The advantage of the PostScript stencil model, as it was explained to me, is that: 1) It is possible to have device independent imaging. B&W vs Color, high res vs low res., non-rectangular pixels, etc. 2) It supports a write-only model. The advantage of the write-only model is you can have multiple processes and/or a pipeline when writing data to the screen. XOR-ing makes pipelining the data difficult. -- Bruce G.
