Update to 1.2.1:

This release adds a "-event" option that can be used to filter which \ 
events are
printed.  For example, to listen only for RandR events, use "xev -event \ 
randr".
The -event parameter can be specified multiple times.  Please see the manual
page for the list of available event filters.

This release also contains a few code fixes.
