Setting pointer color

[Rich Shepard]

Running lyx-2.3.6.1 on Slackware64-14.2.

When the trackball/mouse pointer (a thin 'I') is on the last modified text
position (the emacs 'point') its color is red. But, when it's being moved
its color is black.

Quite often my eyeballs (with many millions of miles on them) lose track of
the moving pointer's position. Is there a way to change the color of the
moving pointer to something other than that thin black 'I' so it isn't lost
among all the black text?
