total refactoring of the texture restoration process on a context loss

You can now restore a texture using a "onRestore" callback function. The default behaviour is still to keep the original bitmap data around for the restoration, but you're able to override this by creating your own restoration mechanism -- which might reload the file from disk, recreate it from an Embedded Bitmap, etc.
