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.

ac0b452834 Added '_' prefix to sin and cos. 
Users complained that otherwise the names might clash with their functions.

Removed a "cc65_" prefix. 
This change is needed because of commit 3d8c3a4948.

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

ca2ba14bbe Added option to build samples with statically linked drivers - and have the targets use it by default which don't support dynamically loaded drivers.

7de61e351c Define a standard driver and mode for tgi graphics and use it in the sample 
program. The standard driver and mode is the first one in the tgi_mode_table.

can also be run on apple machines. Changed the makefile to account for the
special start address needed for these programs.
