cc65/libsrc/vic20/libref.s
Greg King 410e4502ee Added a 160x192x2 TGI (graphics) driver to the VIC-20 library.
The driver requires a special linker configuration: "vic20-tgi.cfg".
The VIC-20 computer needs at least 8K of expansion RAM!

"tgidemo.c" needed to be adjusted because the VIC-20's vertical (y) range is greater than its horizontal (x) range -- the opposite of most other platforms.  Also, the circle demo would jam on the VIC-20.
