As far as I can see it is, because the effect is exactly the same
whether I use PFDECAL_BASE_STENCIL or PFDECAL_BASE_HIGH_QUALITY.
Neither gives the desired result in my case. Has anyone successfully
used STENCIL mode in pf2.x for pfLayers?

Roll on 2.2 then (release date?). Is there any particular reason why
the Z buffer algorithm in the article "The hidden charms of the Z
buffer" is not provided as one of the Performer modes for rendering
decals?
