This isn't going to work because I forgot matplotlib shouldn't be loaded preemptively by us before user code has run. But I wanted to snapshot a working version before trying to fix that problem.

This fixes a bug introduced by #783, which was intended (in part) to allow render.plot code to set plot sizes by using matplotlib figure sizing. That code assumed that only explicit user code would cause the figure size to differ from matplotlib's default figure size (plt.rcParams["figure.figsize"]). But that's not true for seaborn, which likes to set its own sizes, which we then misidentified as being a high priority size directive that we should obey. https://seaborn.pydata.org/tutorial/function_overview.html#specifying-figure-sizes This change removes the logic that looks at whether the figure size changed. Instead, render.plot width/height can be set to 0 to cause the matplotlib figure size to be honored. However, we're not going to be emphasizing that in our docs, at least for now.

The primary goal of this PR is to provide an easy way to influence the width/height of the
output_plotthat's implicitly generated by displaying a@render.plot. There will also be a separate@output_argsdecorator that will let you set any argument on any implicit output, but the specific case of plot width/height seems like such a common case that it's worth the effort to make it dead simple.Two additional effects of this PR: the pixel dimensions of the image generated on the server side can now be influenced by
@render.plot(width=float, height=float), or if that is not specified, by using matplotlib/plotnine to set the Figure size (in inches). And it is now possible to set the DPI of a figure using matplotlib/plotnine, which changes the size of text.
