wxHTML can be used as a generic rich text viewer - for example to display
a nice About Box (like those of GNOME apps) or to display the result of
database searching. There is a wxFileSystem class which allows you to use

extend wxHtml library with new, unsupported tags. Not only that,
you can even use your own application-specific tags!

Because wxHtmlWindow is derived from wxScrolledWindow and not from
wxFrame, it doesn't have visible frame. But the user usually wants to see
the title of HTML page displayed somewhere and the frame's titlebar is
the ideal place for it.

Page title "Hello, world!" will be displayed as "HTML : Hello, world!"
