Re: [Qemu-devel] [PATCH] Dead code removal: removing code for unsupported DEPTH.

qemu_create_displaysurface() creates a displaysurface with the default
depth 32bpp.  qemu_console_resize() will create a new displaysurface,
with the given size, also with the default depth 32bpp.

qemu_console_surface() just asks for the current surface, that alone
isn't a good indicator, but often display drivers use
qemu_console_surface + qemu_console_resize.
