Add SVG 1.1 variants of presentation attribute values

[noahbald]

Hey there, I've noticed the following property are missing some values that are expected for SVG 1.1

• text-rendering is missing "geometricPrecision"
• shape-rendering is missing "crispEdges" and "geometricPrecision"
• color-interpolation is missing "linearRGB"
• display is missing "marker" and "compact"
• font-family won't parse quoted names (e.g. 'Arial Unicode MS')

There may be some more while I'm still investigating

I can make a PR for these if these changes are wanted

Sounds good. A PR would be welcome.

Seems like display: marker and display: compact were only ever experimental/draft properties, so I won't include those
