Optimize the way AnimatedImage display its content
Since QtQuick2, the AnimatedImage component is less efficient than it
was with QtQuick1, using more CPU and RAM.
This commit makes it upload when required each animation frame as a
cached texture (using QQuickPixmapCache) to speed up the component.
