-- better text size guessing also for FIG
+Parsing and input processing:
 - unify alignment, direction
-- support fonts attributes ?
-- support line thickness ?
-- ~ as overline (grep for ~ in out.fig)
+- find libraries (e.g., from .pro)
+- parse .kicad_wks
+- on parse error, politely complain, don't terminate;
+  convert abort / assert(0) to proper error indications
+
+Data model:
+- implement destructors
+- check for memory leaks

+Visualization (dwg.c and such):
 - 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

+Rendering:
+- better text size guessing also for FIG
+- support fonts attributes ?
+- support line thickness ?
+- ~ as overline (grep for ~ in out.fig)
+- PDF TOC
+- let user set PNG size [we have zoom level]
 - return indication of whether diff found any differences
 - in diff, pass only options understood by cairo_png
 - find out why in Cairo PDF non-dashed lines disappear if CAIRO_LINE_CAP_ROUND
+
+GUI:
+- fonts grow beyond their bounding boxes when zooming in
+- dragging can be slow. maybe reusing old content and only redrawing new
+  will help ?
