I don't see much need at the moment for IRE.  IRE isn't going to be
useful for general graphics rotation as it only supports up to 16bpp

It looks to me like this module was designed to rotate YUV/camera
images.  If we wanted to rotate a video image, then it would probably
be more efficient to use this, but it will cause a conversion of the
image format in doing so.
