- OverflowChangedTracker::AddFrame now accepts an enumerated type parameter to
indicate if the overflow areas of children have changed (CHILDREN_CHANGED),
the overflow areas of the children have changed and the parent have changed
(CHILDREN_AND_PARENT_CHANGED), or if only the transform has changed
(TRANSFORM_CHANGED).
- OverflowChangedTracker::Flush no longer falls back to calling
nsIFrame::UpdateOverflow when a frame lacks a PreTransformOverflowAreas
property.
- Added an additional change hint, nsChangeHint_ChildrenOnlyTransform, which
results in TRANSFORM_CHANGED being passed in to
OverflowChangedTracker::AddFrame.
- In nsIFrame::FinishAndStoreOverflow, the passed in overflow is now stored as
the InitialTransformProperty for elements that are IsTransformed().
- Partially corrected Bug 926155, by only calling
OverflowChangedTracker::AddFrame on parents of the sticky element during
StickyScrollContainer::UpdatePositions, using CHILDREN_CHANGED.

Ideally we'd make this property inaccessible to Web content style sheets, but
that seems hard since view-source and plain text documents seem to load in a
context that's very similar to Web content as far as the style system is
concerned. It doesn't matter much since it's quite safe and unlikely to be
discovered or used by anyone.

This adds a new eCSSUnit_SharedList type for nsCSSValue, which is a
reference counted object that contains an nsCSSValueList. We need this
so that nsStyleDisplay::mSpecifiedTransform can hold a strong reference
to a specified transform list value. When 'transform' is specified
using a variable reference, the resulting nsCSSValue does not stick
around in the Declaration object, so we wouldn't be guaranteed that
it lives long enough for nsStyleDisplay to keep referencing it.
This defines a class CSSVariableValues which is used to store
computed variable values. We store them a bit differently from
CSSVariableDeclarations -- here we have a hash table of variable names
to integer IDs, and then an array of variables where the array index
is the ID. This is because later on we'll want a stable order for the
variables to return from DOM APIs.
In addition to the string value of the variable, we store the type
of the first and last token of the variable value. This information
will be used when resolving entire variable reference containing
values, to determine when to insert "/**/" before and after a resolved
var(blah) token.
We add a CSSVariableValues member to nsStyleVariables.
This adds an nsStyleVariables on which computed variable values
will be stored. We don't actually have any properties assigned to
nsStyleVariables; eCSSPropertyExtra_Variables which we added earlier
isn't a real property. To avoid compiler errors for gVariableFlags
being a zero length array, we stick a dummy entry in there.
nsRuleNode::ComputeVariablesData does nothing for the moment.
nsStyleVariable nsChangeHint calculations always return 0, as later
we will compare the actual properties that reference variables to
see what changes are required for them.
There's no reason to use inheritance here, and using plain typedefs avoids massive
amounts of code duplication for the common case of copying with mem*. Code savings
on Android come in at about 570K (!), or ~2% of libxul .text size, which is a massive
win.
