Polymer: Discard cached sprite planes on texinvalidate

Sprites would stick with their old material on global palette change.
This goes through all prsprites and clobbers their CRCs so that an
alternate skin / tint / highpal can be applied accordingly.

The winding order of faces is different if only flipping about X or Y,
and we were unconditionally culling CW faces.
