[Octave-bug-tracker] [bug #61030] [octave forge] (image) Don't use internal function

[Markus Mützel]

Follow-up Comment #10, bug #61030 (project octave):

The attached patch adds a configure check to test if the `dim_vector` class
has an `xelem` member function. If it doesn't, it would fall back to the
`elem` function (with the additional cost of boundary checking).

I haven't tested at all, so it might need some tinkering. If it works, it
should define HAVE_OCTAVE_DIM_VECTOR_XELEM if that function exists.

I also don't know the coding style of the image package. I hope it is ok.
