[Spice-devel] [PATCH] add compat flag for 16bpp mode

[Gerd Hoffmann]

spice 0.6 uses 32bpp values unconditionally for brush and palette
colors.

spice 0.4 used to use 16 bpp or 32 bpp depending on the video mode.
The qxl parser needs to know the guest video mode depth to correctly
interpret these values in spice 0.4 compat mode.  Add a flag to pass
on this informartion.
