-// Theory:
-
-// Stage 1:
-// Only performed when text mask changes.
-// Update glyph cache with every glyph used in the title.
-// A parallel text renderer draws one character per CPU.
-// The titler direct copies all the text currently visible onto the text mask.
-// in integer coordinates.
-// The text mask is in the same color space as the output but always has
-// an alpha channel.
-
-// Stage 2:
-// Performed every frame.
-// The text mask is overlayed with fractional translation and fading on the output.
