# The Python Imaging Library.
# $Id$
#
# PIL raster font management
#
# History:
# 1996-08-07 fl   created (experimental)
# 1997-08-25 fl   minor adjustments to handle fonts from pilfont 0.3
# 1999-02-06 fl   rewrote most font management stuff in C
# 1999-03-17 fl   take pth files into account in load_path (from Richard Jones)
# 2001-02-17 fl   added freetype support
# 2001-05-09 fl   added TransposedFont wrapper class
# 2002-03-04 fl   make sure we have a "L" or "1" font
# 2002-12-04 fl   skip non-directory entries in the system path
# 2003-04-29 fl   add embedded default font
# 2003-09-27 fl   added support for truetype charmap encodings
#
# Todo:
# Adapt to PILFONT2 format (16-bit fonts, compressed, single file)
