It appears to be stretching the arrow to fit in the rectangle defined by its points. Doesn't seem to be the right transformation. However, it looks as if it's been that way for a long time. Was this working for you at one time and then it broke, or is this your first attempt with FancyArrow? None of the matplotlib examples use FancyArrow.

Python 2.5 changed the type of those arguments to "const char *" to avoid this warning.
