    Problem Summary TSD4W.00124 This test incorrectly assumes that DirectColor color masks are always arranged as RRRGGGBB.
    Problem Text
    The assertion made by this test assumes that DirectColor color masks
    are always arranged in this way: RRRGGGBB. This is not always the case,
    and the physical arrangement is not specified by the protocol. To
    accomodate these differences in graphic hardware, the protocol requires
    that DDXs supply the client application with RED, GREEN and BLUE
    masks. This incorrect assumption on the part of the suite causes this
    test to fail on such graphic adapters.

    The test in question produces the following log:

    220|150 6 1 09:55:43|FAIL

    As you can see, the red mask is 0xe0, yet the test assumes that it is 0x3
    (Planemasks in red subfield (0x3)). The same holds true for blue, whose
    mask is 0x3, yet the test assumes that it is 0x60 (Planemasks in blue
    subfield (0x60)). If the suite had not made this incorrect assumption,
    this test would pass correctly.
    Test Output
    /tset/CH05/allcclrcll/Test 6 Failed

    Test Description:
    If the visual class DirectColor is supported: When the
    contig argument is True, and the visual type of the
    colormap argument is DirectColor, then the mask formed by
    ORing the plane masks in plane_mask_return contains three
    sets of contiguous bits set to one, one lying in each of the
    red, green and blue pixel subfields.

    Test Strategy:
    For the visual class DirectColor:
    Create a colormap.
    Allocate 1 color and some planemasks using XAllocColorCells and
    contig = True.
    Form the bitwise OR of all the planemasks per bit set.
    Verify that the returned planemasks in the red, green and blue
    subfields
    were contiguous and distinct.
