/**
* @class vtkAndroidRenderWindowInteractor
* @brief implements Win32 specific functions
* required by vtkRenderWindowInteractor.
*
*
* By default the interactor installs a MessageProc callback which
* intercepts windows' messages to the window and controls interactions by
* routing them to the InteractoStyle classes.
* MFC or BCB programs can prevent this and instead directly route any mouse/key
* messages into the event bindings by setting InstallMessageProc to false.
* This provides a minimal "Mapped" mode of interaction
*
