    fix coredumps in XRenderComputeTrapezoids (issue #1)
    
    Rationale: I don't have enough expertise to judge on how the tessellation
    algorithm is broken in XRenderComputeTrapezoids but I do trust Keith Packard
    that it is. However using cairo for proper tessellation, as he suggests, is
    too heavyweight, and here I propose to alter the code to at least do not cause
    coredumps.
    
    Even if/when the function will be marked as obsolete, I believe it is pretty
    much capable of rendering relatively simple shapes, and still retains some
    value.
