Thanks to Owen Taylor for root-causing this one.
If a TreatAsTransparent window has any area in the borderClip, that will be
added to the totalClip region for use by other windows. That's wrong.
Instead, simply empty the borderClip for TreatAsTransparent windows right up
front.
This extension provided bug-compatibility with pre-X11R6, but has been
stubbed out in our server since 2006 to return BadRequest when you actually
asked for it.
When we fail an assert in miregion.c (which happens every now and then,
though I haven't yet checked up why), at least generate a segfault, so
we'll get a backtrace.
Initialise num_events to 1, so we always send a proximity event, and then
optionally valuator events. Also make sure mieq can deal with valuator
events sent after proximity events.
These hints allow an acceleration architecture to optimize allocation of certain
types of pixmaps, such as pixmaps that will serve as backing pixmaps for
redirected windows.
This changes the module initalization order so that the GLX module initializes
after COMPOSITE. The reason for this change is to be able to initialize a
GLX visual config for the COMPOSITE ARGB visual.
Instead of the fragile setup where we filter the modes common between the
DDX generated GLX visuals and the DRI driver generated fbconfigs, we now
just take the fbconfigs returned by the DRI driver to be our supported set.
* dix/events.c, include/dix.h:
(UpdateSpriteForScreen): added this to update the mouse sprite context
when we switch from a pScreen to another.
* mi/mipointer.c:
(miPointerWarpCursor): as we are switching to a new pScreen,
don't forget to update the mouse sprite context.
This was an attempt to avoid scratch gc creation and validation for paintwin
because that was expensive. This is not the case in current servers, and the
danger of failure to implement it correctly (as seen in all previous
implementations) is high enough to justify removing it. No performance
difference detected with x11perf -create -move -resize -circulate on Xvfb.
Leave the screen hooks for PaintWindow* in for now to avoid ABI change.
Instead of drawing to window pixmap for everything, draw to window for
background as that works for Xnest and Xdmx; draw to pixmap for borders
which neither of those X servers use.
miPaintWindow was drawing to the root window, or (sometimes) drawing to the
window after smashing the window clip list. This is losing, and easily fixed
by just drawing to the window pixmap.
over to new system.
Need to update documentation and address some remaining vestiges of
old system such as CursorRec structure, fb "offman" structure, and
FontRec privates.
