title: Sublime text 2 : highlight/color a line by plugin
body: <p>I'm trying to create a plugin where i need do <em>colorize/highlight</em> a full line (not text).</p>
  
  <p>For example if i do something like:</p>
  
  <pre><code> for region in self.view.sel():
          if region.empty():
              line = self.view.line(region)
              self.view.add_regions('put-some-bg-color', [line], 'keyword', 'bookmark', sublime.DRAW_OUTLINED)
  </code></pre>
  
  <p>this will only put a <em>outline</em> on text until the newline char (\n). </p>
  
  <p>I would like to put a backgroud color one the whole line, like it's done by the "<strong>highlight_line</strong>" preference.</p>
