Thanks for trying out the patch. I should have included a warning in my post.
The patch only adds flip commands to the viewer of a SketchMorph. The
SketchMorph methods themselves are broken. I use the patch to compose
sketches with mirror symmetry and then grab the composite for a single
sketch. Kludgy, but a stop gap till etoys get true transformation
Flips don't work on rotated sketches because the flip* methods of SketchMorph
are broken. They switch the form (which resets the rotationCenter) :-(.
Rotations, flips, shear and scale, being views on the base image, should
affect only the view transform values and not the base form.
Let me see if I can come up with a patch that will fix this.
