example1

rendering fonts (especially at normal 10-18px sizes) appear very bad when scaled, like when doing cairo_scale(cairo, 0.5, 1.0)

The problem seems to be the glyphs are individually scaled, and then laid out as (almost) normal. The result is much worse compared to rendering the text normal and then scaling it back.

see attachments how more pixels are inserted when rendering scaled
