Hello,
consider a case when I want to draw a patch, but it is important how the
border is drawn. For example, if I have an aerial photo and I would like
to add a rectangle of given dimensions as a reference. Having the
rectangle interior white and its border thick and black is good, because
it ensures that the reference will be always clearly visible,
regardless of whether the photo is dark or bright.
However, as the border is thick, it may significantly overlap with the
interior, which is highly unwanted, because it will look smaller.
Therefore, in this case, I would like to draw the border, but all of it
should be outside of the patch primary area.
And I am sure that there are use cases for the opposite situation.
TL;DR: Take a look at the attached picture to see what I have in mind -
I would like to use "outer borders" (red) or "inner borders", or
classical ones, depending on my needs.
Is there a user possibility to influence how the border is drawn? If
not, how difficult would it be to implement this in matplotlib?

I recall there being discussion of controlling if paths are stroked
'inside', 'outside', or 'on' the path, but I can not find a link.
One possible work around (which is not super elegant) is to use two
rectangles, one drawn with the thick border and one with a `lw=0` and a
higher z-order overlayed on top.

This actually intersects a bit with a need of mine in basemap. In basemap,
I need to find a clip path that is just slightly bigger than the bounding
box of the map limbs so that I am not "shaving" the border line for the map
limbs. I guess I could flip the problem around and have the map limbs drawn
"inside" the specified polygon so that I don't have to worry about the clip
path shaving my limbs (... yes, I know that sounds incredibly silly).
