+
+ Reviewed by Simon Fraser.
+
+ Make sure backdrop layers don't tile. If they are big
+ enough, we'll leave it to the platform compositor to handle.
+
+ This also fixes a bug where if a layer changed from a backdrop
+ type to a tiled type, it would still retain its custom appearance
+ and we'd try to add children to the wrong layer.
+
+ Test: compositing/media-controls-bar-appearance-big.html
+
+ * platform/graphics/ca/GraphicsLayerCA.cpp:
+ (WebCore::GraphicsLayerCA::commitLayerChangesBeforeSublayers): Check if
+ a layer needs a backdrop before checking if it needs to tile.
