Xephyr wants ctrl+shift to grab the window, but that conflicts with

A multi-head Xephyr instance has the pointer stuck on one screen

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.
