This initial implementation blooms into everything - so it's going to
blur to some degree, if you use the filter. You can lesson the bloom
strength - make things sharper, but then the bloom effect itself fades.
An enhancement that could be tried I suppose, would be to leave "dark"
to some criterea regions untouched. Not sure how "natural" it would
look. More complicated things always possible - but then it might be
rendering large and scaling down say is a better way to go. At some
point if you don't want a bloom filter, you are into something else.
On the time to run this filer... I remembered after posting I was using
a development, '-O optimization only', build. It'll be faster with a
normal performance compile/link - but still expensive.
