   <text style="font-size: 12">This prints 12 pixels high.</text>
   <text style="font-size: 12px">This prints 12 pixels high.</text>

   <!-- Now scale the coordinate system by 2. -->

      <!-- The following text will actually draw 24 pixels high
           because each unit in the new coordinate system equals
           2 units in the previous coordinate system. -->
      <text style="font-size: 12">This prints 24 pixels high.</text>

      <!-- The following text will actually still draw 12 pixels high
           because the CSS unit specifier has been provided. -->
      <text style="font-size: 12px">This prints 12 pixels high.</text>
