If true, the textobject in a mediaobject is preferred over any imageobject.

(Of course, for output formats other than Texinfo, you usually want to prefer the imageobject, but Info is a text-only format.)

In addition to the values true and false, this parameter may be set to 2 to indicate that both the text and the images should be output. You may want to do this because some Texinfo viewers can read images. Note that the Texinfo @image command has its own mechanism for switching between text and image output — but we do not use this here.

The default is true.
