Loads HTML from a raw resource, i.e., a HTML file in res/raw/.
This allows translatable resource (e.g., res/raw-de/ for german).
The containing HTML is parsed to Android's Spannable format and then displayed.

@param resId       for example: R.raw.help
@param imageGetter for fetching images. Possible ImageGetter provided by this library:
                   HtmlLocalImageGetter and HtmlRemoteImageGetter
