Subject: Makes FontData importable resource. Adds multi-channel SDF font
 texture generation and rendering support. Adds per-font oversampling support.
 Adds FontData import plugins (for dynamic fonts, BMFonts and monospaced image
 fonts), font texture cache pre-generation and loading. Adds BMFont binary
 format and outline support.
