X11 has four ways to set the cursor:
1. By selecting a glyph from the standard cursor font that is
present on every X installation.
2. By selecting a glyph from any other font
3. By providing a pair of (black & white) bitmaps in the X Bitmap
format, one for the image and one for the transparency mask; and
a pair of colors, one for the foreground and one for the
background. (The files typically have extension .bm or .xbm
and look like a C header file.)
4. With a single image in XPM format. (Files .pm or .xpm,
and also look like C header files.) Note that XPM is a color
format, but cursors under X can only have two colors.
X has no built-in animation of cursors, but I'm sure somebody will
have an OpenSource subroutine for that somewhere.
A single-file format for animated cursors under X does not exist, as
far as I know.
For XPM, see http://www.inria.fr/koala/lehors/xpm.html
