Andreas Kling	15dc48b431	LibWeb: Make PaintableBox::enclosing_stacking_context() cheaper ... No need to call the expensive establishes_stacking_context() here, as we've already built the stacking context tree and can simply test for the presence of existing stacking contexts.	2022-03-18 15:18:48 +01:00
Andreas Kling	be5f0b5ac4	LibWeb: Move text fragment painting to PaintableWithLines ... All the other painting code has moved to paintables already.	2022-03-16 23:13:05 +01:00
Andreas Kling	b14c6eaef3	LibWeb: Let paintables cache their containing block and absolute rect ... The absolute rect of a paintable is somewhat expensive to compute. This is because all coordinates are relative to the nearest containing block, so we have to traverse the containing block chain and apply each offset to get the final rect. Paintables will never move between containing blocks, nor will their absolute rect change. If anything changes, we'll simpl make a new paintable and replace the old one. Take advantage of this by caching the containing block and absolute rect after first access.	2022-03-12 00:39:31 +01:00
