Create a cursor using the specified data and mask (in MSB format). +The cursor width must be a multiple of 8 bits.
The cursor is created in black and white according to the following: +
| Data / Mask | Resulting pixel on screen |
|---|---|
| 0 / 1 | White |
| 1 / 1 | Black |
| 0 / 0 | Transparent |
| 1 / 0 | Inverted color if possible, black if not. |
Cursors created with this function must be freed with +SDL_FreeCursor.
