 +----------------------------+
 |     How do I use them?     |
 +----------------------------+

 To use any of the sprite routines you load the x-coordinate in a, the
 y-coordinate in e and the address to the sprite in hl. After that you
 do a call to the sprite routine. To display the result you have to copy
 the graphbuf to the LCD. See the examples for further information.


 +---------------+
 |     Notes     |
 +---------------+

 These routines work with 8x8 sprites, but you can use any size you want
 by building larger sprites with two or more 8x8 sprites. Blank pixels
 won't overwrite the background, so you can have 4x3 sprites or 42x33
 sprites etc.


 +-------------------+
 |     Licensing     |
 +-------------------+

 These routines are of course freeware and you may freely distribute them as
 long as all of the files are included and not modified in any way. You may
 also freely use them in your own productions as long as you give me some
 credit.


 +--------------------+
 |     Disclaimer     |
 +--------------------+

 These routines do some pretty lowlevel stuff and could therefore lock
 or reset your TI-83 (they shouldn't though). Make sure you don't have any
 important data on your TI-83, that isn't backed up, before you use any of
 these routines. I take no responsibility for whatever the use of these
 routines may cause to your TI-83.
