The messages sent to screen readers for these commands were incorrect when stereo tracks were present. This has been fixed, including the case where the two channels of a stereo track have different clip boundaries.

... What commit 776e4dfdaba198b0bd5a4eec3df56d67065e824b was supposed to do,
but the setting was changed in the expat library only, not Audacity.
This should prevent foolish mistakes like that fixed in the previous commit!
... in Track Contol Panel.
Each of these three can be separately referted if we don't like it.
The first is independent of theme and does not use image files.
The second uses HiliteButtonExpand.png, which looks wrong in Classic theme, as
if that file was intended for Dark instead.
The third uses files SliderThumbHilited.png and SilderThumbRotatedHilited.png
as are also used to highlight other sliders in the toolbars. The appearance
is distinguished only in Classic theme now.
Some cleanup of button drawing code is also done, removing a global variable,
and some change of arguments of other drawing functions is also done, to
make it easier to implement highlighting of other things in TrackPanel in a
way analogous to these.
Use mouse states, not events, in hit tests and choice of cursor and status.
Manage lifetimes of UIHandle objects better, without singleton instances.
Implement the mouse-over highlighting of labels more elegantly, with a system
that will allow generalization of that to other hit test targets.
Cells can report multiple, prioritized hit test targets at a point, though the
extras are not yet used.
... Because all hit tests returned all fields blank, or else, returned a
UIHandle object whose Preview method gives the rest of the information; so
the other fields were redundant.
Call HitTest in just one place
Can now preserve repeatedly hit UIHandle objects during pre-click motion
Fields of HitTestResult besides the handle pointer are now unused
The need to repaint a track during mouse movement can be indicated when
constructing a UIHandle or when updating it for move; HitPreview no longer
does this
And the last allows simplifications of LabelTrack glyph highlighting
Also move the temporary state for label glyph dragging out of LabelTrack
... Rather, construct them during hit tests (also capturing more state sooner
rather than at Click time, and adding some accessors for later use)
This also fixes bug 1677 by other means and avoids similar problems.
A cell may be implemented to re-use a previously hit handle object, not yet
clicked, in a later hit test, by remembering a weak pointer, but TrackPanel
holds the strong pointers that determine when the object is destroyed.
And the objects will surely be destroyed after drag-release, or ESC key.
For now they are also destroyed whenever not dragging, and hit-testing is
re-invoked; that will be changed later, so that the re-use mentioned above
becomes effective, but still they will be destroyed when the pointer moves
from one cell to another.
... except TrackSelectHandle. Cursor changes to a hand only after button-down.
HitTests give a UIHandle, whenever they also give any cursor or status, even
when it's unsafe to click and drag; Click override is reponsible for cancelling.
SelectHandle::Preview introduces much duplication, but the original in the hit
test will later be deleted.
... Let cell hit tests, and handle preview, know states only, not transitions.
Cell hit tests are passed a mouse state that does not always match the current,
but anticipates the button click to come; usually left, but if the Control
[sic] key on Mac is down, then right.
Thus, pressing and releasing Mac Control in multi-tool switches in and out of
the magnifier cursor.
