### `ui_piece_get_cell(int pid, int rot, int which)`
Gets one cell of a piece: `pid` is the piece number, `rot` the rotation and `which` the cell index.
```c
ui_piece_get_cell(0, 0, 3);   /* piece 0, no rotation, cell 3 */
```
### `ui_piece_init(void)`
Initializes the piece tile table (the no-argument version; see `Lib/shared/src/vmlui.c` for the exact shape).
```c
ui_piece_init();
```
