Christophe CURIS bcb53700d6 WRaster: Improve error messages to provide useful information to user ...

The original error messages tended to be a bit sparse, now they try to be
a little bit more helpful, and translatable in user's language.

In xutil.c:122, took opportunity fix a problem because calling 'perror'
after other function which are likely to have changed the errno is likely
to provide a wrong error string.
