[svgwg] new commits pushed by svgeesus

The following commits were just pushed by svgeesus to https://github.com/w3c/svgwg:

* No normative appendices! (#548)

* Move normative parts of implnote.html to chapters

Section "Error Processing":

- moved to the end of the "Document Conformance Classes"
  (in conform.html)
- passive-voiced "shall" commands rewritten
  as requirements on user agents
- the example of a general error rewritten to refer
  to the document conformance requirements
- it's made explicit that these general error processing
  rules can be overridden by more specific rules
  elsewhere in the spec.

Section "Clamping values which are restricted to a particular range":

- moved to types.html (Basic Data Types and Interfaces chapter)
- paragraphs re color and opacity removed,
  since clamping behavior of those properties is defined in CSS Color
- remaining paragraph generalized, with clarifications that
  * it only applies if more specific rules aren't given elsewhere
  * it applies to clamping for device capabilities as well as per spec

Section "Elliptical Arc Implementation Notes":

- the normative section on out-of-range parameters
  is moved to the Paths chapter implementation notes.
- the syntax is updated to use parameter names defined in the chapter,
  not the mathematical notation defined in the appendix
- the remaining sections on arc parameterization and conversion
  are tidied up to stand alone in the appendix
- Equation numbering is made independent of
  Appendix/section numbering (which was no longer correct).

The rest of the "Implementation Notes" section is paths.html
is reorganized into logical sections.
The contradictory statement that
"A non-positive radius value is an error."
 is removed.
(Elsewhere, the spec says to use the absolute value of negative radii,
and most browser implementations match; see #324.)

Section "Text selection implementation notes":

- moved to the end of the "Text selection and clipboard operations"
  section (in text.html)

Section "Printing implementation notes":

- moved to the end of "Conforming SVG Viewers" section (in conform.html)

Cross-references to these sections have also been updated.

Changes appendix entries have been made.
Links to PR will need to be updated once a PR is generated.

* Update dependencies in SVG DOM appendix

- Clarify which software the "SVG DOM requires" statements apply to
  (viewers/interpreters with scripting support).
- Make DOM 4 a minimum requirement, with DOM living standard a "should".
  Note: W3C DOM 4 isn't currently listed in the refs.
  Would it be better to make the minimum requirement a timepoint
  in the DOM LS history?
- Remove requirement for support of obsolete DOM View spec.
- Update the requirement on DOM Level 2 Style to
  only include interfaces also defined in CSSOM,
  with full support for CSSOM as a "should"
  (CSSOM is still WD, but it drops a lot of DOM Style
  that was never implemented.
  Alternative would be to list which DOM2 Style interfaces to support.)
  DOM Level 2 is included as an informative reference
- Remove the "Relationship with DOM Level 2 CSS" section.
- Add Geometry Interfaces Module Level 1 as a normative ref,
  since it didn't seem to be included anywhere
  (despite being referenced in many WebIDL dependencies).

Also: fix some alphabetization issues in refs.html. Add changes entries.

* Reorganize SVGDOM content re initializing values

In prep for moving the content to the Types chapter.

- Separate out overview paragraphs on reflecting attributes
  from specifics on initializing objects to `(none)` initial values.
- Rename the section on initialization to clarify when it applies,
  and add new intro paragraph.
- Make it clear that the rules for initializing compound interfaces
  are not restricted to those defined in SVG.
  (Reintroduce example of DOMRect &
  include other numeric primitive numeric types in initialization list.)
- Remove the special rule about `SVGTextContentElement::textLength`
  in this section, and replace it with:
  * clearer text defining the initial value of the content attribute
  * a note in the IDL definition explaining the impact
    of the dynamic initial value
- Use proper example formatting for the "for example"
  paragraph, add links/clarification,
  and add a matching example of initializing a `(none)` value.

* More updating of SVGDOM appendix

Section "Elements in the SVG DOM":

- Add a preamble paragraph to clarify normative requirements.
- Make it clear that the rule applies to SVG-namespaced elements
  defined in other specifications (e.g., filters, masking).
- Add a requirement for handling unknown elements.
  (Should implement SVGUnknownElement;
  must implement SVGElement, since that's what browsers do.)
- Add a warning about SVGUnknownElement being at-risk.
- Mark up the "for example" as a proper example.

Section "Naming Conventions":

- Make the naming conventions section reference modern DOM + HTML,
  and remove the informative reference to DOM Level 1.
- Add a paragraph on the naming conventions of interfaces.
- Remove mention of (long-since-removed) CDATA type;
  Case preservation when reflecting strings is already covered
  by the rules in HTML about reflecting basic types.
  (and either way, that's not part of Naming Conventions!)

Section "Invalid Values":

- Clarify that this applies to reflected attributes
  & validity restrictions on the content attributes.
- Add a link to Github Issue #547, re matching reality.

* Update UI Events section in SVGDOM appendix

In preparation for merging into the interactivity chapter.

- Add a normative reference to the Clipboard API spec,
  since we're including event handlers for the events it defines.
- Add normative wording about which events need to be implemented
  (with exceptions for non interactive environments,
  and an exclusion for the legacy events defined in UI Events spec).
- Clarify that most onEvent attributes/properties
  are available on all elements in the SVG namespace.
- remove statements and example
  about onclick, etc. attributes
  only being valid on certain elements.
- Keep the general rule about event attributes not working
  where invalid
  (since it applies to & is implemented for onbegin, onend, etc.)
  But remove statements about addEventListener working,
  because those events don't support addEventListener,
  per the table in https://svgwg.org/svg2-draft/interact.html#SVGEvents
- Remove a cross-reference to the deleted paragraph from pservers.html
- Mark up the example as such.

* Move SVGDOM appendix content to chapters

And re-arrange some content to match.
With additional edits only when required for
merge conflicts with existing content.

In types.html:

- #SVGDOMOverview is now a major section in types.html,
  with the following subsections taken from svgdom.html and
  from the length intro to
  types.html#DOMInterfacesForReflectingSVGAttributes
  * Dependencies (new heading for content from svgdom.html)
  * Naming conventions (from svgdom.html)
  * Elements in the SVG DOM (from svgdom.html)
  * Reflecting content attributes in the DOM (merging intros,
    with a little extra effort to actually define the term "reflect")
  * Synchronizing reflected values
    (new heading on content from types.html)
  * Reflecting an empty initial value (from svgdom.html)
  * Invalid values (from svgdom.html)
- Without its intro section on what reflecting attributes means,
  the major section for DOM interfaces that reflect attributes
  is renamed to clarify these are the *Animated* interfaces,
  with a brief intro about the baseVal/animVal structure.
- The one non-animated interface in that section
  (SVGStringList) is moved up to the previous section.
- Elsewhere in types.html, the short sections on
  number precision and clamping are made sub-sections
  to the attribute syntax.

In interact.html:

- The "Relationship with UI Events" section is inserted as a sub-section
  to "Supported Events" except:
- The paragraphs about possible implementation of event attributes,
  and the example of their use, is added at the end of the
  "Event attributes" section.
- A mention of that section as being in another chapter is removed.

svgdom.html, with its content removed, is turned into a stub file
(and publish.xml updated accordingly)

Cross-references are updated in other files.

Changes section is updated
(including some updates that should have been on the last commit).
