annotate mde/scheduler/init2.d @ 48:a98ffb64f066

Implemented font rendering (grayscale only; i.e. non-LCD). FontTexture creates a texture and caches glyphs. Font supports multiple styles/faces, loaded from config file (should probably be loaded via Options instead). TextBlock cache for glyph placement within a string. committer: Diggory Hardy <diggory.hardy@gmail.com>
