Robert O'Callahan 7c34e38876 Bug 733607. Restructure logic to compute snapped bounds of display items in layer coordinates. Moves responsibility for computing snapped bounds from within the display items to callers of GetBounds/GetOpaqueRegion. r=tnikkel 
Previously we snapped the results of nsDisplayItem::GetBounds and
nsDisplayItem::GetOpaqueRegion internally. By tracking which display items were
inside transforms, we disabled snapping quite conservatively whenever an ancestor
had a transform, which is undesirable.

With this patch, we don't snap inside GetBounds or GetOpaqueRegion, but just return
a boolean flag indicating whether the item will draw with snapping or not. This flag
is conservative so that "true" means we will snap (if the graphics context has a transform
that allows snapping), but "false" means we might or might not snap (so it's always safe
to return false).

FrameLayerBuilder takes over responsibility for snapping item bounds. When it converts
display item bounds to layer pixel coordinates, it checks the snap flag returned from
the display item and checks whether the transform when we draw into the layer will be
a known scale (the ContainerParameters scale factors) plus integer translation. If both
are true, we snap the item bounds when converting to layer pixel coordinates. With
this approach, we can snap item bounds even when the items have ancestors with active
transforms.

nsBidiPresUtils.h Add a mParagraphDepth member to BidiParagraphData and cache it on frames to track nested bidi-isolated paragraphs. Use mParagraphDepth (* 2 + isRTL in order to keep LTR even and RTL odd) as the initial paragraph embedding level instead of pushing a stack of embedding codes. Pass the <bdi> frame instead of its first-child to BidiParagraphData::Reset and save a call to GetParent(). Split inline ancestors before and after bidi-isolated paragraphs, in the same way that we currently do between runs in different directions. This required also adding code to SplitInlineAncestors to handle situations where the parent frame is being split before its first child or after its last child. In JoinInlineAncestors, prevent frames that belong to paragraphs isolated from one another from being rejoined. Bug 712600, r=ehsan, roc 2012-01-11 21:26:02 +02:00
