31 tile.{h,cpp}: Texture handling stuff.
35 Gets the path to a texture by first checking if the texture exists
36 in texture_path and if not, using the data path.
38 Checks all supported extensions by replacing the original extension.
40 If not found, returns "".
42 Utilizes a thread-safe cache.
44 std::string getTexturePath(const std::string &filename);
47 Specifies a texture in an atlas.
49 This is used to specify single textures also.
51 This has been designed to be small enough to be thrown around a lot.
