Prezi 4 minor issues from read through

[azaroth42]

• Update description of UC6 in the top block to refer to chessboard
• Update UC7 to have a use case, both at top and in Nesting Containers section
• Rename UC8 to be "Commenting on Specific Features" at top and section heading (the 'painting' as target isn't the UC, it's just an example along with sculpture and the whale)
• @glenrobson to make the little arrow for backticked features more obviously a 'this is a link'
• "The defined Container types are:" looks abandoned in HTML. Replace with "... are defined below" ; Same for "Scenes use several 3D specific constructions to manage rendering:" under Scene
• Under Scene, there's the wikipedia image with "(Image: Wikipedia)" which should at least link to the WP page
• Lights section has broken internal links
• TODO: JSON examples for Anno, Anno Page and Anno Coll’n ?
• Annotation Page talks about z-index, but should do so /only/ in terms of Canvas I think with reference to Scenes having explicit Z.
• In Containers as Content Resources: "This capability is described further in the [Nesting Containers] section."
• Broken internal links in Specific Resource section for selector and scope
• Transforms: the subclasses aren't linked
• Need to replace the spaceman image in 6.2 with a pawn
• Key Points for UC6 are missing the styling
• Scene into Scene -- starts off with "Like Timelines or Canvases..." but we haven't talked about painting them into scenes yet in this order.
• UC7 needs a lot of work still. Can we just drop UC7 completely and talk about it along with the nested Scenes?
• The sequence behavior looks strange as a heading. Drop backticks and replace with ""?
• Accessibility as a top level heading is hard to distinguish from Additional Features in the ToC styling
• In model/ need to write the Registry section (or drop it?)

In the model, Claude noted a discrepancy between lookAt values description vs properties list, line 1904 vs. 1910.
