Chromium Compositor Picture Layer Deep Dive

This source provides an extensive, practitioner-focused examination of the Chromium Compositor's PictureLayerImpl class and its associated tiling stack, which manages the rasterization and drawing of complex layer content originating from Skia recordings. The document systematically walks through the class's responsibilities, detailing how it handles tiling management, decides the raster scale and translation for content fidelity (including special rules for LCD text), and participates in the overall rendering pipeline by emitting draw quads. A major focus is placed on the difference between ideal scales (geometric target) and raster scales (policy choice driven by stability heuristics like pinch/animation) and the critical invariants, such as ensuring only one high-resolution tiling exists at the chosen raster scale. The text also includes practical tips for modifying the code, emphasizing stability and adherence to complex constraints like hardware-mandated maximum contents scale caps for masks.
