    psoTarget - Defines the surface for which the brush is to be realized
    psoPattern - Defines the pattern for the brush
    psoMask - Transparency mask for the brush
    pxlo - Defines the interpretration of colors in the pattern
    iHatch - Specifies whether psoPattern is one of the hatch brushes
 
Return Value:

    TRUE if successful, FALSE if there is an error

Routine Description:

    Implementation of DDI entry point DrvCopyBits.
    Please refer to DDK documentation for more details.

Arguments:

    psoDest - Points to the destination surface
    psoSrc - Points to the source surface
    pco - Defines a clipping region on the destination surface
    pxlo - Defines the translation of color indices
        between the source and target surfaces
    prclDest - Defines the area to be modified
    pptlSrc - Defines the upper-left corner of the source rectangle

Return Value:
