[postgis-devel] postgis_letters in project tree?

[Paul Ramsey]

Added some extra magic to tighten up the kerning to pack short letters tighter under tall narrow letters like T and Y. OK, I'll stop now!

ST_GeomFromLetter can be expanded over time to include additional letters for other language charsets. That matches the capabilities of the system to the needs.
