Set the vertical advance of glyph metrics to zero.
Set the vertical advance of glyph metrics to zero.

The OpenVG paint engine uses this value as the escapement of the glyph

out in a declining staircase fashion. All other font engines seem to
set the vertical advance to zero so do the same here as well.
