'' Is determined by a combination of several factors, such as direct formatting
'' that may be applied to the object, the style associated with the object,
'' as well as direct formatting And styles of the containing objects.
'' 
'' This sample demonstrates the use of the GcWordDocument.GetPropertyValueSource()
'' method that allows to find the object that provides the actual current value
'' of a style property (in this sample, the size of a font).
''
'' This sample uses the document from the SampleParagraphs sample.
