Querying AbsoluteSize / AbsolutePosition on a Gui element that is within a layout is EXTREMELY costly. It seems to recompute the layout every time you request these values. We primarily use this for culling of Gui elements. It would be extremely useful to A: know whether or not a Gui element is actually visible on the screen. B: Not have querying these values be so expensive by using a cached size for that frame. We have tried creating our own caching systems but it does not work properly (it requires a LOT of edge cases). It should only update these values when a child element has been resized or the screen size itself effected the layout - not just EVERY time you query these values.
Expected behavior
Querying AbsoluteSize / AbsolutePosition should be instant and not recompute the entire UI needlessly.
Additionally, we should have a VERY fast way to detect if a Gui element is visible on the screen.
