If a screen size was specified as WxH, the loop returned early and kdOrigin
was never advanced. Thus, screen->origin was always 0 (or whatever was given
at the -origin commandline flag).
If a screen size was given with a bit depth (WxHxD), kdOrigin would always
advance by the current screen, offsetting the next screen.

When building on Solaris with _XOPEN_SOURCE set to a recent XPG release,
<stdlib.h> and other core headers start including <sys/regset.h>, which
has a bunch of unfortunately named macros such as "CS", "ES", etc. for
x86 & x64 registers which clash with existing variable & struct member
names in Xorg - so #undef these so they don't interfere with our use.
(Yes, have filed a bug against the system headers for exposing these,
but this solves the problem for building on existing releases.)

If a client passes a section of memory via file descriptor and then
subsequently truncates that file, the underlying pages will be freed
and the addresses invalidated. Subsequent accesses to the page will
fail with a SIGBUS error.
Trap that SIGBUS, figure out which segment was causing the error and
then allocate new pages to fill in for that region. Mark the offending
shared segment as invalid and free the resource ID so that the client
will be able to tell when subsequently attempting to use the segment.

ProcessInputEvent() resets the device idle times. If idle time was higher than
the lower bracket, this should trigger an event in the idle time wakeup
handler.
If processing is slow, the idle time may advance past the lower bracket
between the reset and the time the BlockHandler is called. In that case, we'd
never schedule a wakeup to handle the event, causing us to randomly miss
events.
Ran tests with a neg transition trigger on 5ms with 200 repeats of the test
and it succeeded. Anything below that gets a bit tricky to make sure the
server sees the same idle time as the client usleeps for.

The fb layer of X can't deal with strides that are not a multiple of
4, so when Xephyr allocates its own framebuffer it should make sure to
align it.
This fixes crashes and rendering corruption when Xephyr runs in a
depth that is different from the host X server and its screen size is
not a multiple of 4 / depth. (This is particularly easy to trigger if
you use the -resizeable option).

When the depth of the Xephyr server matches that of the host X server,
Xephyr simply uses the buffer associated with the XImage as its
framebuffer. In this case, it is correct to get the bits_per_pixel and
bytes_per_line values returned from hostx_screen_init() from the XImage.
However, when the depth doesn't match the host, Xephyr uses a private
framebuffer that is periodically copied to the XImage. In this case,
the returned values of bits_per_pixel and bytes_per_line should be
those of the private framebuffer, not those of the XImage.

Well, that was lame. The problem with reporting y inversion honestly is
that libGL asks the driver _its_ opinion of Y inversion, which it just
fabricates from whole cloth. So then when libGL goes to compare the
driver's idea of fbconfigs with that of the server - a fairly dumb idea
to begin with - nothing matches, and direct rendering fails, and
sadness.
So until the DRI drivers are fixed we should just continue to lie about
Y inversion. GLX_DONT_CARE is what libGL would make up for that
attribute if we hadn't sent it, so just send that instead.
