Programmer's perspective: wmfishtime
------------------------------------

This is a pretty clean implementation of a sprite based graphics engine for
dockapps, or any other flat surface, for that matter.  Current version allows
drawing colormap-based sprites directly to backbuffer or alpha-blended on top
of backbuffer.  There is some limited support to drawing colormap based
text strings, with some character set limitations. There is a routine for
drawing anti-aliased colored lines, of variable width.

There are a couple things implemented inside fishmon.c that are not enabled,
one of them is wobbling weed on the bottom part of the screen, and another is
a thermometer "gauge", which I couldn't find any use for in this version.
Originally this project started as a hack-in-progress of the graphics engine,
so turning it into a clock dockapp wasn't really planned.

All the code related to calculating clock hand positions came directly from
wmtime-1.02beta - I am terrible at calculating this kind of math, and really
have no idea how to do it. :)

Antialiased line algorithm came from some random java program, and uses
bresenham line drawing algorithm with a little anti-aliasing addon.  This
results in very sexy looking lines, perfectly blended with the underlying
background - much better than the method used by wmtime, which made their
"antialiased" clock hands look kind of jaggy.

The code is pretty well optimized, it tries not to do anything more than it
needs to be done, caching stuff that's hard to calculate and only recalculating
when necessary.  Due to the dynamic nature of physical simulation involved,
screen is updated at approximately 33 frames per second.

gimp/ directory contains the original sprite image, which can be modified and
saved as indexed .h file from gimp.  However before you go modifying the sprite
image make sure and understand how it works :)  There are a couple of unused
sprite indexes, and more can be added if necessary...
