Let’s not break backwards compatibility. There is little to no information what “rotated” means so I guess I have to change the way it rotates the sprite. Would you mind to help me out with this and tell me how is it supposed to be so I don’t have to look it up? Is it 90CW or 90CCW, or whatever else? Thanks!
EDIT:
I’ve figured it out, hopefully 
Changes committed.
So this is the current status
Not rotated:
Rotated:
So it rotates CCW 90.
New, not rotated:
New, rotated:
CCW 90.
Should be OK!
