On Windows GetSystemMetrics does return the size the (virtual) desktop
has, but it does not subtract the space occupied by the Windows
TaskBar (see: http://msdn.microsoft.com/en-us/library/ms724385(v=vs.85).aspx).
You have to use SystemparametersInfo(SPI_GETWORKAREA, 0, @WorkArea, 0
); with WorkArea being of type TRect;
