pcolorfast results in invalid cursor data

[anntzer]

mpl2.0b3 (and likely ever since get_cursor_data exists).
The PcolorImage class does not redefine the get_cursor_data method, so it displays incorrect cursor data:

In [1]: plt.gca().pcolorfast([0, 1, 3], [0, 2, 3], np.arange(4).reshape((2, 2)))

then hover the cursor over the image to see incorrect values in the status bar.

By the way, the NonUniformImage class suffers from the same problem. This is less obvious from the example (pylab_examples/image_nonuniform.py) as it directly adds the image to ax.image, so the image is not added to the mouseover set. But switching these lines to use ax.add_image(im) reveals the same issue.

Yes, I'm aware of that, but it is lower priority because as far as I know we have no direct Axes interface like pcolorfast to the NonUniformImage class; I suspect it is rarely if ever used. (I don't know how much use pcolorfast gets, for that matter; I wrote it because I wanted it, and I use it, but maybe no one else does.) Also, handling the data cursor for PcolorImage is fast and easy. It's not so obvious to me how to handle NonUniformImage.
