BUG? Channels with 0 will fallback to red value

[krister-ts]

        const g = normalizeValue(typedBuffer[j + 1] || r, datatype, typeSize, maxV, minV);
        const b = normalizeValue(typedBuffer[j + 2] || r, datatype, typeSize, maxV, minV);

These fallbacks in panel.js cause problems rendering colors when a channel has value of zero. Could this be removed or changed to only fallback when green and blue are both zero??

Thanks

I think the or case should be removed entirely. If any value is zero, it should use that only. I'll get onto it right now.
