This function increases or decreases a Destination POV by a percentage factor. The percentage factor may be taken from a Source POV, a VBScript constant or a VBScript variable.
In general, the Source POV is the same as the Destination POV, however, it can be different.
The Scale parameter is used to scale down the factor, if required. This applies when the factor is taken from a Source POV and the factor is stored in a non-scaled form (for example, 50% is stored as 50 and not 0.50).
The Inverse parameter is used to reverse the sign of the factor. This applies when the factor is taken from a Source POV and the factor is stored as an absolute number. If the Inverse parameter is set to True, the factor is multiplied by -1. If the Inverse parameter is set to False, the factor is not multiplied -1.
