Account for surface trims?

Thanks for the great plugin!

I have noticed that the reflection components use the untrimmed version of any trimmed surfaces I pipe into them. Would it be difficult to make the components recognize surface trim boundaries? This would be very useful, especially for modeling surfaces with holes in them. Typically I can use shrinkTrimmedSurface, but I can't get Sonic to recognize holes without splitting the surface into multiple pieces. Thanks!
