Gets a single tile from a dataset.

The tsmReadTile function retrieves a single tile from the dataset with a tile index ( tx, ty, level ). The buffer memory is assumed to be sufficiently large to hold the entire tile. N.B. This function is NOT recommended when accessing mulitple tiles from a DPSS because it has all the overhead of building and transmitting a request list for each tile. Instead, use the request list mechanism.

You can set the TSM_DONT_READ_TILES setting to TRUE using tsmSet and this function will perform no disk or network access. This may be useful for assessing your application's computational overhead.
