SVG Paint and CSS Images

• Resolved: Tab to add wording to CSS Image Values 4 about how SVG Paint Servers apply to CSS.
• Resolved: Tab to draft something about how CSS image values apply to SVG. This will live in the CSS Image values 4 spec for now (it may move later).
• Resolved: The new image generator methods (eg. turbulence) to be added to CSS Image Values 4
• Some concern about restraining scope / keeping syntax sane for the new
  image generator methods.

Hit Testing and Transparency, pointer-events

• Resolved: List all the current values for pointer events, everything other than none is treated as auto unless applied to SVG content
• Resolved: Add an author conformance criteria saying that they should not use the other pointer-events values outside of SVG
