|Enhanced lvl 1 text, which uses preconditioned font data.
|Uses same data as kEnh1 but applies extra anti-aliasing; slower than kEnh1.
|Uses the same data as kEnh1 with a less accurate but faster shader.
|Enhanced lvl 2 text, which uses different preconditioned data than kEnh1.
|Like kStd, but still in development. Experimental -- never for production use.
|Fastest rendering, but the text quality is unacceptable for most use cases.
|Standard quality, which is ideal for on-the-fly font loading.
|N.B. these are still in development and deprecated; prefer kStd except for testing purposes.
