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

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

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.
