Aspect Ratio handling simplified by using floating point integers:
- Multiplication of value (or inverse value) to a known side for Scaling
- No unequal equal values such as "4/3" vs "8/6" vs "20/15"
- Truly "Empty" aspect ratios, even if one dimension is not 0
Before issue #146, border-radius on row groups, rows, column groups, or columns don't apply to the background of each cell, yet the border-radius on the cell itself does.
After issue #146, the behaviors changed. In this patch, I tried to revert the behaviors of border-radius on table row groups, rows, column groups, or columns back to what happened before issue #146.
Also: Don't override GetBorderRadii in nsBCTableCellFrame.
Part 1: Remove current table item, as it's never set.
Part 2: Get rid of generic table painting code, and handle each class separately.
Part 4: Hoist outline skipping into col(group) frame code.
Part 5: Skip box-shadow for table column and column groups.
Part 6: Store column and column group backgrounds separately, and then append them before the rest of the table contents.
Part 7: Pass rects in display list coordinates to AppendBackgroundItemsToTop.
Part 8: Create column and column group background display items as part of the cell's BuildDisplayList.
Part 9: Used cached values instead of calling nsDisplayListBuilder::ToReferenceFrame when possible, since it can be expensive when the requested frame isn't the builder's current frame.
Part 10: Make sure we build display items for table parts where only the normal position is visible, since we may need to create background items for ancestors at that position.
Part 11: Create an AutoBuildingDisplayList when we create background items for table columns and column groups, so that we initialize the invalidation state correctly.
Bug 1441796 - Part 1: Optimize the (pseudo)-stacking context conditions
Bug 1441796 - Part 3: Reuse the results in nsIFrame::BuildDisplayListForStackingContext() for ChildrenHavePerspective(), IsTransformed(), and Combines3DTransformWithAncestors()
Bug 1512244 - Part 1: Cleanup DescendIntoChild
* Fixup FindFrameForContentSibling to don't duplicate work and trigger assertions for display: contents
* Enable lazy frame construction for display: contents direct descendants
Tag #1375
* Cleanup a bit the ShadowRoot code
* Privatize ShadowRoot methods
* When the shadow tree distribution changes, post a restyle + reframe
* Simplify ShadowRoot::IsPooledNode
* Be a bit better at detecting distribution changes
Tag #1375
* Use inFlowFrame to check the target frame is summary and its parent is details
* Check summary frame instead of summary element on removing the summary
Tag #1375
* Add a node property to access the ::before and ::after pseudo-elements
* Look for the frame for ::before and ::after pseudos
* Clean up pseudo-element props
* Simplify nsLayoutUtils callers, and make child iterators notice display: contents pseudos
Tag #1375
* Tidy RestyleManager::ContentStateChanged
* Convert UndisplayedMap to a typed hashtable
* Cleanup infallible or unchecked nsCSSFrameConstructor methods
Tag #1375
* Prevent canvas custom content from becoming NAC when reframing the root element
* Add an API to get computed style values through an AnonymousContent object
Tag #1375
* Stop using a node bit for HasExplicitBaseURI
* Move MAY_HAVE_CLASS to mBoolFlags
* Add a flag to indicate that a node is native anonymous content
* Allow tagging of pseudo-implementing native anonymous content with the pseudo type at creation time, and eliminate explicit style contexts in nsIAnonymousContentCreator::ContentInfo
Tag #1375
Since we are using vsync for timing anyway in the layout refresh driver,
there is no need to bump the system timer resolution down to 1 ms.
This resolves#1507.
This changes the work we do for document.open() in the following ways:
- We no longer create a new Window when doing document.open().
We use the same Window but remove all the event listeners on the
existing DOM tree and Window before removing the document's existing
children to provide a clean slate document to use for .write().
- We no longer create a session history entry (previously would be a
wyciwyg URI). We now replace the current one, effectively losing the
entry for the original document.
- We now support document.open() on windowless documents.
list collisions when processing the background color of a table.
This is effectively #146 Part 3c to go along with the other 2 there.
This resolves#1308.
