38 * @brief Creates several contact cards that animate between a folded and unfolded state.
40 * This demonstrates how different animations can start and stop at different times within the same Animation function.
41 * Additionally, this also shows how to morph between two different geometries.
43 * ContactCardLayouter: This class is used to lay out the different contact cards on the screen.
44 * This takes stage size into account but does not support relayouting.
45 * ContactCard: This class represents each contact card on the screen.
46 * Two animations are set up in this class which animate several properties with multiple start and stop times.
47 * An overview of the two animations can be found in contact-card.cpp.
48 * ContactCardLayoutInfo: This is a structure to store common layout information and is created by the ContactCardLayouter and used by each ContactCard.
49 * ContactData: This namespace contains a table which has the contact information we use to populate the contact cards.
50 * ClippedImage: This namespace provides a helper function which creates an ImageView which is added to a control that has clipping.
51 * This clipping comes in the form of a Circle or Quad.
52 * The Vertex shader mixes in the Circle and Quad geometry depending on the value of a uniform float.
53 * Animating this float between CIRCLE_GEOMETRY and QUAD_GEOMETRY is what enables the morphing between the two geometries.
