Not too sure on the fancy graphics stuff, but I can recommend a book or two:

     TITLE:       Programmer's Guide to the EGA/VGA *
     AUTHOR:      George Sutty and Steve Blair
     PUBLISHER:   Brady Books / Simon and Schuster, Inc.
     DATE:        1988

     TITLE:       Programmer's Guide to IBM PC and PS/2 Video Systems
     AUTHOR:      Richard Wilton
     PUBLISHER:   MicroSoft Press
     DATE:        1987

     TITLE:       Programmer's Guide to the EGA and VGA Cards
     AUTHOR:      Richard F. Ferraro
     PUBLISHER:   Addison - Wesley Publishing Co.
     DATE:        July, 1988

Sorry no ISBN info, but these come straight out of the file
proginfo.doc which came with my ATI SVGA card.  I'm familiar with the
last two; I have Wilton's book and it looks like it has excellent
coverage of basic graphics techniques (lines, circles, fills), but I
haven't done anything with these, and I don't know about that fancier
stuff you wanted.  Ferraro's book is mostly excellent for
card-specific techie stuff -- so you want to know what bit of what
register does what, and when?  This'll tell ya.  I included the first
one because ATI recommends it.  (Hence the * next to it.)

As for GIF's -- there is a fairly helpful file out there on the GIF
format.  Check the msdos/gif directory of your friendly neighbourhood
SIMTEL mirror site.
