I want to create a waving grass, but adding x skew I can describe as "waving flag" - the top isn't moving, while the bottom is waving. I want to create an inversed effect - the bottom of the grass should be in the place, while the top should move. One workaround is to load a rotated 180 degrees sprite, but then I need to rotate it again after adding the effect. Is there a way to ommit it? ;)
