[autofit] Fix double division in stem darkening. The old code used to divide the darkening amount by em_ratio twice, leading to unnecessarily bold stems on certain fonts with higher units per em (e.g. Inter). This patch fixes it. The return value of af_loader_compute_darkening was also changed to use 16.16 fixed point to get rid of a redundant truncation operation. This should slightly improve the precision, although it's still bottlenecked by the emboldening function, which uses 26.6 fixed point. * src/autofit/afloader.[ch] (af_loader_compute_darkening): Return FT_Fixed. (af_loader_embolden_glyph_in_slot): Revise calculations.
