# PCX file handling
#
# This format was originally used by ZSoft's popular PaintBrush
# program for the IBM PC.  It is also supported by many MS-DOS and
# Windows applications, including the Windows PaintBrush program in
# Windows 3.
#
# history:
# 1995-09-01 fl   Created
# 1996-05-20 fl   Fixed RGB support
# 1997-01-03 fl   Fixed 2-bit and 4-bit support
# 1999-02-03 fl   Fixed 8-bit support (broken in 1.0b1)
# 1999-02-07 fl   Added write support
# 2002-06-09 fl   Made 2-bit and 4-bit support a bit more robust
# 2002-07-30 fl   Seek from to current position, not beginning of file
# 2003-06-03 fl   Extract DPI settings (info["dpi"])
