FastBlendBitmap(const TPoint &, CFbsDrawDevice *, const TRect &, CGraphicsContext::TDrawMode, TInt)
Performs blended blitting. The interface can selectively supports various combinations of source and destination. Assumes that aSrcRect is contained by the source device. Assumes that the resulting destination rectangle is contained by the destination device.
Parameters
| const TPoint & aDest | Logical coordinates of the position in the target that the result should be drawn to. |
| CFbsDrawDevice * aSrcDrawDevice | Draw device that will act as the source of the blit. |
| const TRect & aSrcRect | The rectangular region of the source to be blitted. |
| CGraphicsContext::TDrawMode aDrawMode | Current draw mode |
| TInt aShadowMode | Current shadow mode |

| const TUint32 * aSrcBase | Base address of the source bitmap. |
| TInt aSrcStride | Length in bytes between scanlines of the source bitmap. |
| const TSize & aSrcSize | Size of the source bitmap in pixels. |
| const TRect & aSrcRect | The rectangular region of the source to be blitted. |
