	* src/cairo-gstate.c: Implement new equations for CLEAR and SOURCE
	CLEAR: (mask IN clip) ? 0 : dest
	SOURCE: (mask IN clip) ? src : dest
	That behave more like what people expect.

	* src/cairo-gstate.c (_cairo_operator_bounded): CLEAR and SOURCE are 
	now bounded.

	* src/cairo-font.c (_cairo_ft_scaled_font_show_glyphs)
	* src/cairo-surface.c (_cairo_surface_composite_trapezoids):
	Assert that SOURCE and CLEAR aren't passed to these functions.

	* src/cairo-surface.c (_cairo_surface_composite):
	Assert that SOURCE and CLEAR aren't passed to these functions
	when there is a mask.

	* src/cairo-xlib-surface.c (_cairo_xlib_surface_composite)
	* src/cairo-image-surface.c (_cairo_image_surface_composite): 
	Do fixups for SOURCE and CLEAR as well as unbounded operators,
	since in the absence of a mask, we need SOURCE to work 
	correctly (don't care about CLEAR)

	* src/cairo-ft-font.c (_transform_glyph_bitmap, _cairo_ft_font_show_glyphs)
	Consistently use CLEAR/TRANSPARENT (source doesn't matter)
	rather than SOURCE/TRANSPARENT when clearing rectangles.

	* src/cairo-xlib-surface.c src/cairo-surface.c: Use 
	IN rather than SOURCE as an example of an unbounded operator in
	docs.

	* test/unbounded-operator.c: Remove CLEAR/SOURCE columns since
	they are no longer unbounded.

	* test/operator-clear.c test/operator-source Makefile.am: Add
	targetted tests of CLEAR/SOURCE.
