Detailed Description

CropPrimitive2D class.

Caution: Due to old constraints (old core definitions) the crop distances describe how the uncropped content is defined relative to the current object size. This means that maTransformation describes the current object size (the part of the object visible with the crop applied). To get the original size and orientation of the uncropped content it is necessary to calc back from the current situation (maTransformation) using the crop values to get to the uncropped original content.

Thus a transformation has to be calculated which will be applied to the already existing content to get it to the uncropped state and then this is masked with the current state (mask polygon created from unit polygon and maTransformation).

At least in this primitive the units of the crop values are already in the local coordinate system; in the core these distances are defined relative to the object content size (PrefMapMode and PrefSize of the content)...

Of course this is a primitive, so feel free to just ignore all that stuff and use the automatically generated decomposition. Sigh.
