Positioning Controls on the Map

Is there an option somewhere that lets us specify the position of the Zoom control on our map (also applies to other controls such as the map scale and map types controls)? Can't find any in the settings options or documentation that describes how to do this. Is this something that can be achieved through a theme override (theme_gmap) or in a custom module using hook_gmap? Are we stuck with the default position of G_ANCHOR_TOP_LEFT, or is there a way to optionally specify a different value for our map?

According to the Google Maps API documentation, the "addControl method takes an optional second GControlPosition parameter that lets you specify the position of the control on your map. This value can be one of the following values, each specifying a corner of the map in which to place the control:

G_ANCHOR_TOP_RIGHT
G_ANCHOR_TOP_LEFT
G_ANCHOR_BOTTOM_RIGHT
G_ANCHOR_BOTTOM_LEFT"
