Furthermore, I'm not sure this evExpose event is really suitable for
libgwt... I would like to send to the application a gwt_region_t for
the update. I can do with a single rectangle in evExpose for the moment
(I will send several events if needed), but in the long term it may be
more intelligent to have a new event... How is it possible to
define extension-lib-specific events ?
