New project. New track. Generate sound -- do not cancel. Select all,
generate sound again -- this time, do cancel the progress dialog.
Undo, so you see one, empty track again. Save. Close. Reopen.
The cause of these orphans is different from the first case. The previous
commit is necessary but not sufficient to fix this.
EXPERIMENTAL_LINKING -> EXPERIMENTAL_SYNC_LOCK
Restore some "border" lines in TrackInfo.
Get rid of unused DEFINE_COLOUR( clrTrackInfoSyncLockSel...).
Clean out some undocumented commented-out code. Add/remove some comments.
Commented out the one call to TrackInfo::DrawBordersWithin(). This eliminates all the dark lines within the TrackInfo, in an effort to make the sync-lock icon not look like a button. It leaves some lighter borders, and I think that's an aesthetic improvement, though it make be worse in terms of accessibility. I can also remove the light border above the sync-lock icon, but I think this looks best overall.
In Track::IsSyncLockSelected(), for the "// Not in a sync-locked group." conditional, it returned true if the track was selected. I made it do so only if track kind is Wave or Label. Among other things, this means Time and Note tracks will never show the sync-lock icon. I think this is correct by definition, but Al, please let me know if this will have negative repercussions elsewhere. There are *lots* of calls to that method and I can move the track-type check to the code that draws the sync-lock icon..
Fixed the bug Gale pointed out where, if a WaveTrack is shrunk such that the sync-lock icon is over a TrackInfo control, such as pan slider, it didn't intercept the mouse event, and passed it on to the control. Now, clicking on the sync-lock icon does nothing.
Fixed a bug where the sync-lock icon was redrawn dark when the minimize button is down. Now not redrawn at all in that case.
Added some clarifying comments, especially about the term "Label" as used in TrackPanel.*.
