Access the data from this data block.
If the data block is constant, getData will return a pointer to a single texel's data value.
If the data block is tiled, then getData will return null and the data must be accessed per-tile via the getTile() function.

Read a single texel from the data block.
The texel coordinates, u and v, have a range of [0..ures-1, 0..vres-1]. Note: this method will work correctly even if the face is constant or tiled.
