Hi Ilya,

Using a null-value for `shrinkA` or `shrinkB` does not achieve what you 

FWIW, I think that the method used under the hood by `FancyArrowPatch` 
is located 
while the percentage-to-points machinery in `Axes.annotate` (when 
*arrowstyle* is `None` and using the *shrink* parameter) seems to start 

Attached is a small snippet demonstrating both the percentage-based and 
the point-based shrinking possibilities, in case this might help.
