Second Sync Update

[DRx3D]

The models added here need some assistance - mostly descriptions. This is meant to be applied after PR #85 and after the 'issues' tag has been removed.

The new models in this PR are:

1. ClearcoatRing
2. ClearcoatSphere
3. SheenHighHeel
4. SuzanneMorphSparse
5. TransmissionSuzanne

In addition other models may have had various updates to READMEs to improve the formatting.

All of the models listed in this PR all need descriptions. Most were supplied by UX3D. Tagging a few UX3D people to attract their attention. The model description can be added as a comment and I will get it into the system. You can also create a PR against the forked branch if it is a substantial change.

@javagl, @lexaknyazev : The SuzanneMorphSparse model needs a description. Can either of you provide something simple for this?

[javagl]

Maybe this was already supposed to be reviewed, and I missed it, but I'd suggest to not include SuzanneMorphSparse in its current form.

• It claims to use KHR_materials_unlit and KHR_texture_transform but uses neither of these
• It contains some undocumented/useless extras
• It contains a node that has rotation/translation/scale set, but all with their default values
• Most importantly: It does not contain any morph animation.

I don't know where the screenshot GIF comes from, but none of the common viewers that I tried shows anything "animated" there. (That small white thing that appears (in the GIF) in the lower left when the eyes are closed are a minor detail at this point...)

I know that this means that #61 will remain open, but... that's what it is for now.

It contains some undocumented/useless extras

Those are actually spec-suggested, see the note at the end of the Morph Targets spec section. Agreed with all other points.

There's also inconsistent indentation in SuzanneMorphSparse/metadata.json.
