The comment in Form>>copyWithColorsReducedTo:
Note: this has not been engineered.
	There are better solutions in the literature.

I bet we could do it with less than 4GB of memory!

Read in a 54x60 GIF file as a SketchMorph.
Choose painting.../reduce color palette/2 (same with 3).
My desktop is in 32-bit depth.
The corner pixels of the image are transparent.

The SketchMorph's instVars look like:

bounds: 	426 at 462 corner: 480 at 522
owner: 	a PasteUpMorph(1622) [world]
submorphs: 	#()
fullBounds: 	426 at 462 corner: 480 at 522
color: 	Color blue
extension: 	a MorphExtension (372) [other:  (rotationCenter -> 0.5 at 0.5)
(forwardDirection -> 0.0) (rememberedColor -> (Color r: 0.972 g: 0.815
b: 0.976)) (baseGraphic -> Form(54x60x32))]
originalForm: 	Form(54x60x32)
rotationStyle: 	#normal
scalePoint: 	1.0 at 1.0
framesToDwell: 	1
rotatedForm: 	Form(54x60x32)
