// .NAME vtkCornerAnnotation - text annotation in four corners
// .SECTION Description
// This is an annotation object that manages four text actors / mappers
// to provide annotation in the four corners of a viewport
//
// .SECTION Special input text:
// - <image> : will be replaced with slice number (relative number)
// - <slice> : will be replaced with slice number (relative number)
// - <image_and_max> : will be replaced with slice number and slice max (relative)
// - <slice_and_max> : will be replaced with slice number and slice max (relative)
// - <slice_pos> : will be replaced by the position of the current slice
// - <window> : will be replaced with window value
// - <level> : will be replaced with level value
// - <window_level> : will be replaced with window and level value
