Hi,
attached is my attempt at creating a testcase showing that altGlyph is not
working for non-SVG font formats.
To the best of my knowledge this has not been implemented in any
viewer/browser. I've tested this in Firefox Nightly, Chrome Canary and
Opera 12 (Presto) and none of them found the proper altGlyph. I haven't
tested it in IE yet, but I suspect that it will fail there too, especially
given that the documentation says altGlyph isn't supported[3].
Given that we have already removed SVG Fonts from SVG2 and given that
altGlyph is effectively useless without SVG Fonts, I'd like to propose
that we also drop altGlyph, altGlyphDef, altGlyphItem and glyphRef from
SVG2. Thoughts?
