Coefficients of the YUV->RGB conversion formula.

A set of coefficients configuring the RGB to YUV conversion. Coefficients 0-4 are unsigned 2.8 fixed pointer numbers representing entries on the conversion matrix, while coefficient 5-7 are signed 11.5 fixed point numbers added as offsets to the RGB result.

The overall conversion process formula is:

R = trunc((rgb_Y * Y + r_V * V) + 0.75 + r_offset)

G = trunc((rgb_Y * Y - g_U * U - g_V * V) + 0.75 + g_offset)

B = trunc((rgb_Y * Y + b_U * U ) + 0.75 + b_offset)

The overall conversion process formula is:

R = trunc((rgb_Y * Y           + r_V * V) + 0.75 + r_offset)

+G = trunc((rgb_Y * Y - g_U * U - g_V * V) + 0.75 + g_offset)

+B = trunc((rgb_Y * Y + b_U * U          ) + 0.75 + b_offset)
