New description:
We have two concepts of "aspect ratio" that we'd like to expose to the
user.
This patch exposes the following behavior:
{{{
* Figure aspect ratio -- controls the final image size, including any
text labels, etc. This will be set using the following options:
o figsize
+ single number - use this as a base size for the width of
the figure canvas
+ two numbers - an actual figure size in inches
+ None - use the default size in Matplotlib
o 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
o aspect_ratio -- the ratio height/width for a unit square
+ 1 -- a unit square appears to have equal height and
width. This will be the default for Graphics objects (so if a default is
not explicitly set, the default is this.)
+ 'auto' -- plot the given data limits in the given (or
computed) figsize, filling the figure (default for plot and list_plot)
+ number -- ratio of height to width.
}}}
Apply trac_2100-aspect-ratio-rebase.patch and trac_2100-auto-automatic-
and-vector.patch for this.

Comment:
This should all work fine now. I do want to point out that the standard
plots seem to have increased somewhat in size. The new reviewer patch is
now different enough that it needs review. Please do so now to avoid
bitrot!
