Now let's find an image to use as a texture in the game.

A `texture` contains the underlying Java object. By default, it will be drawn at the bottom-left corner with the size of the image itself. You can change the position and size by simply using `assoc`: A `texture` contains the underlying Java object.

You can also set scaling and rotation on a texture using :scale-x, :scale-y, and :angle, which all use (:origin-x, :origin-y) as the center. For example, here we rotate it 45 degrees counter-clockwise around the bottom-left corner: You can also set scaling and rotation on a texture using :scale-x, :scale-y, and :angle, which all use (:origin-x, :origin-y) as the center.
