---------------------------+------------------------------------------------
This function (in `sage.matrix.matrix_modn_sparse` and perhaps elsewhere)
gives pngs that show up in the current working directory, which is not
standard Sage behavior for graphics. In particular, in the notebook and
`EMBEDDED_MODE` they don't show up at all, anywhere (unless you have admin
access, I suppose).
At #13807 (where this was originally not working anyway due to a previous
bugfix), it is pointed out that `visualize_matrix` does one thing that
`matrix_plot` does not: it lets you put a bound on the size of the figure,
and then scales the picture accordingly. So if you have a 20x20 matrix and
plot it in a 10x10 picture, each pixel corresponds to the entries in a 2x2
block.
There we thought it might make sense to merge this functionality into
`matrix_plot` and then deprecate `visualize_matrix`, which after all dates
from 2007. But maybe there is a reason not to do this? Anyway, any more
consistent behavior would be nice here.
