Sometimes it may be advantageous not to store lot's of images on disk but to pack everything into one big image(8k x 8k) and load only a small part of it. For example, this feature can be useful for storing land textures.

So it would be nice to have Ogre::Image::load( const Ogre::String& file, const Ogre::TRect& rect ) method.
