+Updated Figure.savefig()
+------------------------
+
+Added support to save the figure with the same dpi as the figure on the screen using dpi='figure'
+
+Example:
+	f = plt.figure(dpi=25)				# dpi set to 25
+	S = plt.scatter([1,2,3],[4,5,6])
+	f.savefig('output.png', dpi='figure')	# output savefig dpi set to 25 (same as figure)
