I just thought of one other thing:  You can also use Javascript in the  
web view to do the highlighting, rather than paint an overlay.  Just  
set the style of the <span> you care about to a simple background  
highlighting using inline CSS.

The webview comes with all this Javascript power built in, so it's  
good to use it rather than try to write C++ code that can't really be  
as precise as the JS, because unlike the JS, it has no DOM API to  
access.

Unless you want the C++ API, which is still in development and thus  
maybe can be gotten from gitorious??  Not sure; check the article  
below.  (Scheduled for 4.6 release.)
