Blink Core Paint Rendering Architecture

This documentation details the Blink rendering engine's process for converting a LayoutObject tree into a format the compositor can process. The operation is split into two primary phases: PrePaint, which handles paint invalidation and property tree construction, and Paint, which generates a list of display items. Key concepts include stacking contexts, which manage the z-ordering of elements, and paint property trees that handle visual transformations and effects. The system optimizes performance through result caching and isolation boundaries that prevent unnecessary re-processing of subtrees. Additionally, the engine manages specialized tasks like scrollbar painting, hit-test recording, and the alignment of drawings to screen pixels to avoid blurriness. Together, these components ensure that web content is translated into efficient cc::Layers for final display.
