sna/gen6: Poor man's spans layered on top of the exisiting composite
Performance of this lazy interface looks inconclusive:
Speedups
========
xlib swfdec-giant-steps 1063.56 -> 710.68: 1.50x speedup
xlib firefox-asteroids 3612.55 -> 3012.58: 1.20x speedup
xlib firefox-canvas-alpha 15837.62 -> 13442.98: 1.18x speedup
xlib ocitysmap 1106.35 -> 970.66: 1.14x speedup
xlib firefox-canvas 33140.27) -> 30616.08: 1.08x speedup
xlib poppler 629.97 -> 585.95: 1.08x speedup
xlib firefox-talos-gfx 2754.37 -> 2562.00: 1.08x speedup
Slowdowns
=========
xlib gvim 1363.16 -> 1439.64: 1.06x slowdown
xlib midori-zoomed 758.48 -> 904.37: 1.19x slowdown
xlib firefox-fishbowl 22068.29 -> 26547.84: 1.20x slowdown
xlib firefox-planet-gnome 2995.96 -> 4231.44: 1.41x slowdown
It remains off and a curiosity for the time being.
