The layout marks a glyph synth_bold when Faux Bold is on, or when a bold
style is asked of a family without a bold face, but the renderer never
read it, so both drew as regular.

PlacedGlyph now carries the bold radius (0.03 em, which brings Inter
Regular's stems to Inter Bold's). A bold fill is the outline's coverage
merged with a round stroke twice that wide, and a bold glyph's stroke is
the band between the outline grown by radius ± half the stroke width, so
it follows the bolder shape. Runs of solid fills only merge glyphs of the
same bold radius, and the patch and layer bounds grow by it.
