Message:

Add a way to collect scrolling performance data (viewport tile coverage) with UI-side compositing
​https://bugs.webkit.org/show_bug.cgi?id=140474

Reviewed by Tim Horton.
Source/WebCore:

Add accessors for standard names for container CALayer for each of the tile grids,
and when tile grids are swapped, update those names as appropriate.

  • WebCore.exp.in:
  • platform/graphics/ca/TileController.cpp:

(WebCore::TileController::tileGridContainerLayerName):
(WebCore::TileController::zoomedOutTileGridContainerLayerName):
(WebCore::TileController::setContentsScale):

  • platform/graphics/ca/TileController.h:
  • platform/graphics/ca/TileGrid.cpp:

(WebCore::TileGrid::TileGrid):
(WebCore::TileGrid::setIsZoomedOutTileGrid):

  • platform/graphics/ca/TileGrid.h:

Source/WebKit2:

Add a private method to enable scrolling data collection to WKWebView. When enabled, create
a RemoteLayerTreeScrollingPerformanceData object that collects "blank pixel" data on
every layer tree commit and scroll, and stores them in a vector. A second SPI call
allows retrieval of an NSArray of this data.

To allow RemoteLayerTreeScrollingPerformanceData to find the correct layer which
contains the main tile grid, we set a layer name on the appropriate layer (even
in release builds).

  • UIProcess/API/Cocoa/WKWebView.mm:
