title: Android Support Library 23.2 vector drawables are blurry
body: <p>The latest version of the Android Support Library (23.2) adds support for vector drawables. It appears to do this by rasterizing the vectors on the fly on platforms that don't natively support vector drawables.</p>
  
  <p>However, the rasterize image seems to be a fixed size rather that dependent on usage. Here's an example.</p>
  
  <p><strong>Vector</strong></p>
  
  <pre><code>&lt;vector xmlns:android="http://schemas.android.com/apk/res/android"
          android:width="24dp"
          android:height="24dp"
          android:viewportWidth="24.0"
          android:viewportHeight="24.0"&gt;
      &lt;path
          android:fillColor="#FF000000"
          android:pathData="M12,2C6.48,2 2,6.48 2,12s4.48,10 10,10 10,-4.48 10,-10S17.52,2 12,2zm0,3c1.66,0 3,1.34 3,3s-1.34,3 -3,3 -3,-1.34 -3,-3 1.34,-3 3,-3zm0,14.2c-2.5,0 -4.71,-1.28 -6,-3.22 0.03,-1.99 4,-3.08 6,-3.08 1.99,0 5.97,1.09 6,3.08 -1.29,1.94 -3.5,3.22 -6,3.22z"/&gt;
  &lt;/vector&gt;
  </code></pre>
  
  <p><strong>Layout</strong></p>
  
  <pre><code>&lt;ImageView
    android:layout_width="128dp"
    android:layout_height="128dp"
    android:id="@+id/imageView"
    app:srcCompat="@drawable/vector1"/&gt;
  </code></pre>
  
  <p>The vector is 24dp x 24dp. It's used in an ImageView that's 128dp x 128dp. On platforms that's don't support vector drawables, the resulting image is blurry because the vector is rasterized at 16dp and resized to 128dp.</p>
  
  <p>The only solution I've found is to create a separate vector drawable for each intended size. It's pretty annoying to create a bunch of duplicate vectors with only the height and width changes. And that doesn't solve the problem if you want the drawable to fill_parent or be dynamically sized in some other way.</p>
  
  <p>Having to define the dimensions of your vector images in advanced <em>almost</em> completely defeats the benefit of using vectors in the first place.</p>
  
  <p>Does anyone have a true work around?</p>
