The angled process does not collide according to collision()!
It does work with height==1 pixel, but not with width==1 pixel.

I know... this is a float precision stuff...

oh, sorry, I interpreter other stuff... let me take a look... thanks...

yes, again...
"I know... this is a float precision stuff.."

well, I think so... the problem maybe is gr_rotate_blit.
