Recently AndrewR showed me several memorandums about some defined standards
for high bit depth video. It is definitely stated there: the ranges of all
the color channels must be inside 0.0 - 1.0 (it was meant RGB float type).

Therefore, to comply with the existing standards, color data MUST be clipped
between 0.0-1.0, otherwise they are illegal!

The only parameters which can control the colors precision, max brightness,
darkness etc., are actual bit precision, and the actual value of white point
and black point, gamma or color curves, etc.

Perhaps, it was (still is?) some misunderstanding about what you mean under
'clipping'.
