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.

50c1db0331 Changes to the TGI driver API: 
* Removed CIRCLE
  * Aspect ratio is a new header variable
  * Removed the reserved bytes - it's easier to bump the API version
  * Clipping is done completely in the wrapper

07e629a342 Allow fully scoped labels and constants instead of normal ones. This breaks 
the barrier between scopes: It is now possible to introduce symbols into a
foreign scope, provided that it's name is known.

f24adadb9c Added a first version of a Cohen Sutherland line clipper. This version 
basically works, but has rounding problems and an intermediate result overflow
in the multiplication, which causes for larger lines.

a5a9700d19 Changed handling of attributes to a more generic form (it's allowed in each

variables or functions that shouldn't be warned about.

635fae97fb If a conditional branch as an unconditional jump as target, that doesn't jump 
to a function-internal label, don't replace the jump target with the final
one, because this has no advantages and makes the code larger.

a1fb355a9a Rewrote most of the #pragma parsing code. I'm still not satisfied, but at 
least, it's a bit better than before. #pragma warn (...) is now used to switch
single warnings instead of a global on/off switch.
