de6050f21d Added a tgi_arc function. Removed the old ellipse code and create a new 
ellipse module that calls tgi_arc.

78070d8bfb Added tgi_circle and tgi_ellipse functions. The latter works, but could be 
optimized.

7c804513fa The upper 16 bit differ between signed and unsigned multiplication, so while 
for 16x16=16, the unsigned routine can be used, regardless of signedness, this
is not true for 16x16=32.

1bec071755 - Replaced font .byte's with font .incbin file

- Modified font using Beagle Bros Shape Mechanic font editor to look like Apple2 text mode glyphs (with the exception of '_' because OUTTEXT _always_ inserts 2 empty pixels between chars)

c65925b0b9 Merged the sine/cosine routines into one file, because they're often used 
together, we save some code in this case, and the sine table isn't of real use
for programs, because it contains some specialities.
