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