remove SizeScale and Rotation from Advanced Menu
Browse files Browse the repository at this point in the history 
The expressions used in old project are converted to symbol level
DadaDefined size and angle

Note that sice the aspect of a composite marker is fixed for symbol size
and angle, the aspect of the scaled symbol will change for symbols with
offsets and composite markers.
