PlatformCanvas2DContext

Defined in: platform/types.ts:266

The offscreen 2D context the engine uses: image decode (drawImage/ getImageData/clearRect) and dynamic glyph rasterization (font/measureText/ fillText/…). Every member is present on BOTH CanvasRenderingContext2D and OffscreenCanvasRenderingContext2D with covariance-compatible types, so both are assignable here.
