Brightness adjusting in RGB color space.

The filter operates in RGB color space and adjusts pixels' brightness by increasing every pixel's RGB values by the specified AdjustValue">adjust value. The filter is based on AdjustValue) and all output range to (AdjustValue, 255) in the case if the adjust value is positive. If the adjust value is negative, then all input ranges are set to (-AdjustValue, 255 ) and all output ranges are set to ( 0, 255+AdjustValue).
