virtual ErrorCode IScaleObject::Scale (const PMReal & passdownXscale,
const PMReal & passdownYscale,
ScaleContext & context 
)
pure virtual

Scale is called by the RedefineScalingCmd in order to move scaling off of an item's transform onto its content.

Parameters
passdownXscale- the horizontal scale factor that is being removed from the transform and must be realized in the content.
passdownYscale- the vertical scale factor that is being removed from the transform and must be realized in the content.
context- Most objects should ignore the context. It's purpose is to allow multiple objects that represent portions of a single model (such as the table model) to store state information and scale the underlying model once. The context is reset on each scale operation.
