There is a bug where if converting from a polygon in the form
<polygon points="0 0 0 100 100 100 100 0 0 0" fill="#0000FF"/>
results in an invalid vector path of the form
<path android:fillColor="#0000FF" android:pathData="M0 L0 L0 L100 L100 L100 L100 L0 L0 L0 z" />
where it should be
<path android:fillColor="#0000FF" android:pathData="M0,0 L0,100 L100,100 L100,0 L0,0 z" />
