> BOOL MaskedFilterExportOptions::CopyFromMasked(MaskedFilterExportOptions *pOther)
Author: Stefan_Stoykov (Xara Group Ltd) <*****@*****.**>
Created: 15/07/97
Inputs: pOther - the other MaskedFilterExportOptions object to copy the data from
Purpose: Sets the contents of this object from the passed object. This differs form the
more general function in that it doesn't require the two objects to be of the
same class. Used to convert from/to PNG options and MakeBitmapExportOptions.
