I tested it, and the rasterizer output is almost identical.
Curiously, for this font, the dense rasterizer is faster even till 200-300 ppem font \
size
This is definitely because smooth is constrained by memory and has to restart (see \
longjmp) with narrower bands to handle the job. It looks like one restart for each \
glyph approximately.
Relevant files attached.
Do you mind continuing this discussion as an issue on GitLab?
