figurememory(h)

Estimates memory usage of figures

Returns an approximate number of bytes of memory used by a figure (or other graphics object) and its descendants
Basically provides the equivalent of whos for graphics objects. Useful if you have a figure that is consuming a lot
of memory. Operates by finding all descendants of the graphics object and summing up the bytes consumed by each of the major data entries (XData, YData, ... AlphaData, RData, ThetaData).
