/*
* An overview of what goes on here:
*
* We want to provide the user with a loading animation of a unified search result list item "skeleton".
* This skeleton has a square and two rectangles that are meant to represent the icon and the text of a
* real search result.
*
* We also want to provide a nice animation that has a dark gradient moving over these shapes. To do so,
* we very simply create rectangles that have a gradient going transparent->dark->dark->transparent, and
* overlay them over the shapes beneath.
*
* We then use NumberAnimations to move these gradients left-to-right over the base shapes below. Since
* the gradient rectangles are child elements of the base-color rectangles which they move over, as long
* as we ensure that the parent rectangle has the "clip" property enabled this will look nice and won't
* spill over onto other elements.
*
* We also want to make sure that, even though these gradient rectangles are separate, it looks as it is
* one single gradient sweeping over the base color components
