/*
 * transform: A light jQuery cssHooks for 2d transform
 *
 * limitations:
 * - requires jQuery 1.4.3+
 * - Should you use the *translate* property, then your elements need to be absolutely positionned in a relatively positionned wrapper **or it will fail in IE678**.
 * - incompatible with "matrix(...)" transforms
 * - transformOrigin is not accessible
 *
 * latest version and complete README available on Github:
 * https://github.com/louisremi/jquery.transform.js
