Andreas Kling f0abf5a43b LibWeb: Avoid allocating DOMRect objects for internal engine use ... Instead of bothering the GC heap with a bunch of DOMRect allocations, we can just pass around CSSPixelRect internally in many cases. Before this change, we were generating so much DOMRect garbage that we had to do a garbage collection *every frame* on the Immich demo. This was due to the large number of intersection observers checked. We still need to relax way more when idle, but for comparison, before this change, when doing nothing for 10 seconds on Immich, we'd spend 2.5 seconds updating intersection observers. After this change, we now spend 600 ms.		2025-03-22 14:33:59 -05:00
