Ghostscript based DPS extension for XFree86.

Recent diary entries for jch:
forrest: try this:
/usingGhostscript { product (Ghostscript) search { pop pop pop true } { pop false } ifelse } bind defVersion 0.0.7 of the DPS extension released.
Fixed the headers bug in the XFree86 version of pswrap. Also included three sample clients; this should prevent bugs such as the above from remaining unnoticed in the future (they will prevent the XFree86 tree from building).
A new version of the DPS extension is ready; I just need to find a while to package it up. Perhaps tomorrow. (The crashes are still there, though.)
I've finally found some time to work on DPS, and tried to understand where the reported crashes come from.
There are two known instances of crashes: when using an alpha-blending device (always), and when rasterising glyphs (sometimes). Both are due to memory corruption that happens way before the crash.
I've only been able to reproduce the latter problem when oversampling (but even then I'm not anti-aliasing). Is there any relationship betwen oversampling and alpha blending? (Both manipulate devices in interesting ways. Perhaps there's something wrong in the structure of gdevdps?)
A night of debugging, and I know nothing new.
Other than that, Francesco's patch is very nice. When used without anti-aliasing on a good display with a well-hinted font, the results are impressive. It also removes subsampling of non-anti-aliased glyphs, which, for various reasons, happens to be good for DPS (but bad for viewing TeX-generated documents with bitmap fonts).
