	Reviewed by: otaylor, cworth
	* src/Makefile.am:
	Split out scaled font code to cairo-scaled-font.c
	
	* src/cairo-cache-private.h:
	* src/cairo-cache.c: (_cairo_cache_init), (_cairo_cache_fini),
	(_cairo_cache_create), (_cairo_cache_destroy),
	(_cairo_cache_preserve), (_cairo_cache_release),
	(_cairo_cache_lookup), (_cairo_cache_remove_random),
	(_cairo_cache_insert), (_cairo_cache_remove),
	(_cairo_cache_foreach):
	Replace cairo cache implementation (this code from cworth)

	* src/cairo-debug.c: (cairo_debug_reset_static_data):
	* src/cairo-font.c: (_cairo_font_reset_static_data):
	No more global glyph cache to clean up
	
	* src/cairo-ft-font.c: (_get_bitmap_surface),
	(_render_glyph_outline), (_render_glyph_bitmap),
	(_transform_glyph_bitmap), (_get_pattern_ft_options),
	(_cairo_ft_scaled_font_create), (_cairo_ft_scaled_font_create_toy),

	(_cairo_ft_font_face_create),
	(cairo_ft_font_face_create_for_pattern),
	(cairo_ft_font_face_create_for_ft_face):
	Store glyphs in new per-scaled font caches which
	hold user-space metrics and device space bounding boxes

	* src/cairo-gstate.c: (_cairo_gstate_text_to_glyphs),
	(_cairo_gstate_show_glyphs_draw_func), (_cairo_gstate_show_glyphs):
	Refactor glyph drawing APIs so that the surface API is
	invoked directly from the gstate code.

	* src/cairo-path.c: (_cairo_path_fixed_create),
	(_cairo_path_fixed_destroy):
	Add path creation/destruction routines (to hold glyph paths)
	
	* src/cairo-scaled-font.c: (_cairo_scaled_glyph_keys_equal),

	(_cairo_scaled_glyph_set_metrics),
	(_cairo_scaled_glyph_set_surface), (_cairo_scaled_glyph_set_path),
	(_cairo_scaled_glyph_lookup):
	New implementation of scaled fonts which uses per-scaled_font
	caches for glyphs and keeps user-space metrics, device-space bboxes
	along with glyph images and/or glyph paths.
	
	* src/cairo-xlib-surface.c:
	(_cairo_xlib_surface_create_similar_with_format),
	(_cairo_xlib_surface_create_similar), (_cairo_xlib_surface_finish),
	(_cairo_xlib_surface_clone_similar),

	Adapt to new scaled font API changes.

	* src/cairoint.h:
	New cache and scaled_font APIs

	* test/clip-operator-ref.png:
	* test/operator-clear-ref.png:
	* test/operator-source-ref.png:

	* test/text-antialias-subpixel-ref.png:
	* test/text-antialias-subpixel.c:
	* test/unbounded-operator-ref.png:
	Repond to bug fix in metrics computation for glyphs
	where y values were rounded up instead of down
	because of a sign difference between cairo and FreeType.
