* clutter/eglnative/clutter-backend-egl.c:
	* clutter/eglx/clutter-backend-egl.c:
	* clutter/sdl/clutter-backend-sdl.c: Set the default resolution
	as 96.0 dpi for every backend (we already were under this
	assumption anyway, and this makes it easier to change this
	setting per-backend).

	* clutter/pango/pangoclutter-fontmap.c:
	* clutter/pango/pangoclutter.h: Allow setting the resolution
	for the PangoClutterFontMap object and provide the implementation
	for the PangoFcFontMap::get_resolution() virtual function. This
	allows to set the resolution of the PangoContext when retrieving
	it.

	* clutter/clutter-label.c (clutter_label_init): Set the
	resolution of the font map with the one the backend gives us.

	* clutter/clutter-entry.c (clutter_entry_init): Ditto.
