+    The purpose of this class is to display rich content pages (either local file or
+    downloaded via HTTP protocol) in a window based on a subset of the HTML standard.
     The width of the window is constant - given in the constructor - and virtual height
     is changed dynamically depending on page size.
     Once the window is created you can set its content by calling SetPage() with raw HTML,
     LoadPage() with a wxFileSystem location or LoadFile() with a filename.

     wxHtmlWindow uses the wxImage class for displaying images, as such you need to
     initialize the handlers for any image formats you use before loading a page.
