Carl Hetherington c91da28eb2 Some improvements to performance with crossfades: don't recompute a whole track's crossfade curves
when one region is moved and the display is overlaid; use a std::map for an AudioStreamView's crossfades
list so that add_crossfade can find whether a CrossfadeView already exists without looking through
the whole list.
