title: Progress bar does not fit the background drawable
body: <p>I'm working on a horizontal progress bar and the progress does not seem to be fitting the drawable image. It starts after like 5dp.</p>
  <p>This is my code.</p>
  <pre><code>&lt;SeekBar
      style=&quot;?android:attr/progressBarStyleHorizontal&quot;
      android:id=&quot;@+id/progress_bar&quot;
      android:layout_width=&quot;1070dp&quot;
      android:layout_height=&quot;match_parent&quot;
      android:layout_marginLeft=&quot;20dp&quot;
      android:layout_gravity=&quot;center_vertical&quot;
      android:layout_weight=&quot;0.33&quot;
      android:background=&quot;@drawable/progress_bar&quot;
      android:max=&quot;100&quot;
      android:progressDrawable=&quot;@drawable/seekbar_style&quot; /&gt;
  </code></pre>
  <p>My seekbar style.</p>
  <pre><code>&lt;layer-list xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;&gt;
  &lt;item android:id=&quot;@android:id/progress&quot;&gt;
      &lt;clip&gt;
          &lt;shape&gt;
              &lt;corners android:radius=&quot;4dip&quot; /&gt;
              &lt;gradient
                  android:angle=&quot;270&quot;
                  android:endColor=&quot;#ff0a75b0&quot;
                  android:startColor=&quot;#ff0a75b0&quot; /&gt;
          &lt;/shape&gt;
      &lt;/clip&gt;
  &lt;/item&gt;
  &lt;item android:id=&quot;@android:id/secondaryProgress&quot;&gt;
      &lt;clip&gt;
          &lt;shape&gt;
              &lt;corners android:radius=&quot;4dip&quot; /&gt;
              &lt;gradient
                  android:angle=&quot;270&quot;
                  android:endColor=&quot;#ff0a75b0&quot;
                  android:startColor=&quot;#ff0a75b0&quot; /&gt;
          &lt;/shape&gt;
      &lt;/clip&gt;
  &lt;/item&gt;
  </code></pre>
    
  <p>What am I doing wrong?</p>
