-		DynamicFont renders vector font files (such as TTF or OTF) dynamically at runtime instead of using a prerendered texture atlas like [BitmapFont]. This trades the faster loading time of [BitmapFont]s for the ability to change font parameters like size and spacing during runtime. [DynamicFontData] is used for referencing the font file paths.

DynamicFont also supports defining one or more fallbacks fonts, which will be used when displaying a character not supported by the main font.
