2001-10-18 David Turner <david@freetype.org>
* src/psnames/pstables.h, src/tools/glnames.py: rewrote the "glnames.py"
script used to generate the "pstables.h" header file. The old one
contained a bug (yes !!) that made FreeType return incorrect glyph
names for certain glyphs..
* src/truetype/ttdriver.c: changing computation of pixel size from
character size to use rounding. This is an experiment to see if this
gives values similar to Windows for scaled ascent/descent/etc..
