a8a9a3744c Bug 624699. Fix some landscape printing bugs. r=roc

Robert O'Callahan
c2f7a1e950 Bug 513082. Instead of passing aDirtyRect to nsDisplayItem::Paint, have nsDisplayList::OptimizeVisibility (renamed to ComputeVisibility) compute the intersection of the visible region with the bounds of each display item and store the result in the item's mVisibleRect. This lets us do less work to paint display items which have a small intersection with the visible region but a large intersection with the bounding-box of the visible region. r=dbaron

3498a5f86e Bug 396185 - Make nsIFrame derivatives and helper abstract classes use a different dynamic-cast system than nsISupports:
* we know all types frames may be cast to at compile time, so instead of extensible GUID IIDs, use a big enum (see nsQueryFrame::FrameIID)
* eliminate all vestiges of refcounting, since frames aren't refcounted

Some frames (SVG frames in particular) still implement nsISupports-derived interfaces, for example nsISVGValue. There is a FrameIID for nsISVGValue that lets you go from a frame to the XPCOM interface, but you can't query back.

r+sr=roc

nsITextControlFrame didn't have an IID the first time around, but this wasn't a compile error because nsITextControlFrame::kFrameIID inherited from nsIFormControlFrame::kFrameIID. I've added a static analysis pass to verify the correct behavior, since I can't figure out a way to make the compiler do it.

This patch locally causes two REFTEST-UNEXPECTED-PASS for Bidi stuff. It's possible that I accidentally fixed a bug, but I'm not sure, so I'm going to wait for the tinderboxes to confirm my local results.

4f69ec2c2e Guarantee that the pres context's device context will be non-null by returning failure from Init() if it's null. Rename inline getter GetDeviceContext() to DeviceContext(), convert all callers to use the inline getter, and remove the virtual/refcounting getter.

e65d2d2fe5 Eliminate nsIStyleSet as an XPCOM interface, making the implementation internal to layout. Frame constructor ownership moves to the pres shell, and the style set methods that forward to the frame constructor are gone. Rewrote style set sheet add/remove to reduce code size.

dfe3513814 Change all callers of nsIPresContext::GetShell() to use the non-refcounting versions. Most callers now use PresShell(), a few that were checking for null conditions are using GetPresShell() -- this will be remedied once we can ensure that a prescontext never has a null pres shell.
