You need to iterate through all selected text items and compare properties

of their text styles.

For example, this work is done in RichViewActions, TrvActionFontEx.

When it's run, it determines which attributes are "consistent" and their

values.

It writes a list of "consistent" attributes in ValidProperties property, and

their values in the corresponding properties.

This work is performed in the procedure TrvActionFontEx.GetFromEditor.

When this action displays its dialog, only "consistent" attributes are set

(others are in indeterminate state: indeterminate checkboxes, comboboxes

with no selection, blank numeric editors, etc.). So, if user just presses OK

without making any modifications in this dialog, nothing will be changed.
