Test inheritance of animated properties.

Three colored text strings appear. All three are inside of the same 'g' element. The 'g' element has its 'font-size' animated from 30 to 40, its 'stroke-width' animated from .5 to 2, and its 'fill-opacity' from 1 to .2.

The first colored 'text' element shows a sample text string which reflects how a text string will be rendered at the very start of the animation. The second colored 'text' element shows a sample text string which reflects how a text string will be rendered at the end of the animation. The third colored 'text' element animates because the 'font-size', 'stroke-width' and 'fill-opacity' properties are animated on its parent 'g' element, and unlike the previous two 'text' elements, these properties are not specified on the 'text' element itself.
