Embedding Graphics.

Well, my method doesn't use any compression, but it seems to work for
what I designed it for.  And it's simple.
I make a directory for the icons I want to use in my program, put all my
icon bmp files in it, put this program in the directory and run it.  It
creates a file called Icons.e that defines a global sequence of icons.  Then
if for example, all of my icons have a bright white background and I want to
change it to light gray, all I have to do is open the include file in a text
editor and use it's search function to replace all occurrences of 15 with 7.
All of the icons are changed.
     To use an icon, I can just say display_image( {x, y}, icon[UPARROW] )
or whatever.  (constants for icons are named after their bmp file name)
     Of course, I suppose everyone's already done this.  But thought I might
as well share anyway.
