Bug 2622 - Track name overlay is opaque

Browse Source 
Somewhere along the line the 'rect' passed in to DrawTrackName()changed
from being for the track area to being for the name area.  Accordingly
the track rect now has to be explicitly accessed from the track to get
its height, from which the transparency is then derived.
