2001-10-17 David Turner >david@freetype.org>
Tagging files with VER-2-0-5 for upcoming 2.0.5 release
Testing new CVS-mail script (thanks Just !)
* include/freetype/freetype.h, include/internal/ftobjs.h,
src/base/ftobjs.c, src/sfnt/sfdriver.c, type1/t1driver.c,
cid/cidriver.c: Adding a new function named 'FT_Get_Postscript_Name' to
retrieve the Postscript name of a given font. Should work with all
formats except pure CFF/CEF fonts (this will be added soon).
