Remarks

This class in the base class for the texture cache (texture manager). Sub-classes from this class should implement their functionality by implementing the virtual functions using the the selected graphics API. 
Use the flyEngine init_texture_cache and free_texture_cache to initialize and free the global variable tc that is the main interface to this class.
