Comment:
Thanks for your comments !
I found an almost-clean solution for the problem raised by the triangular
grid paths. Instead of computing directly the `height()` and `width()`
functions, I introduced the `xmin()`, `xmax()`, `ymin()` and `ymax()`
functions we talked about. They are called by the two first functions. To
solve the problem for the triangular grid paths, I just redefined them by
coercing the x- and y-coordinates to real values, so that the `max` and
`min` functions be well-defined.
I'll upload another patch in a few minutes. Needs review !
