I've attempted to customize the shape of the pointer for the current
frame, what I've found out so far is that there are a text property to
change the pointer shape when hovering over it and the `x-pointer-shape'
option which takes effect on hovering over text. Looking at the xfns.c
file in the Emacs 24.4 sources revealed to me that there is a
`x-nontext-pointer-shape' option which is processed similiarly to the
`x-pointer-shape' option, however the code responsible for exposing it
in the Lisp code is commented out with a preprocessor directive.
Is there any particular reason for this peculiar decision? Or more
generally, why would a desirable feature be present, but commented out
from code? Are there any special known caveats that led to it?

I think the reasons are lost to the mist of time, [1: af01ef2643] is the commit
which ifdefs it out; the changelog is not very enlightening.
[1: af01ef2643]: 1993-05-21 20:22:10 +0000
(syms_of_xfns): Don't make Lisp vars x-mode-pointer-shape and x-nontext-pointer-shape.

We could perhaps expose these variables to Lisp again, on master, and
see if that breaks something in the long run.
