Recompute figsize-dependent parameters on resize #5824
Description
Edit: See #5824 (comment) for the doc related issue.
Currently, applying tight_layout and resizing the figure do not commute (e.g., after subplots(2); tight_layout() and a manual maximization of the figure size, applying tight_layout again changes the margins). This is basically due to the fact that certain paddings (and text sizes) are in absolute units, which is fairly reasonable.
However, it would be nice if an option was available to add a callback to figure resize events to auto-re-tightlayout when that happens.
The following part is solved by the yet-to-be-merged #5772.
This kind of feature may become even more useful now that #5588 (number of ticks determined from physical length of axis) has been merged, as the number of ticks should, well, also be adjusted when the figure is resized (or rather, the option to do so should be (easily) available).

#5772 re-computes the number of ticks on the fly

Actually, manually adding the callback is as simple as
so just a note in the docs may be enough.
Edit: However, it appears that connecting to
draw_eventinstead does not work -- thetight_layoutseems to be computed based on the previous window size instead. This is a bit unexpected asdraw_eventis triggered afterresize_event(as can be checked by instrumenting the callback registry), so if anything you'd expect the new size to be known by the timedraw_eventis emitted...anntzer commentedon Oct 25, 2016
Actually, even better is to just use
fig.set_tight_layout(), or the rcparam associated with it. This could be mentioned in the tight layout guide (http://matplotlib.org/devdocs/users/tight_layout_guide.html), so I'm turning this into a doc issue.
