filter-blur: Allow applying Blur to a sub-region of the source only

Browse source 
The Blur Filter can now be applied to a region inside the source itself, the inverse of that region, and/or a feathered version of that region. This allows for easier scene setups where only some parts need to be blurred, but the rest can be left as is.

Fixes #12
