// killough 1/19/98: rewritten to use to use a better random number generator
// in the new engine, although the old one is available for compatibility.
// killough 2/16/98:
//
// Make every random number generator local to each control-equivalent block.
// Critical for demo sync. Changing the order of this list breaks all previous
// versions' demos. The random number generators are made local to reduce the
// chances of sync problems. In Doom, if a single random number generator call
// was off, it would mess up all random number generators. This reduces the
// chances of it happening by making each RNG local to a control flow block.
//
// Notes to developers: if you want to reduce your demo sync hassles, follow
// this rule: for each call to P_Random you add, add a new class to the enum
// type below for each block of code which calls P_Random. If two calls to
// P_Random are not in "control-equivalent blocks", i.e. there are any cases
// where one is executed, and the other is not, put them in separate classes.
//
// Keep all current entries in this list the same, and in the order
// indicated by the #'s, because they're critical for preserving demo
// sync. Do not remove entries simply because they become unused later.
