2. Setting a sprite's anchor points for handling in movement, animation, collision etc. 5. New visual attributes for sprites:
- Rotation angle
2. the sprites anchor point should be just an offset, not limited to 'topleft', 'midtop', 'topright',... and the other rect attributes
I want to be able to specify "center" or "midbottom" for the sprite anchor without knowing the image's dimensions. And I want that anchor point to remain in the appropriate place even if the image is rotated, scaled, or flipped. I'm not sure that an offset would accomplish this, but if so, then that's okay.
