@wipfli Hey. Thanks. This technique, like most GPU-accelerated text rasterizers, render "linearly-scalable" text, which means you don't do any hinting of the glyph shapes for the size they are displayed in, which means blurry and imperfect text at small sizes. For UI small-size text, still you need something like FreeType which does hinting, but then you can't freely scale and rotate the text on the fly. The linear algorithms are useful for games, virtual reality, etc, where fast, arbitrary transformations, are required.
