setToTileTransform

Sets this matrix to one that transforms normalized coordinates from a source sector to a destination sector. Normalized coordinates within a sector range from 0 to 1, with (0, 0) indicating the lower left corner and (1, 1) indicating the upper right. The resultant matrix maps a normalized source coordinate (X, Y) to its corresponding normalized destination coordinate (X', Y').
This matrix typically necessary to transform texture coordinates from one geographic region to another. For example, the texture coordinates for a terrain tile spanning one region must be transformed to coordinates appropriate for an image tile spanning a potentially different region.
