Log Message:
Add a set of three hooks for accelerating trapezoids, and use it for
the RasterizeTrapezoid screen function.  These hooks will be called for
imprecise, non-sharp trapezoids with A8 destinations.

Note that the current main consumer of trapezoids, cairo, is requesting
precise, sharp trapezoids by not changing the default Picture
attributes, but gets non-sharp effects in software because fb bases its
choice of sharp/non-sharp on the mask format being A8 vs A1, and cairo
asks for A8.  Follow fb's (poor?) example by ignoring the sharp setting
and basing the choice off of the mask being A8.
