When doing shape transformations one has to know that there
are two coordinate systems involved. The first one is the
global (absolute) coordinates system, the one that corresponds
to the document. The second is the local coordinates system
that is only relevant to a single shape. To distinguish on
which coordinate system a methods works, there is the
"absolute" prefix for the methods dealing with the global,
document based coordinate system.

methods working relative to the globale coordinate system:

absolutePosition()
setAbsolutePsotion()
absoluteTransformation() -> was transformationMatrix before
applyAbsoluteTransformation() -> was applyTransformation()

methods working relative to the shape coordinate system:

position()
setPosition()
rotate()
setShear()
setScale()
transformation()
setTransformation()
applyTransformation()

Additionally i removed the moveBy methods which used to
be relative to the global coordinate system. I removed
that one as one can simply type
setAbsolutePosition( absolutePosition() + QPoinF(dx,dy) )
to have the same effect as before.

I hope that makes it easier to use transformation of
shapes.
