Re: [cc65] TGI preview

I haven't checked the sources/docs on that so please have mercy if it's already there or something but I was wondering how difficult or easy would it be to have the "reversed" version of the GI. I mean one where clearing would fill the screen with ones instead of zeros, and every drawing would clear the bits out by setting them to zeros.

This could be done f. e. by passing an arg to tgi_init () to set the drawing context. Of course drawing functions could take similar arg but setting the context globally would be good for start.

Why would one do that? I believe that this would allow some easily achievable, and CPU efficient effects on most platforms - like flashing, colour rotations, etc. just by changing the background colour, which (I guess) is possible not only on C64 and Co..

Does that make some sense?
