Now that there are two distinct types of image spans: plain ``ImageSpan``s and ``PageImageSpan``s, it is not easy to get the entire image that the current span is a subset of, as ``PageImageSpan``s require different treatment. This is not good.
This PEG resolves the problem by adding a method to ImageSpan to get the entire 2D image the current span is a subset of.
The name for the new method? We need to say it's the opposite of a subimage, or somehow express that it's a larger area.
RESOLVED: getSuperImageSpan. It's not perfect but at least it expresses that.
Into ImageSpan add the method getSuperImageSpan:
/** Get the whole contiguous 2D image that this span is a part of. */ ImageSpan getSuperImageSpan();
