An [Array] of devices which should always use the ANGLE renderer.

Maximum number of canvas items commands that can be drawn in a single viewport update. If more render commands are issued they will be ignored. Decreasing this limit may improve performance on bandwidth limited devices. Increase this limit if you find that not all objects are being drawn in a frame.
