/*! \class Previewer
The Previewer class is a singleton which deals with Preview renders of isolated
frames.
The main purpose of this class, as of Toonz 6.x, is that of managing preview
requests coming
from Toonz's Scene Viewers; however, it is designed to support requests from a
generic
\b Previewer::Listener class.
The Previewer is a singleton, meaning that it centralizes requests from many
possible listeners
in a single collection of previewed frames.
\n \n
The most important method of the class is \b getRaster(), which attempts
retrieval of a certain
frame and, if the frame was not calculated yet, makes the Previewer build it.
\n
The update() slot is provided to refresh the cached information about the
entire collection
of currently stored frames. Updated frames are recalculated only upon a new
getRaster(), in case the previously
stored information no more match the current frame description.
\n
The clear() methods make the Previewer erase all stored information about one
or all frames,
so that the following getRaster() will forcibly recalculate the requested frame.
