bryner%netscape.com	d96798d50e	Get rid of gcc3's numerous warnings about using <new.h> instead of <new> by creating a new #define, NEW_H, which should be used instead of <new.h> or <new>. This is so we can continue to support a couple of braindead compilers that don't accept <new>. Bug 155852, r=cls.	2002-08-19 03:50:27 +00:00
dbaron%fas.harvard.edu	75d32bb579	Bug 86947: ... Make the line list doubly linked and access it through a list class and iterators. Stop recomputing margins on all of the children of each block in the reflow chain (which causes O(N^2) state recovery during incremental reflow). Instead, add a second dirty bit to the lines and walk backwards through the line list to recompute vertical margins only when either dirty bit is set and the previous line was not reflowed. Add nsIFrame::IsEmpty to identify frames through which margins collapse. Fix O(N^2) propagation of float damage by maintaining a set of intervals damaged by floats (bug 61962) and be sure to damage the correct areas (bug 48138). Introduce nsCollapsingMargin to do correct collapsing of combinations of positive and negative margins (bug 50142). Clean up some odds and ends and fix another smaller O(N^2) problem in nsBlockFrame::AddFrames. r=attinasi, rbs sr=waterson	2001-10-25 01:08:40 +00:00
