XY projectors and viewers require a Converter< ? super T, ... > to work.
Just T is a too hard constraint.

mandelbrotrealrandomaccessible can have the calculation static in the
top-level class
(cherry picked from commit 2de044f796b12d525fdd4086caa6c93cc17f7df7)
added OpenConnectomeRandomAccessibleInterval (not yet complete)
similar to the CATMAID backend, it fetches small parts of a
potentially gigantic remotely stored volume on request and caches
them in SoftReferences.

added volatile types and converters and made the openconnectome connection
using it

fixed visibility of min and max in AbstractXYProjector
moved volatile types and projectors to imglib2-core net.imglib2.display
where they make most sense currently

added boolean return value to interactive viewers and renderers that
signalizes the success of painting
fixed examples
fixed painter thread logic, volatile openconnectome sets valid property
correctly after fetching and makes it available for randomaccess
OPS: update some javadoc
IterableSubsetView: fix compile error

Some previous refactoring was incomplete. I have fixed this to
get code building again. I have emailed Christian and Tobias to
check that fix is correct.
OPS: PointSets now implement EuclideanSpace
OPS: make PointSetIterator extend Iterator<long[]>
