AFAICS, it does it roughly the usual way, via macro 
axis.h:STORE_WITH_LOG_AND_UPDATE_RANGE().  Follow the 'update_axes' 
argument to plot_image_or_update_axes() to find it.

Well, it feels like I've preached against the way 'map' was implemented 
since day one.  Nobody listened.  Reversed axes were tricky, but still 
basically sane until the waters were muddied further by inventing 
another reason why some axis would be reverted, supposedly without the 
majority of the code noticing.  But then it turned some parts of the 
code did have to notice.  It took years to sort out that mess.  Sort of.
