 Convert To 8-bit Gray

This function is used convert the current image into a 8-bits per pixel image (1 plane of 8-bit grayscale data).

When the image source is color, the color data is converted into a grayscale value.  If the data is greater than 8 bits in depth, only the most significant 8 bits are used. 

When the image source is Gray 16, the most significant 8-bits are copied into the respective planes.  If it is a floating-point image, the intensity range is calculated and used to divide the image into 256 gray values.

This function does nothing if the image is already the correct type.

This function works on the current image.  The result is a new image.
