        !             2:        "cfb" Beta version - 8 July 1987

        !             5: 
        !             6:        Stuart Marks            Sun Microsystems
        !             7: 
        !             8: With help from:

        !            13: 
        !            14: This directory contains an analogue of "mfb" for memory color framebuffers.
        !            15: It can be configured to support a number of different devices:
        !            16: 
        !            17:        -       They must be organised as packed pixels,  not planewise.
        !            18:        -       They must have fewer than 32 bits per pixel.
        !            19: 
        !            20: The code has been tested only on displays with a pixel size of 8 bits,
        !            21: both with all 8 planes implemented (Sun) and less than 8 planes implemented (HP).
        !            22: As distributed,  it is set up for 8-bit pixels with all 8 planes implemented.
        !            23: If your display is different,  see maskbits.h.
        !            24: 
        !            25: The code is intended to be highly portable,  and to use as much as possible of the
        !            26: "mi" code.  As a result,  it is very slow.  But we believe it should be very
        !            27: easy to port.  We believe that the code only ever accesses the framebuffer 32 bits
        !            28: wide at 4-byte aligned addresses.
        !            29: 
        !            30: As delivered,  the code supports a PseudoColor visual.  By defining STATIC_COLOR,
        !            31: you can configure it (and the .../sun directory) to support a StaticColor visual
        !            32: instead.  This has proved useful in testing the server.
        !            33:
