In Qt port we have GlyphBufferAdvance based on point type, not size type, however this code seems to work equally well with both point- and size-based GlyphBufferAdvance.

I think it's bad that these platform types propagate around masquerading as cross-platform types.
If you are interested in this kind of patches, could you help me with SVGGlyphToPathTranslator::extents (rendering/svg/SVGTextRunRenderingContext.cpp)?
It has similar issue: mapSize is used to convert width of GlyphBufferAdvance, which is converted to FloatSize for this purpose.
