HI, Vincent.
I just mofidied before and reverted again.
because some results are not correct.
However, I just found my build was something wrong.
It works fine now so i pushed again.
I don't know exactly why raster use those compuation
even the standard rotation fomular is there.
maybe because he uses the "direct" computation, without using the
formulas.

Log:
evas/canvas - reverted evas_map since some texture mapping is incorrect.
the maths were correct, though. Maybe there is a problem elsewhere ?
