Sets the default texture color.

The default texture color is used when loading textures from
urls. Because the URL will be loaded async we'd like to be
able to use the texture immediately. By putting a 1x1 pixel
color in the texture we can start using the texture before
the URL has loaded.

@param {number[]} color Array of 4 values in the range 0 to 1
