Sets the wrapping properties of an Image.

This function sets the way an Image is repeated when it is drawn with a Quad that is larger than the image's extent. An image may be clamped or set to repeat in both horizontal and vertical directions. Clamped images appear only once, but repeated ones repeat as many times as there is room in the Quad.

N.B. If you use a Quad that is larger than the image extent and do not use repeated tiling, there may be an unwanted visual effect of the image stretching all the way to fill the Quad. If this is the case, setting Image:getWrap("repeat", "repeat") for all the images to be repeated, and using Quads of appropriate size will result in the best visual appearance.

O.png This is a feature of the graphics card, it will work everywhere, but not always the same, namely, if the image is not PO2, the results will be different for people that don't support it.
