// plDrawableSpans Header // |
|
// // |
|
// The base plDrawable derivative for ice (triangle list) // |
|
// drawables. Contains the basic structure for spans and the functions // |
|
// to deal with them. // |
|
// // |
|
//// Version History ///////////////////////////////////////////////////////// |
|
// // |
|
// 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. // |
|
// 4.20.2006 bob - Patches are long gone. Only icicle (or particle) spans // |
|
// now. |
|
// // |
