	* GraphicsCache.C: Changed to use shared_ptr<GraphicsCacheItem>
	instead of a pure pointer.

	* GraphicsCacheItem.[Ch]:
	* GraphicsCacheItem_pimpl.[Ch]: Collapsed them into GraphicsCacheItem,
	removed the reference counting that was inside. Also fixed a bug where
	a temporary file wouldn't get erased.

	* ImageLoader.[Ch]: Changed the semantics of the image_ pointers usage.
	Ownership is now dropped when the caller requests the image_ pointer.

	* GraphicsCache.C: Cleared up the confusion on when and how it is
	emptied.

	* GraphicsCacheItem.C: Indentation change.

	* GraphicsCacheItem_pimpl.C: Fixed the loading logic so that it will
	figure correctly when the image has been loaded successfully.

	* ImageLoader.C: add a "using" directive.

	* ImageLoader.h: remove extra comma at the end of enum; add an
	std:: qualifier for vector.

	* GraphicsCacheItem.[Ch]: Changes due to the storage of width and
	height in the image itself and minor cleanups.

	* GraphicsCacheItem_impl.[Ch]: Changes due to the switch to use a
	new ImageLoader class instead of the older Renderer class. This
	means change of responsibilities.
