// 4.3.2001 mcn - Created. //
// 5.3.2001 mcn - Completely revamped. Now plDrawableSpans *IS* the group //
// of spans, and each span is either an icicle or patch. //
// This eliminates the need entirely for separate drawables,//
// at the cost of having to do a bit of extra work to //
// maintain different types of spans in the same drawable. //

// Here's the problem. When we update one of the matrices in the matrix palette,
// we've invalidated the current bounds of all the spans that use it. The skinning
// matrix may have moved the spans, or may just have stretched them, but either
// way, they aren't right any more. Wait, it gets worse. We're going to have a bunch
// of SetTransform calls come in, and then some time later, without our knowledge,
// our bounds (via the space tree and PageTreeMgr) will be used to evaluate whether
// to bother drawing us. Clearly, if we're going to keep our bounds up to date, we
// want to wait until all the SetTransforms have come in, and then update our bounds
// all at once, but before the visibility determination phase kicks in.
// The alternative is to make the local bounds conservative. We bloat out the local
// bounds on export so that whereever the skinning matrices push us around, we're
// still inside the local bounds. This is certainly cheaper to compute (all computation
// is offline), but gives a less tight bounds. Whether the conservative bounds is
// tight enough will depend on how the skinning is actually being used.
//
// Therefore I'm deferring decision on which way to go, and putting in this temp hack
// which does it the dumbest way possible while still being correct.
//
// So recap:
// If we need tight up-to-date bounds, we'll probably send a system message between
// the update phase (Eval Msg) and the render phase, only marking as dirty the changed
// palette matrices.
// If conservative bounds are good enough, we'll need to compute those from the skinning
// animations offline.
