Control.Invoke allows a method to be invoked on the same thread as the one
the control was created on. Unlike in the full .NET Framework, the .NET
Compact Framework does not support the Control.Invoke overload for passing an
array of objects to pass as arguments. This ControlInvoker class overcomes
this limitation.
