/**
* Load a BufferedImage array into a texture array.
* <p>
* Each BufferedImage must be of type BufferedImage.TYPE_4BYTE_ABGR. The
* images will be loaded at 0,0 at each level of the texture array.
* <p>
* It appears that the images must have a row length that is a multiple of
* four. This is probably due to the particular format we're using, and
* could probably be worked around, but the simple fix is to check your row
* length.
*
* @param gl the current OpenGL context.
* @param textureName The name of the texture to bind to with BindTexture().
* @param images A List of BufferedImages of type
* BufferedImage.TYPE_4BYTE_ABGR.
* @param maxWidth The maximum width of the images.
* @param maxHeight The maximum height of the images.
* @param minFilter Texture selection with TEXTURE_MIN_FILTER.
