* - for uncompressed images, we could do direct mapping of the input
* - perhaps we could stream compressed images? but only if ext is defined at
* the start of the file
* (yes, file format is magic number, 348-byte header, extension data,
* pixel data, then all gz'd)
* - we could use the much faster byteswap in glib?
* - I have not been able to test the ext stuff :(
