Re: Unified draft of SVG-in-OT

Whether authors may want it isn't the issue – the fact is that it would completely inappropriate to have a glyph that is placed at at a specific location on a page drawing outside it's given "box" - not just slightly, but even worse, somewhere completely different.

If you don't clip – what is to prevent a glyph from doing its own translate transform and ending up somewhere else on the canvas/page?!?!

It is extremely important that the bounding box for the normal glyph be 100% identical to that of the SVG variant, and that all drawing is clipped to that box – just as it is with normal rendering.

One more thing: although the same bounding box is used for layout whether or not SVG glyphs are rendered, when SVG glyphs are rendered we do NOT clip to that box. That's hardly ever what authors would want, and there's no need to do it.
