Flipping drawing

Bug Description

There is some problem with drawing accuracy. See attached screenshot.

It is not a computational problem in the geometric model, but it looks like related to rounding error in transformation from world coordinates to display coordinates. Indeed the flipping occurs when zooming or moving the sketch, and when doing so there is no computation in the geometric model.

Problem comes from Rectangle>center as it does computation with an Integer division, and for DrGeo we need a Float division.

Override appropriately the related code in our DrGMorph hierarchy.
