Prototype patch for 2004-10-18-trunk

Test client dbedizzy.c with print support

Usage:
% (XPSERVERLIST=:40 ./dbedizzy -printer xp_ps_spooldir_tmp_Xprintjobs -verbose)

Alan:
Can you take a look a the patch, please ?
The critical part is the new "pixmap scrubber" (the pixmap scrubber is needed,
otherwise the hidden pixmap buffer used by the DBE implementation in
xc/programs/Xserver/dbe/midbe.c will permanently fill the pixmap with new data
with each buffer swap - even if the old data are completely erased (or better:
hidden behind the PolyFill() rect of the last
clear-hidden-dbe-buffer-with-background-color-after-swapping)) - or better: the
part in |PsPolyFillRect()| which calls it:
-- snip --
+ if ( (pRects[0].x==0) && (pRects[0].y==0) &&
+      (pRects[0].width==pDrawable->width) &&
(pRects[0].height==pDrawable->height) &&
+      (pGC->fgPixel == pGC->bgPixel) &&
+      (pGC->fillStyle == FillSolid) &&
+      (noDbeExtension == False))
+ {
+   ErrorF("PsPolyFillRect: scrubbing pixmap...\n");
-- snip --
The question is: Does this |if()| statement really catch only those
|PolyFillRect()| calls which fill the whole pixmap with the background color or
are there other cases where this statement may cause the pixmap to be accidently
being scrubbed, too (for example: tiling operations or blit masks or weired ALU
operations, e.g. everything which would cause a normal |PolyFillRect()| not to
render a solid clean block in the background color over the whole pixmap
surface) ?

Test client dbedizzy.c with print support

Marking test case as obsolete, starting with bug 1673 ("RFE: Add sample
application for the DOUBLE-BUFFER extension (DBE) to the Xorg tree") the
"xdbedizzy" application is part of the tree.

New patch for 2004-10-20-trunk

I removed the |bgcolor == fgcolor| check from the |if()| as the optimisation is
AFAIK valid for all FillRect() calls which cover the whole pixmap and not only
when the application sets the color to the background.
