请问DirectShow sample中的TextOut
// Demonstration instructions
//
// Start GraphEdit, which is available in the SDK DXUtils folder.
// Drag and drop the CLOCKTXT.AVI movie into the tool and it will be rendered.
// Notice that the AVI splitter filter will display three output pins:
// - A video output pin
// - An audio waveform output pin
// - A text output pin ("Lyrics)
//
// GraphEdit may automatically render the "Lyrics" pin to another filter,
// such as the "Internal Script Command Renderer". If so, just select the
// filter that connects the Lyrics pin and press the delete key to remove
// the connection. Next, choose Graph->Insert Filters, expand the
// DirectShow Filters node, select Text Display, and close the dialog box.
// Connect the Lyrics pin to the input of this Text Display filter using
// the mouse or by right-clicking on the Lyrics pin and selecting Render.
//
//
// Click on Pause and then Run on the GraphEdit frame and you will see the video
// in one window on the desktop and another video with text being drawn into it.
// The words being displayed are "One", "Two". "Three", etc., and the point at
// which they are displayed should match with the images in the other window.
我怎么找不到在上面这段文字中所述的Text Display？这个是什么？
