Comment (by malb):
I wrote {{{visualize_structure()}}} back in the day for visualising the
structure of dense (!) matrices over GF(2). Currently, {{{matrix_plot()}}}
doesn't behave as nicely as {{{visualize_structure()}}} for these
matrices:
* by default zero is plotted black and one is plotted white
* structure visualisation (non-zero vs. zero) is only available for
sparse matrices, but it should be also available for dense matrices (those
can be structured too).
Currently, both {{{visualize_structure()}}} and {{{matrix_plot()}}} seem
to behave the same performance wise. We should allow a matrix to plot
itself though, i.e., allow specialised code which is called by
{{{matrix_plot()}}}. For example, the M4RI library can plot matrices and
it is a lot faster than what we have in Sage.
