Detailed Description

This structure caches information about rendering a text in one font wrapped to a specific width. It points to structures in the chunkCache that cache detailed information and the textures used.

Note

Caching text-wrapping information is particularly important for Cyrillic and possibly other non-ascii text, where TTF_SizeUTF8() is almost as slow as rendering. Intro sequence went from 4 fps to 50 after introducing the wrapCache.
