Stephan Bergmann 70cc2b191b First batch of adding SAL_OVERRRIDE to overriding function declarations
...mostly done with a rewriting Clang plugin, with just some manual tweaking
necessary to fix poor macro usage.

/** 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 rurrent 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 exsisting content to get it to the uncropped state
ans 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; inthe 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.
