TileController::blankPixelCountForTiles calculates its result as a uint64_t, but returns it as an unsigned. The former is a 64-bit value, while the latter can be a 32-bit value on some platforms. This mismatch can lead to a compile-time error. Fix this by explicitly casting the 64-bit value to a "signed".
