Søren Sandmann Pedersen 97cf53cc2a ephyr: hostx_screen_init(): Fix bits_per_pixel and bytes_per_line ...

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.
