/**
* Builds and starts animations. When possible, Honeycomb+ animations
* (i.e., Property Animators) are used, even on pre-Honeycomb, which is
* possible because we use the NineOldAndroids compatibility library.
* The only time Property Animators are not used -- i.e., the only time
* we revert to using old-style view animations -- is when the animation's
* transform property is set to a Ti2DMatrix that is "complicated", where
* complicated means one of the following is true:
* <ol>
* <li>The Ti2DMatrix is the product of matrix multiplication, e.g.,
* <pre>
* {@code
* var newMatrix = baseMatrix.multiply(otherMatrix);
* }
* </pre>
* </li>
* <li>The Ti2DMatrix is the inverse of another matrix, e.g.,
* <pre>
* {@code
* var newMatrix = oldMatrix.invert();
* }
* </pre>
* </li>
* <li>The Ti2DMatrix is the result of concatenating an operation more
* than once, e.g.,
* <pre>
* {@code
* var newMatrix = baseMatrix.rotate(45).rotate(10);
* }
* </pre>
* or
* <pre>
* {@code
* var newMatrix = baseMatrix.rotate(45).scale(2,2).rotate(10)
* }
* </pre>
* which contains two rotates.
* </li>
* </ul>
* Concatenation of matrix operations does not in itself cause old style
* animations to run -- only if an operation is repeated. For example...
* <pre>
* {@code
* var newMatrix = baseMatrix.rotate(45).translate(10,10).scale(2,2)
* }
* </pre>
* ...would be fine since no operation is duplicated. In such a case, a set of
* Honeycomb+ property Animators can be safely derived.
