* NOTES -- PC version
*
* A sprite consists in 4 columns and 0x15 rows of (U16 mask, U16 pict),
* each pair representing 8 pixels (cga encoding, two bits per pixels).
* Sprites are stored in 'sprites.bin' and are loaded by spr_init. Memory
* is freed by spr_shutdown.
*
* There are four sprites planes. Plane 0 is the raw content of 'sprites.bin',
* and planes 1, 2 and 3 contain copies of plane 0 with all sprites shifted
* 2, 4 and 6 pixels to the right.
