Made tgidemo draw circles in blue instead of orange.
...
That change lets it be built on two more platforms (Atmos, Telestrat).

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.

8b5ae001e5
Refactored the TGI demo.
...
Cleared the screen at the beginning of each demo instead of at the end. Setting the colors before clearing makes it more reliable and consistent across platforms.

Added '_' prefix to sin and cos.
...
Users complained that otherwise the names might clash with their functions.

e235ac2a0e
Added a preprocessor guard to tgidemo.c that avoids a compiler warning.
...
DoWarning() is compiled only if it will be used.

Added option to build samples with statically linked drivers - and have the targets use it by default which don't support dynamically loaded drivers.
