Please comment for the SPI_SETFONTSMOOTHINGCONTRAST. I'm going to use
the following formula to implement this.

gamma_encode( blend_color( gamma_decode(dst),
                           gamma_decode(text),
                           alpha );

This gamma is a different meaning from the display gamma. This is close
to the contrast. Only the formula uses the gamma correction pattern.
