New description:
We have two concepts of "aspect ratio" that we'd like to expose to the
user.
* Figure aspect ratio -- controls the final image size, including any
text labels, etc. This will be set using the following options:
* figsize
* single number - use this as a base size for fig_aspect_ratio
calculations (i.e., bigger numbers = bigger figures)
* two numbers - an actual figure size in inches
* None - use the default size
* fit_tight
* if True, clip or extend the resulting figure to the plot objects
(so the resulting figure will probably not have figsize dimensions
* if False, the resulting figure has exactly figsize dimensions, but
items in the plot may be clipped or there may be excessive padding around
drawn objects
* Pixel aspect ratio
* aspect_ratio -- the aspect ratio of a pixel in the image (or of a
unit square in data coordinates, for example). The default here will
change depending on the type of plot
* 'equal' or 1 -- square pixels. This will be the default for most
things
* 'auto' -- plot the given data limits in the given (or computed)
figsize, filling the figure
* number -- ratio of height to width.
* aspect_ratio_adjust -- what should we adjust to achieve the desired
aspect ratio for the items drawn? Note that by default, the axes limits
are enlarged slightly; to eliminate this, set axes_pad=0
* 'box' (default) -- the frame axes
* 'datalim' -- the data limits
