Where is the function xf1bppScreenInit()?

[ZHANG Zhaolong]

Hi all,

I am reading xf86-video-vga-4.0.0.5 source code. It shows that:
    if (pGenericPriv->ShadowFB)
        call fbScreeInit();
    else
        call xf1bppScreenInit();

The same flow is in xf86-video-cirrus-1.3.2 too.

But where is the function xf1bppScreenInit()?

I searched in xorg-server-1.13.2.902, but didn't find the definition.

Best regards.
