Under glamor, we need to re-create the screen pixmap at the new size
so that we can ask glamor for the associated texture. Fortunately, we
can simply use ephyr_glamor_create_screen_resources to create the new
pixmap.
Because this is being done after the server has started, we need to
walk the window heirarchy and reset any windows pointing at the old
pixmap. I could easily be convinced that this TraverseTree should be
moved to miSetScreenPixmap.

Currently Xephyr doesn't inherit host X server's keymap, which
may lead to keymap mismatches when using a non-US keyboard in a
window inside Xephyr. This patch makes Xephyr change its keymap
to match host X server's one (unless XKB support is disabled),
using xcb-xkb to retrieve the needed XKB controls.
This implementation is analogous to Xnest one at commit 83fef4235.

Correct byte order in the xcb_image_t structure and convert to native

If depths of Xephyr and host server differ this is already taken care of

It is a terrible wase to always convert and transmit the entire image

If a given output is passed via new -output option, Xephyr will query
host X server for its info. If the following conditions are met:
a. RandR extension is enabled in host X server;
b. supported RandR version in host X server is 1.2 or newer;
c. the given output name is valid;
d. the given output is connected;
then Xephyr will get output's CRTC geometry and use it to set its own
screen size and origin. It's just like starting Xephyr in fullscreen mode,
but restricted to the given output's CRTC geometry (fake "Zaphod mode").
This is the main feature needed for Xephyr-based single-card multiseat

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.

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.
