[Spice-devel] [PATCH spice-protocol] Add QXL_ESCAPE_SET_CUSTOM_DISPLAY

[Marc-André Lureau]

QXL_ESCAPE_SET_CUSTOM_DISPLAY is Windows specific message
to tell the display & miniport driver to update the mode
table with a custom resolution.

The mode table needs to be forcefully refreshed after
setting a custom display, it can be done by querying an
invalid/unknown mode:

EnumDisplaySettings(dev_name, 0xffffff, &tempDevMode);
