This function converts a RGB color value to a YIQ color value.
The color model conversion algorithm is based on the algorithm published
in section 13.3.3, "The YIQ Color Model"
of Computer Graphics: Principles
and Practice - Second Edition in C, by James D. Foley, Andries van Dam,
Steven K. Feiner, and John F. Hughes, published by Addison-Wesley

SE_COLOR_NULL_PTR_OUT_PARAMETER - if new_color_ptr was NULL.
SE_COLOR_INVALID_ORIGINAL_COLOR - if original_color_ptr is NULL. In this case, *new_color_ptr is not modified.
