Freetype<2.8.1 v40 has the wrong advance width issue and wrong rendering issue.
This workaround is required for the Linux distribution that contains the old
version of Freetype.
I was trying to submit it together because it was related to other FreeType
issues. However, since this patch alone is meaningful, I submit it separately.
