WebGL Only. Whether to enable anti-aliasing. This may affect performance.
WebGL Only. User-provided WebGL rendering context object.
WebGL Only. A hint indicating what configuration of GPU is suitable for the WebGL context,
can be 'default', 'high-performance' or 'low-power'.
Setting to 'high-performance' will prioritize rendering performance over power consumption,
while setting to 'low-power' will prioritize power saving over rendering performance.
WebGL Only. Whether the compositor will assume the drawing buffer contains colors with premultiplied alpha.
WebGL Only. Whether to enable drawing buffer preservation. If enabled, the drawing buffer will preserve
its value until cleared or overwritten. Enable this if you need to call toDataUrl on the WebGL context.
OptionaluseDeprecated since 7.0.0, use premultipliedAlpha and backgroundAlpha instead.
Pass-through value for canvas' context attribute alpha. This option is for cases where the
canvas needs to be opaque, possibly for performance reasons on some older devices.
If you want to set transparency, please use backgroundAlpha.
WebGL Only: When set to 'notMultiplied', the canvas' context attribute alpha will be
set to true and premultipliedAlpha will be to false.
Options for the context system.
