Summary consider removing support for removed SVG properties
Cameron McCormack (:heycam)
Reported 2021-07-12 23:31:33 PDT
There are four properties that were removed from the SVG 2 spec, and which are not supported in other browsers: * color-profile -- we recognize the property but don't do anything with it * color-rendering -- we parse and expose this but don't do anything else with it * glyph-orientation-horizontal -- we do use this in our SVG text layout * kerning -- we do use this too in our SVG text layout Don't see why we shouldn't remove the first two, and we should probably try to remove the second two as well. (The text-orientation and letter-spacing properties are the official replacements for glyph-orientation-horizontal and kerning.)

Also, glyph-orientation-vertical is deprecated, but still is in the spec. But WebKit is the only engine to implement it too.

Relatedly, enable-background is another one that was removed (though from the Filters spec), and which we recognize but don't do anything with.

This seems reasonable to me for color-profile, color-rendering and enable-background.

Once this patch lands, please file a separate bug for the other properties I mentioned that we should try to remove.
