Attachment: Support fast operator source support in D2D 1.1 backend

When using Direct2D 1.0 we avoid operator source very strongly. When using Direct2D 1.1 we can use it, but we should use D2D 1.1's native support for it.

Hrm, I wonder if this might be incorrect for Canvas, since I think Canvas' operators are bound by the clip and not by the mask? Whereas I think D2D 1.1's PrimitiveBlend is bound by the operation mask. I wonder if we should add an extra operator COPY where it can be bound by the primitive.

As I thought this gives trouble with Canvas. I filed bug 1066407 for adding the right operator. Patch coming to implement it here.

A no longer incorrect for Canvas version. While we discuss the desiredness of this operator next week in Toronto, I'll add D2D 1.1 to the 'hack list' for now :).
