Basically, you are correct. However, there exist fonts (in particular
for CJK scripts) that give correct results only if hinted, since
subglyphs get scaled and moved with bytecode instructions. Within
FreeType, such fonts are called `tricky'. A solution for such fonts
is to scale them at size of ppem pixels, e.g. 2048px for most TrueType
fonts, but you probably don't need this.
