WebGLRenderer accepts WebGLRenderingContext instances with backwards compatibility fallback and allows coordinateSystem reconfiguration.

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

WebGLRenderer throws an explicit error when initialized with a WebGLRenderingContext (WebGL 1), requires WebGL 2, and exposes a read-only coordinateSystem returning WebGLCoordinateSystem (2000).
outputColorSpace defaults to SRGBColorSpace ('srgb') and setting it synchronizes drawingBufferColorSpace and unpackColorSpace on the underlying WebGL context.
reversedDepthBuffer requires the EXT_clip_control extension to activate, invoking clipControlEXT and otherwise falling back to false on capabilities.
getClearAlpha() defaults to 0 when alpha is enabled in renderer parameters or WebGL context attributes, and defaults to 1 when alpha is disabled.
setPixelRatio scales canvas physical dimensions and getDrawingBufferSize by the ratio while getSize reports logical dimensions and setSize updates style properties.
