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