Use to check for colors outside the range 0.0 - 1.0. 
Normally IN is passed to both EOUT and COUT, unless IN falls outside 0.0 - 1.0,
in which case EOUT passes the Error Color (ERR), and COUT passes IN clamped 0.0 to 1.0.

Input color to be checked.

This controls whether to print color transgressions or not.
If True and IN falls outside 0.0 - 1.0, IN is printed to the screen.

The 'Error Color'.
If any RGBA component of IN goes outside the range 0 - 1,
this 'error color' is returned on OUT.

Error Color. Use this to flag 'out of range' colors with the error color.
This normally passes the color of IN, unless it is outside 0.0 - 1.0,
in which case it is replaced with the error color (ERR).

Clamped Output Color. Does NOT include the error color.
If the input color falls outside the range 0.0 - 1.0, it is clamped.

Print flag output.
Returns miTRUE if failed range test.
Use this output to trigger other actions to occur.
