Why do the tt fonts render so ugly when they are transformed to ImageMorphs or
SketchMorph using the message Morph>>imageForm. The anti-aliased edges are not
drawn to transparent but to opaque and look ugly when used in the flaps etc.
Look at the attached picture.

That's because ImageMorphs or (transformed) SketchMorphs ignore the
alpha channel. You would have to use an opaque background to blend
against, for example by embedding the text into a rectangle morph or
similar.
