SVG has a well-defined notion of a "filter effects region", doesn't it?
It seems like sizing the export region for selection according to the union of the normal rendering bboxes and the corresponding filter effects regions is all one could reasonably ask for.
Yes, filter effects region is well defined and by definition big enough to hold all pixels the filter will affect.
This sounds like a viable method. The only shortcoming I see is that this will result in some images getting enlargened for no apparent reason. For example, using blending modes instead of blur, the filter effects area still is the default of bounding box + 10%, even though blending doesn't enlarge anything.
