To answer my own question, unfortunately, this isn't always the case.  
There is also a bug where if a masked region is inside of the *inner* 
polygon of a contour, the inner contour is incorrect.  So, other 
advantages aside, adding support for compound polygons won't magically 
fix any of the contour problems.
