Changes the size of the model along one or more chosen axes, according to a specified factor:
either the whole model if nothing is selected
or the selected voxels
If no axis is specified, transformation applies to all of them. Factor must be a positive rational number.
The center of the transformation is located at the geometric center of the voxels concerned by the transformation.
If the scale factor enlarges the model bigger than the current object size, the limits are modified accordingly, within a 256 voxels cap for each axis.
In Euclidian geometry, this transformation is called anisotropic scaling. Cool, eh?
