[patch] GtkMainThread.c calculate the dpi value in case of gtk-xft-dpi can't

[Andreas Tobler]

Hi,
currently if we build the awt peers with recent gtk/pango packages we 
run into troubles if gtk-xft-dpi can't calculate a reasonable value. 
Then it returns -1 as default value and we end up with a bogus value for 
  dpi_conversion_factor.

The attached patch fixes this. Tested on darwin-7.4.0 with the TestAWT.java.

Ok on main?

	* jni/gtk-peer/gnu_java_awt_peer_gtk_GtkMainThread.c
	(init_dpi_conversion_factor): Check for int_dpi < 0 in case gtk-xft-dpi
	can no calculate the right value.
	(dpi_changed_cb): Mark *pspec as unsused.
