ShowLayer(id[, x, y])
id. You can hide
layers and layer groups by calling HideLayer().
You need to enable layers before you can use this function. See Layers introduction for details.
Starting with Hollywood 2.0 there are two optional arguments x and y.
You can use these two arguments to re-position the specified layer.
So you can move a layer to a new position using this function. Both
arguments default to #USELAYERPOSITION which means that the layer will
not be moved if you do not specify these arguments.
