    Set of default supported desired capabilities.
    Use this as a starting point for creating a desired capabilities object for
    requesting remote webdrivers for connecting to selenium server or selenium grid.
    Usage Example::
        from selenium import webdriver
        selenium_grid_url = "http://198.0.0.1:4444/wd/hub"
        # Create a desired capabilities object as a starting point.

    Note: Always use '.copy()' on the DesiredCapabilities object to avoid the side
    effects of altering the Global class instance.
