[gui][PATCH] Fix font size calculations in GTK peers

[Thomas Fitzsimmons]

Hi,

I committed this patch to java-gui-branch.  It adjusts font size
calculations in the GTK peers to factor in the screen's DPI.  The AWT
specifies font sizes in pixels but we were interpreting them as points.

	* gnu/java/awt/peer/gtk/GtkTextAreaPeer.java (create): Set
	"Dialog" as the default font.
	* gnu/java/awt/peer/gtk/GtkTextFieldPeer.java (create):
	Likewise.
	* java/awt/Component.java (getFont): Return "Dialog" font by
	default.
	* jni/gtk-peer/gnu_java_awt_peer_gtk_GdkClasspathFontPeer.c:
	Multiply size argument to pango_font_description_set_size by the
	DPI conversion factor rather than by PANGO_SCALE.
	* jni/gtk-peer/gnu_java_awt_peer_gtk_GdkFontMetrics.c: Likewise.
	* jni/gtk-peer/gnu_java_awt_peer_gtk_GdkGraphics.c: Likewise.
	* jni/gtk-peer/gnu_java_awt_peer_gtk_GtkButtonPeer.c: Likewise.

	* jni/gtk-peer/gnu_java_awt_peer_gtk_GtkTextFieldPeer.c: Likewise.
	* jni/gtk-peer/gnu_java_awt_peer_gtk_GdkGraphics.c (drawString):
	Divide baseline y coordinate by DPI conversion factor rather
	than by PANGO_SCALE.
	* jni/gtk-peer/gnu_java_awt_peer_gtk_GdkPixbufDecoder.c
	(area_prepared): Fix typo.
	* jni/gtk-peer/gnu_java_awt_peer_gtk_GtkLabelPeer.c
	(gtkSetFont): Move gtk_bin_get_child inside GDK critical region.
	* jni/gtk-peer/gnu_java_awt_peer_gtk_GtkMainThread.c
	(dpi_conversion_factor): New global variable.
	(init_dpi_conversion_factor): New function to calculate and
	track DPI conversion factor.
	(dpi_changed_cb): New callback.
	* jni/gtk-peer/gtkpeer.h (dpi_conversion_factor): Declare.
