[Etoys] [BUG] TransformationMorph changes border behavior

[karl]

When for example a RectangleMorph is rotated its border behavior changes 
from a unrotated RectangleMorph.

To see this, set the border of a RectangleMorph to 20 pixels.
Scale it with the halo; border width is not scaled.
Rotate the morph and try scaling again; border width is scaled.

Also when unrotated the scaling handle stops when the morph is at it's 
smallest, a rotated morph scales down and up again when the mouse goes 
past the top left corner of the morph.
