[Cuis-dev] Clipping operation

[Thierry Goubier]

Hi Hilaire,

in Cuis, Submorph clipping only happens for one submorph, and only if
aMorph>>#clippedSubmorph is true (and that clips to the parent morph, so,
if your wheel morphs are submorphs of your overall frame, then incorrect
clipping for the clipped submorph).

In a case like yours, you will probably need to add a morph that do nothing
but clipping, to ensure that the morph you are drawing in has the exact
same bounds as its parents.

The code in charge of that is MorphicCanvas>>#fullDraw:
The code selecting the clipped submorph is Morph>>#clippedMorph. By
default, it is the last one.

Thierry
