I have a simple Morph structure:
SlideRM(BorderedMorph)
TransformMorphRM(TransformMorph)
SlideInnerRM(PasteUpMorph)
The Transform scale was aPoint. I got error when computing the inverse
transform because Point does not understand reciprocal, see attached bug
report.
A simple fix could be a new method to Point:
reciprocal
" Answer a Point with coordinates that are the reciprocals of mine. "
" Method was missing from release. "
" 20040301 20:50:35 TRee(Squeak3.6-5429-tree07.38) "
^ x reciprocal @ y reciprocal.
