Well, my point about this is how rgb ought to prevent rgbft from being used.
I can see how your logic would work were there no "rgb" but its presence
should mean anything following it is a 3 float vector. And even though my
example had all 5 it still does the promotion to 5 when all are only 3. The
filter and transmit keywords should be what is needed to get back to all 5
again from that rgb color value.
That's my reasoning anyway.
What you've said is essentially that a <red,green,blue,filter,transmit> is
omnipresent regardless of choosing to use rgb alone. Again, I can see that
being likely once using the 5 floats vector afterward but they are set to
zero. 1-0=1 but only if rgb 1 = rgbft 1.
Hope I'm not losing you, Mike Williams had said the same thing really.
