This is the second patch for xpgs-2.5. It is independent of patch1 - so you
can apply these in any order.

There are numerous bug fixes, some speedups/optimizations, documentation
updates, and new functions and methods. The changes are detailed in
README.new.

The next version will be 2.7 (no 2.6 :-) in at least a couple of months time.
No guarantees, though.

To apply, use "patch -p1 <xpgs.patch2"

----------about xpgs-2.5--------------
This is xpgs 2.5 - a suite of programs to design, generate and animate
Single-Image Random Dots Stereograms (SIRDS) for the X Window System, and
output Single-Image Stereograms (SIS) or autostereograms in a variety of
formats.

There have been a deluge of dotty poster on sale in your high street shops
(or shopping malls). This is a 'freeware' distribution that produces such
images and is written to run using X11R6/5/4 (or even X11R3) graphics on any
computer with an ANSI C compiler and Xlib.

Distribution

Further information and resources:
==================================
  The main SIRDS archive is katz (address above), this holds lots of
  pictures, programs, the alt.3d SIRDS FAQ and a paper on SIRDS.

  Also, with popularity of the WWW, there are now many SIRDS web pages. The
  pages maintained by the author are at
     http://h2.ph.man.ac.uk/gareth/sirds.html
  which holds a copy of the FAQ, a gallery of SIRDS and SIS produced using
  programs written by Gareth Richards (responsible for SIRDSAni for PCs) and
  me (xpgs), a short article on autostereograms (including an explanation of
  the algorithms for making SIRDS) and many links to other SIRDS pages
  throughout the world.

IMPORTANT NOTICE
================
  Any feedback, reactions, suggestions, hacks, contributions, constructive
  criticisms, donations of large amounts of money, etc. would be most
  welcomed.
