Provide multiple layer-names (stacking is done from left to right), e.g.:
>>> m.show_layer("A", "B", "C")
Provide the combined layer-name, e.g.:
>>> m.show_layer("A|B|C")
To transparently overlay multiple layers, use one of the following options:
Provide tuples of layer-names and transparency-assignments, e.g.:
>>> m.show_layer("A", ("B", 0.5), ("C", 0.25))
Provide the combined layer-name, e.g.:
>>> m.show_layer("A|B{0.5}|C{0.25}")
