ignore-redundant-mouse-moves

Arguments: cg-configuration

If the value of this Common Graphics configuration option is true, as it is by default, then an incoming mouse movement message will not call mouse-moved if the mouse cursor has apparently not really moved.

Specifically, if the window and the X and Y coordinates of the message are the same as in the previous mouse movement message, then mouse-moved is called only if the value of this option is nil.

This may avoid a problem in certain anomalous situations, such as a reported one where a continuous stream of mouse movement messages can arrive when the Emacs-Lisp Interface (ELI) is running.

cg-configuration should be a configuration object such as returned by configuration (typically (configuration *system*)).
