If the recalcBBoxes argument is false, a number of things will *not*
be recalculated upon save/compile:
1) glyph bounding boxes
2) maxp font bounding box
3) hhea min/max values
1) 'glyf' glyph bounding boxes
2) 'CFF ' font bounding box
3) 'head' font bounding box
4) 'hhea' min/max values
5) 'vhea' min/max values
(1) is needed for certain kinds of CJK fonts (ask Werner Lemberg ;-).
Additionally, upon importing an TTX file, this option cause glyphs
to be compiled right away. This should reduce memory consumption
