title: Antialias the view being transformed
body: <p>I am transforming child views in my viewgroup when I'm swiping through the viewgroup (kind of a cover-flow effect). I am using <code>matrix.setPolyToPoly</code> for transformation. The views have borders which need antialiasing severely.</p>
  
  <p>So far I've tried to use</p>
  
  <pre><code>canvas.setDrawFilter(new PaintFlagsDrawFilter(0, Paint.ANTI_ALIAS_FLAG));
  </code></pre>
  
  <p>in my children's <code>onDraw</code>, but it doesn't seem to change anything. Also, I'm aware of <code>BitmapDrawable.setAntiAlias(true)</code>, but my children are not drawables, but full-blown viewgroups with views inside, so I cannot use that.</p>
