+- `u` (type: `integer`, optional): the `X` coordinate of the upper left corner in the texture file, in real pixels (defaults to 0)
+- `v` (type: `integer`, optional): the `Y` coordinate of the upper left corner in the texture file, in real pixels (defaults to 0)
+- `textureWidth` (type: `integer`, optional): the actual width of the texture file, in real pixels (defaults to `width`)
