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.
* configure.ac: re-sort Kdrive libs so that symbols get properly resolved.
Basically, all some libs are present in both $KDRIVE_LIBS and $XSERVER_LIBS,
and some libs orders are not correct. So I made sure Kdrive servers don't have
to link against $KDRIVE_LIBS *and* $XSERVER_LIBS. They just have to link
against $KDRIVE_LIBS now.
* hw/kdrive/*/Makefile.am: update those makefile to reflect the change in configure.ac

- They claim to be derived from the (MIT-licensed) ati kdrive code, yet don't

Composite's automatic redirection is a more general mechanism than the
ad-hoc BS machinery, so it's much prettier to implement the one in terms
of the other. Composite now wraps ChangeWindowAttributes and activates
automatic redirection for windows with backing store requested. The old
backing store infrastructure is completely gutted: ABI-visible structures
retain the function pointers, but they never get called, and all the
open-coded conditionals throughout the DIX layer to implement BS are gone.
Note that this is still not a strictly complete implementation of backing
store, since Composite will throw the bits away on unmap and therefore
WhenMapped and Always hints are equivalent.
I exported the evdev driver to Xephyr server. I'm running it using something
like:
$ ./hw/kdrive/ephyr/Xephyr :1 -mouse evdev,,device=/dev/input/event4 -keybd \
evdev,,device=/dev/input/event1,xkbmodel=abnt2,xkblayout=br
It also closes /#5668.
and the Xephyr virtual mouse keeps alive. With this patch the semantic changes
turning '-pointer' && 'Xephyr virtual mouse' always false.
Now we can open a device pointer and pass its options in Xephyr's command line
without having other pointer unused.
The former <X11/extensions/XKBsrv.h> has been pulled into the server now as
include/xkbsrv.h, and the world updated to look for it in the new place,
since it made no sense to define server API in an extension header. Any
further work along this line will need to do similar things with XKBgeom.h
and friends.
Only try to build Linux support on Linux. We should probably disable all
OS-dependent DDXes if we don't have a workable OS (and only build
Xephyr/Xfake), but that's future work.
Move the bell into an OS function, and use that if it's declared; else,
fall back to using the driver's function.
Remove the Linux keyboard bell function; just move it into the OS layer.
Use named initialisers when converting the old structures, and eliminate
unused functions.
