Paul Davis 1f13b311fd midi display: ensure that lollipops are visible right after import 
VelocityGhostRegion used the visibility of the "parent" note canvas item of a
lollipop canvas item to determine the lolli's visibility. But during the
construction of the MidiRegionView, the note's container is not yet visible, so
this fails.

In addition this logic would hide lollis for notes that are outside the current
visible note range of the track (because the parent note item was not visible).

This change adds a method to MidiRegionView to decide if a note is within the
region's time range, and if so, we show the lollipop item. This means that
lollis for notes outside the note-range will still be visible, which seems more
correct. In addition, the nascent condition of the parent note's container no
longer affects lolli visibility.
