When viewing the tile map, use pinch controls to zoom and directional drag to translate position of the map.

I'm thinking:

Single touchpoint: translate main display group (within x & y bounds)
Double touchpoint: initial length of the line segment between the two points is the base scale. Increasing or decreasing the length of the line will directly transpose to the delta to the scale factor of the main display group (again, within bounds). The x and y delta of the center of the line segment will also be translated to the main display group.
