** NOTES **
-- PutImage: the following are supported: COPY_PUT, OR_PUT, XOR_PUT, AND_PUT
NOT_PUT does not do a NOT!
NOT_PUT has been changed to do a modified COPY_PUT. It will
copy all the bits in an image that are not 0 (zero). Bits that
are zero will not be written to the screen. This facilitates
displaying an image, say of a ball, and not having to worry
about the corners of the putimage box.
Typically you would have to use NOT_PUT to create a bit mask
of the bits not to effect on the screen. Let us know if you
like this method of circumventing extra calls to getimage and
putimage.

-- Mode 3 (360x480) trash:
You may notice some horizontal trash or noise in this mode on
certain VGA cards, most notably the video 7 vram card. Video
7 provides a utility called: V7VGA.COM that will set the vga
card into "PURE" mode. This forces that card to register
compatable VGA mode and will remove the trash.
