Detailed Description

Holds onto memory re-used by rt_shootray() from shot to shot. One of these for each solid which uses pieces. There is a separate array of these for each cpu. Storage for the bit vectors is pre-allocated at prep time. The array is subscripted by st_piecestate_num. The bit vector is subscripted by values found in rt_piecelist pieces[].
