--untested, just ideas to get you closer
Make two images, one slightly (1/2 a degree) rotated from the first.
step the rotation of each by 1 degree, hiding and showing each thus

show grc verB  --always, one layer behind
--unless the rectangle is visible, etc.
--added optional lines for using blendlevel transitions
put 1 into cnt
repeat for 360 times
  show grc verA
  --set the blendlevel of grc verB to 0
  --wait 20 milliseconds
  --set the blendlevel of verA to 60

  set the rotation of grc verB to 0+ cnt
  hide grc verA
  set the rotation of grc verA to 0+ cnt
   --set the blendlevel of grc verA to 0
  --wait 20 milliseconds
  --set the blendlevel of grc verB to 60
  add 1 to cnt
end repeat

Not the best solution
Depending on the details of your app, you might consider a subStack with the
windowshape set to a circle, which would clip the rectangle corners, or use
maskData|alphaData to clip the rectangle corners

Hope this helps
