Tomaž Vajngerl 1e92059fe9 svx: Refactor (sdr) views to access the SdrModel by reference
In SdrPaintView (and subclasses) the mpModel variable is always
the same as the input (reference) model, so there is no need for
that extra variable.

Change the strange and confusing var. name mrSdrModelFromSdrView
(the input reference to SdrModel) to just mrModel and use that in
GetModel(). Change the GetModel() to return a reference instead
of a pointer and reactor the code to accomodate the change.

This gets rid of many nullptr checks for the pointer that the
GetModel() returns and makes the code more simple is some cases.
