With this commit, I’m seeing one pixel differences in my test suit,
things like (with Amiri):

expected:  [uni06DD+2620|one.small at -2210,0+0|two.small at -1610,0+0|three.small at -1010,0+0]
result:    [uni06DD+2620|one.small at -2209,0+1|two.small at -1609,0+1|three.small at -1009,0+1]

Looks harmless, but wanted to double check before updating the expected
output.
