| 2698 | 521 let S be the actual sprite's width (like, 32 pixels for example) |
| 522 let R be the rectangle's width (maybe 50 pixels) | |
| 523 HDX = (R<<8) / S; | |
| 524 (it's fixed point, hence the bit shift. same goes for vertical. | |
| 525 be sure to use 32-bit int's for the bit shift before the division!) | |
