/*! Appears to be some sort of interface between RMMapContents and markers.
\bug lots of arbitrary-appearing \@synchronized blocks. Old mailing list traffic
claims they're needed, but no one seems to know why. If the #set ivar needs to be guarded,
should be done by \@synchronized(self) and not \@synchronized(sublayers). Maybe the guarding
is needed because of Core Animation thread interactions.
