1.1       root        1: 
                      2:        "cfb" Beta version - 8 July 1987

                      6:        Stuart Marks            Sun Microsystems
                      7: 
                      8: With help from:
                      9: 
                     10:        David Rosenthal         Sun Microsystems
                     11:        Jack Palevich           Hewlett-Packard

                     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.
