Textures come from files inside of a "textures" folder. If the file is square (has equal width
and height dimensions), it is scaled down to 16 x 16 pixels. Non-square images are used with animated
textures. In this case, the first frame of the animated texture is used, and also scaled to a 16 by 16 image.
