yes. just draw triangular buttons and have transparency where you dont want
them hit (on the image), use the image as he hit area and add:

precise_is_inside: 1;

so the part (alone with scale, type, name etc.). this basically makes evas use
the actual pixel alpha to determine if a point is inside the image or not, as
opposed to just is bounding region (which is normal).

nb - NEVER tested this before...

that's up to him, but, since i know it's patented now - i am not touching it.
willfully violating a patent with knowledge is much nastier than accidentally
violating one you dont know about.
