> BOOL CCAttrMap::IsSeeThrough()
Author: Karim_MacDonald (Xara Group Ltd) <*****@*****.**>
Created: 19/02/2001
Returns: TRUE if at least one of our attrs IsSeeThrough(),
FALSE otherwise.
Purpose: Test each of the attributes in this map for see-through-ness.
This is not the same as transparency - what it means is: if I draw something
in white, then draw its outline as retrieved from PathBecomeA in black over
the top, will I still be able to see white bits?
IsSeeThrough() therefore depends partly on the implementation of PathBecomeA.
Examples:
Transparency is always see-through unless it is a zero transparency.
Line width is not see through - PathBecomeA can cope with this attr.
Fill colour is not see-through unless it is COLOUR_NONE.
Brush attrs are normally see-through, as PathBecomeA ignores them.
