RE: XProc-based rasterizer

I'm not sure casting content types would be enough to fully effectuate a cast that is inherently lossy. When casting from a vector to raster image, resolution, color spaces, bit depths, aliasing among other things need to be considered. Such nuances could be handled via option parameters, but those are implementation-defined.

There is also the question of which set of casts are supported by a given XProc processor. Built for purpose steps on the other hand give a clear contract as to which functionalities are available and which aren't.
