Re: Unified draft of SVG-in-OT

We are talking about the glyph bounding box, which defines the height, width etc. for the glyph  which is most certainly used by any layout engine to know where to place the next glyph in a text run, as well as related glyphs.

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.

If you were to allow the SVG variant of the glyph to be sized differently  it would be IMPOSSIBLE to maintain a consistent layout of content between systems that differed in which of the variants was selected.   And I am pretty sure none of us want that.

We're talking about ink bounding box, right?

Ink bounding boxes generally don't affect layout. At least not in Web browsers.
