 Abstract: A view that implements NSTextInputClient by using the Cocoa text system objects NSTextStorage, NSLayoutManager, and NSTextContainer. The view centers and displays any typed text. When the user enters a newline, the text fades out, leaving an empty field. The view also handles marked text, such as the acute accent that appears when typing the character "é" (option-e, then e). Marked characters are displayed in gray.

  Version: 1.2
