2000-02-02 Federico Mena Quintero <federico@helixcode.com> * gdk-pixbuf/io-gif.c (gif_get_lzw): Removed debugging g_print. Thanks to John Sullivan <sullivan@eazel.com> for the patch. * gdk-pixbuf/testpixbuf-drawable.c (configure_cb): Get a new area of the screen when the window is resized. Thanks to David N. Welton <davidw@linuxcare.com> for pointing this out. Misc. cleanups to the rest of the file.
