Fix of "Variable layer height feature breaks after rotating part #2073"

Browse source 
There was an approximate bounding box used at the GUI, while a snug
bounding box was used at the back end, causing invalidation
of the variable layer height editing profile on rotated objects.

A snug bounding box around the first instance is now cached.
