Andreas Kling	7f9f916470	LibWeb: Make tiled backgrounds scroll with content ... Previously the page background was always draw relative to the viewport instead of following with the content. This should eventually become an opt-in mode (via CSS "background-attachment") but for now let's have the default behavior be that backgrounds scroll with content. Also take this opportunity to move the background painting code from the two web views to a shared location in InitialContainingBlockBox.	2021-03-07 13:49:20 +01:00
Andreas Kling	9b0ca75f84	LibWeb: Add Frame::ViewportClient and use it for Layout::ImageBox ... Image boxes want to know whether they are inside the visible viewport. This is used to pause/resume animations, and to update the purgeable memory volatility state. Previously we would traverse the entire layout tree on every resize, calling a helper on each ImageBox. Make those boxes register with the frame they are interested in instead, saving us all that traversal. This also makes it easier for other parts of the code to learn about viewport changes in the future. :^)	2021-01-30 12:29:11 +01:00
