RotateFlyFrame3: Added basic transformation support

In lcl_MoveAllLowers SwFrame(s) were directly modified,
not even by calling any member method what makes it hard to
react on changes to geometric definition(s). Added logic
to Transform a SwFrame, currently basic by using e.g.
SwFrame::Ltransform_translate, may be later unified to
general Transformation usage with a homogen Matrix
