Does the attached patch help? It should promote a8 masks to arg

Hi,
1.) As far as I have seen the only way to get aliased rasterization
with XRenderCompositeTrapezoids is to pass PictStandardA1 as mask
format.
However a lot of hardware can't use A1 as mask, leading to a fallback.
On my 945GM I get for a 100x100 circle consisting of ~180 traps:
20ms, A8
120ms
