For the case of: Data mode -> curves don't exist, I think it's important
that instead of x,y,z of image under the cursor, it needs to be nearest
x,y,z that is data in the underlying matrix, with the appropriate
'datamode marker' indicating where that is.
But this conflicts with the behavior of: data mode -> curves exist ->
over an image, as if the x,y of the nearby curve are shown, there's no
reason that it would coorespond with an x,y of the image's data. The
point of datamode is that you can see actual values that coorespond to
actual data, not an interpolation thereof.
