Multi-seat-capable display managers commonly pass command-line options
like "-novtswitch", "-sharevts", or "-layout seatXXXX" to Xorg server,
but Xephyr currently refuses to start if these options are passed to it,
which may break Xephyr-based single-GPU multiseat setups.

The existing driver cleanup function, scrfini, is called after the

Glamor has a mode where pixmaps will be constructed from numerous
small FBOs. This allows testing of the tiled pixmap code without
needing to create huge pixmaps.
However, the render glyph code assumed that it could create a pixmap
large enough for the glyph atlas. Instead of attempting to fix that
(which would be disruptive and not helpful), I've added a new pixmap
creation usage, GLAMOR_CREATE_NO_LARGE which forces allocation of a
single large FBO.
Now that we have pixmaps with varying FBO sizes, I then went around
and fixed the few places using the global FBO max size and replaced
that with the per-pixmap FBO tiling sizes, which were already present
in each large pixmap.
Xephyr has been changed to pass GLAMOR_CREATE_NO_LARGE when it creates
the screen pixmap as it doesn't want to deal with tiling either.

This patch fixes cursor jumps when there is a grab on the Xephyr window and
the pointer moves outside the window.
So on two side-by-side 640x480 screens, a coordinate of 0/481
triggers KdCursorOffscreen.
If the delta between two screens is 0, they share the same offset for
that dimension. When searching for the new screen, the loop always rules out
the current screen. So we get to the second screen, trigger the conditions
where dy <= 0 and decide that this new screen is the correct one. The result
is that whenever KdCursorOffScreen is called, the pointer jumps to the other
screen.
Change to check for dy < 0 etc. so that the cursor stays on the same screen if
there is no other screen at the target location.

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.

KdScreenInfo is constructed at server startup time, and not
re-generated at server reset time. Freeing the 'driver' element at
reset time means this information is lost, and the server crashes
pretty quickly afterwards.
