Enabling color and depth channels on a Frame inconsistent with Spec

[Kevin Griffin]

The enabling of the color and depth channels on a Frame is inconsistent with the spec. Setting the observable type of the aforementioned channels is supposed to be sufficient for enabling those channels. e.g.,

anari::setParameter(anariDevice, anariFrame, "color", ANARI_UFIXED8_RGBA_SRGB);
anari::setParameter(anariDevice, anariFrame, "depth", ANARI_FLOAT32);

However, if you don't also set two additional parameters on the Frame, channelColor and channelDepth, to true the color and depth channels won't be enabled. Also, the channelColor and channelDepth parameters are not documented in the spec.

This is now fixed in main, thanks!
