| 40 | * The MaskFill operation is expressed as: |
| 41 | * dst = ((src <MODE> dst) * pathA) + (dst * (1 - pathA)) |
| 42 | * |
| 43 | * The D3D implementation of the MaskFill operation differs from the above |
| 44 | * equation because it is not possible to perform such a complex operation in |
| 45 | * D3d (without the use of advanced techniques like fragment shaders and |
| 46 | * multitexturing). Therefore, the D3DMaskFill operation is expressed as: |
| 47 | * dst = (src * pathA) <SrcOver> dst |
| 48 | * |
| 49 | * This simplified formula is only equivalent to the "true" MaskFill equation |
| 50 | * in the following situations: |
| 51 | * - <MODE> is SrcOver |
| 52 | * - <MODE> is Src, extra alpha == 1.0, and the source color is opaque |
| 53 | * |
| 54 | * Therefore, we register D3DMaskFill primitives for only the SurfaceType and |
| 55 | * CompositeType restrictions mentioned above. In addition for the Src |
| 56 | * case, we must override the composite with a SrcOver (no extra alpha) |
| 57 | * instance, so that we set up the D3d blending mode to match the |
| 58 | * D3DMaskFill equation. |
