You have to change the zp_* keys from gnopernicus.schemas file. The
values from  srconf/libsrconf/libsrconf.h are really used if no gconf
value is found.

The default schemas values are  (0, 0) - (MAX_INT, MAX_INT). They will
be truncated to (0, 0) - (screen width, screen height) for every user.
Those values are chosen because a users use to use magnifier in full
screen and not in partial magnified mode. 

NOTE: If you change a key in gnopernicus.schemas file, be sure you run
"make install" after and "gconftool --shutdown" otherwise, when
gnopernicus runs for second time is possible to use the old values
because the gconf daemon keeps a "cache" for used keys.
