Summary0000850: Write own and better version of BRepFeat_MakePrism
DescriptionThis will resolve the following problems:

1. BRepFeat_MakePrism does not always give correct results when the UpToFace is not planar (and sometimes it even makes a difference whether the UpToFace is convex or concave!!!)

2. BRepFeat_MakePrism with option "2" cannot generate a correct SubShape for Pocket/UpToFirst because the subtracted material is completely inside the support - so there is no added material

3. And if we define AddShape and SubShape as reflecting not the added/subtracted material but the design intent (see separate thread I started) then we also will not be able to use BRepFeat_MakePrism any more

and will fix the following bugs:
