title: Android WebView: weird rendering of 1px lines on hdpi screens
body: <p>I have a WebView that displays some generated HTML. The content includes a list and the list item CSS includes <code>border-top: 1px</code>.</p>
  
  <p>On hdpi devices the WebView tries to scale this line 1.5x. Sometimes the lines render as <em>1 real pixel</em> and sometimes they render as <em>2 real pixels</em>. In fact, it seems to pick 1 or 2 pixels alternately.</p>
  
  <p>I'm specifically looking for a solution that doesn't involve <code>&lt;meta name="viewport" content="target-densitydpi=device-dpi" /&gt;</code>. I <em>do</em> want the WebView to handle scaling as long as 1px lines are rendered consistently.</p>
