Therefore, the D3DMaskFill operation is expressed as: 0N/A * dst = (src * pathA) <SrcOver> dst 0N/A * This simplified formula is only equivalent to the "true" MaskFill equation 0N/A * in the following situations: 0N/A * - <MODE> is SrcOver 0N/A * - <MODE> is Src, extra alpha == 1.0, and the source color is opaque 0N/A * Therefore, we register D3DMaskFill primitives for only the SurfaceType and 0N/A * CompositeType restrictions mentioned above. In addition for the Src 0N/A * case, we must override the composite with a SrcOver (no extra alpha) 0N/A * instance, so that we set up the D3d blending mode to match the 0N/A * D3DMaskFill equation. 0N/A int x,
