Hi! A question regarding animating a rotation transformation defined by plottools[transform]. I can get the shear, translation and stretch to be animated. But when I use the same commands for rotation, the output doesn't appear. Here are my commands attempting to animate the rotation:

with(plots):

with(plottools):

with(LinearAlgebra):

p:=plottools[rectangle]([0,1],[1,0])

g:=transform((x,y)->convert(Multiply(Matrix([[cos(r), sin(r)...
