// Description:
// Tests semi-transparent window owning control with background display properly when having a child window
// owning semi-transparent control.
// Creats a window application with two semi-transparent window owning parent controls both with background. 
// A semi-transparent child window owning control is created for each parent control. One of the child control
// enables transparent property properly, the other does not. 
// The child control which enables transparent property properly should not cause the background of parent control
// to redraw thus in all circumstance its parent control background drawing count should be less than the one doesn't
// enable transparent control with provided function.
//
