check remaining alignment / direction / rotation cases in switch statements
- support mirroring (and detect-complain if unexpected) [should be done now]
- pin shapes (inverted, clock, etc.)
- optionally display pin type
- find libraries (e.g., from .pro)
- PDF TOC
- let user set PNG size or zoom level
- parse .kicad_wks
- on parse error, politely complain, don't terminate;
  convert abort / assert(0) to proper error indications
- implement destructors
- check for memory leaks
- record.c (bb_rot): implement bounding boxes for text
- nesting gfx in diff is a huge kludge, caused by global vars in gfx.c
- move path name guessing into file.c
- return indication of whether diff found any differences
- in diff, pass only options understood by cairo_png
