* Issue #1355 - Make nsTableCellFrame::GetColIndex/GetRowIndex fasterwin7-72020-02-16-24/+17
| | | | We can devirtualize it, remove some branches.
* Issue #1355 - Do less work for columns not in the desired set in ↵win7-72020-02-06-12/+26
| | | | | | | | | | PaintRowGroupBackgroundByColIdx Do less work in PaintRowGroupBackgroundByColIdx for cells that are not in our desired set of columns. crash fix: Guard against empty column groups when building a display list for a table.
* Issue #1355 - Hit testing in large tables has become extremely slowwin7-72020-02-02-7/+30
| | | | Add dirty rect intersection checks so that we don't build unnecessary table part display items.
* Issue #1378 - Follow-up: make sure background items remain table-aligned.wolfbeast2020-02-02-1/+1

* Issue #146 - Part 2: Remove custom table painting component.wolfbeast2019-11-02-84/+0
| | | | | | Since we're now putting table borders and backgrounds properly in the display lists, we no longer need this custom component to do this work for us.
* Issue #146 - Part 1: Draw each table's background on their own displaywolfbeast2019-11-02-122/+146
| | | | | | | | | | | | | | list items. This patch does the following things: 1. Creates nsDisplayTableBorderCollapse that draws all collapse border of tables. 2. Stops the use of nsDisplayTableBorderBackground. 3. Lets column and column group frames generate display items. 4. When traversing the table, also traverses the column and column group frames. 5. For each type of table frame (col group, col, row group, row and cell), draws their own background.
* Issue #1230 - Part 1: Fix Back-computing percentages for intrinsic sizing in ↵Gaming4JC2019-09-28-4/+3
| | | | | | | | | | | | | | | | | | | | | | Layout CSS-Grid List of relevant patches applied: 1398537 part 2 - [css-multicol] Implement percentages for 'column-gap' (Gecko part). 1434478 part 1 - [css-grid] Stop back-computing percentage grid gaps when the percentage basis is indefinite. Treat them as zero sized instead. 1434478 part 2 - Stop back-computing percentage padding/margin when the percentage basis is indefinite. Treat them as zero sized instead. 1434478 part 3 - Remove IntrinsicISizeOffsetData::hPctPadding/hPctMargin members since they are now unused. 1434478 part 4 - Factor out constants like NS_UNCONSTRAINEDSIZE so they can be used in headers without needing nsIFrame.h (idempotent patch). 1434478 part 5 - Create nsLayoutUtils::ResolveToLength for resolving CSS <length-percentage> (idempotent patch). 1434478 part 6 - Propagate a percentage basis to nsIFrame::IntrinsicISizeOffsets for resolving padding/margin. This is needed only for CSS Grid since in other cases we're only using IntrinsicISizeOffsets in the inline-axis and the percentage basis is always indefinite for *intrinsic sizing*. When calculating the intrinsic size of grid items in the grid container's block axis however, we do have a definite size for the grid area in the inline-axis and it should be used per: https://drafts.csswg.org/css-grid/#algo-overview "2. Next, the track sizing algorithm resolves the sizes of the grid rows, using the grid column sizes calculated in the previous step." (Percentage padding/margin for grid items is always resolved against the grid area's inline-size nowadays.)
* Attach FrameProperties to each frame instead of using a shared hashtablewin7-72019-06-26-14/+17
| | | | Dispense the shared hashtable and instead attach the frame property list directly to nsIFrame.
* Use device pixels instead of CSS pixels for table borders.wolfbeast2018-10-07-38/+41
| | | | This resolves #821 (regression).
