Log Message:
	reviewed by: cworth, otaylor

	* src/cairo.c: (cairo_set_antialias), (cairo_get_antialias):
	* src/cairo.h: Add a new API for disabling antialiasing of shapes
	drawn by cairo.  This is a hint and is not supported by all backends.

	* src/cairoint.h:
	* src/cairo-gstate-private.h:
	* src/cairo-gstate.c: (_cairo_gstate_init),
	(_composite_traps_draw_func),
	(_cairo_surface_clip_and_composite_trapezoids),
	(_cairo_gstate_clip_and_composite_trapezoids),
	(_cairo_gstate_clip), (_cairo_gstate_set_antialias),
	(_cairo_gstate_get_antialias): Store the antialiasing mode in the
	gstate and pass it to the backend for trapezoid rendering and for
	clipping.

	* src/cairo-clip-private.h:
	* src/cairo-clip.c: (_cairo_clip_intersect_path),
	(_cairo_clip_intersect_mask), (_cairo_clip_clip): Pass the
	antialiasing parameter down to the backend where appropriate.

	* src/cairo-surface.c: (_fallback_composite_trapezoids),
	(_cairo_surface_composite_trapezoids), (_cairo_surface_reset_clip),
	(_cairo_surface_intersect_clip_path),
	(_cairo_surface_set_clip_path_recursive),
	(_cairo_surface_set_clip_path): Pass the antialiasing parameter down
	to the backend where appropriate.

	* src/cairo-image-surface.c:
	(_cairo_image_surface_composite_trapezoids): Add support for A1 format
	trapezoid rendering, and remove the _create_mask_image function,
	creating a temporary image from memory we allocate and clear.

	* src/cairo-xcb-surface.c:
	(_cairo_xcb_surface_composite_trapezoids): Support A1 masks to disable
	antialiasing using the RENDER extension when requested.

	* src/cairo-xlib-surface.c: (_create_trapezoid_mask),
	(_cairo_xlib_surface_composite_trapezoids): Support A1 masks to disable
	antialiasing using the RENDER extension when requested.

	* src/cairo-meta-surface-private.h:
	* src/cairo-meta-surface.c:
	(_cairo_meta_surface_composite_trapezoids),
	(_cairo_meta_surface_intersect_clip_path),
	(_cairo_meta_surface_replay): Blindly pass through the antialising
	parameter.

	* src/cairo-glitz-surface.c:
	(_cairo_glitz_surface_composite_trapezoids):
	* src/cairo-pdf-surface.c:
	(_cairo_pdf_surface_composite_trapezoids),
	(_cairo_pdf_surface_intersect_clip_path): 
	* src/cairo-ps-surface.c: (_cairo_ps_surface_composite_trapezoids),
	(_cairo_ps_surface_intersect_clip_path),
	(_ps_output_composite_trapezoids),
	(_ps_output_intersect_clip_path): Add the antialiasing parameter but
	don't support it.

	* test/Makefile.am:
	* test/unantialiased-shapes-ref.png:
	* test/unantialiased-shapes.c: (big_star_path), (draw), (main):
	Add a test case and a reference image from the latest libpixman.

	* doc/public/tmpl/cairo-font.sgml:
	* doc/public/tmpl/cairo.sgml:
	* doc/public/cairo-sections.txt: Add the new antialiasing disabling API to
	the docs.

	* TODO: Update progress on a parameter to disable antialiasing.
