+	* gdk-pixbuf-loader.[hc] (gdk_pixbuf_loader_new_with_mime_type): New function to obtain a loader for a specific mime 
+	type.  (#105324, Dom Lachowicz)

 	* io-gif.c (gif_get_extension): Reset block_count to 0 for all application extensions, otherwise the data blocks 
 	of unknown extensions are not propertly skipped.

+ * Return value: A newly-created pixbuf loader.
