"""Tileset and font related functions.

If you want to load a tileset from a common tileset image then you only need :any:`tcod.tileset.load_tilesheet`.

Tilesets can be loaded as a whole from tile-sheets or True-Type fonts,

or they can be put together from multiple tile images by loading them separately using :any:`Tileset.__setitem__`.

A major restriction with libtcod is that all tiles must be the same size and tiles can't overlap when rendered.

For sprite-based rendering it can be useful to use `an alternative library for graphics rendering

<https://wiki.python.org/moin/PythonGameLibraries>`_ while continuing to use

python-tcod's pathfinding and field-of-view algorithms.
