[Octave-patch-tracker] [patch #9280] Add data cursor functionality in plots

[Markus Mützel]

Follow-up Comment #14, patch #9280 (project octave):

"patch", "surface" and "image" objects also have x/y/zdata that could be
displayed in the data tooltip. Basically anything that is displayed in axes
must have some kind of x/y/zdata information. That is why I asked whether it
might make sense to use the "axes" function instead of changing a whole lot of
plotting functions.
I don't think any interpolation should be done.

Like I also wrote, it wouldn't be necessary to support all of these graphics
objects in a first version. But support for them can be added in the future.

For 3d scenes, I think that it would be possible to find the point closest to
the line of sight given by the two coordinates in the axes property
"currentpoint". But that also would only be a "nice-to-have" for a first
version.

Another point: It might be good to have a solid background for the annotation
to make it easier to read the numbers in busy graphs.
