SDL on wide gamut

Hi,

Is SDL at all able to use colors with 10 bits
per channel? So far I've seen that my driver
selected by default is opengl. And that uses
the format ARGB8888, while the monitors format
would be RGBA1010102. I've seen that there is
such a symbol for packed pixels, but I can't
see, how I would proceed to specify the colors
with this depth. I'm using the proprietary X11
video driver from nVidia for wide gamut
monitors, so I guess that shouldn't be
considered that exotic anymore after all.

Thanks,
