Stephen Thomas commented on SQ-94:

Excellent!!! Tried on Mac, the flip and tumble tiles work great and are wonderful additions thank you Karl!!!
FYI, I tried changing rotation style to "flip up down" and "flip left right" and these do not respect the rotation center.

> The flipHorizontal and flipVertical operations on Players and SketchMorphs do not take into account rotationCenter. I have attached a tentative fix to these Morphs and also added flip and tumble commands the Viewer slots.
> The fix is partial. It only works on SketchMorphs but not on its submorphs :-(. But it is sufficient to help children create simple sketches with mirror symmetry.
