/*!
\brief The class representing a Toonz palette object.
\par Rationale
A palette is a collection of <I>color styles</I> that adds a level of indirection
on color selections when drawing certain graphical objects.
\n
Palette-based objects store <I>style identifiers</I> into an associated palette object,
rather than the colors directly. When a color needs to be accessed, the palette
objects is queried for a <I>style id</I>, and the associated \a style is returned.
\n
A TColorStyle instance generalizes the notion of \a color, providing the ability to
reduce a style instance to a color, \a and specialized drawing functions for
<I>vector graphics</I> objects.
\par Reserved colors
A palette object has two fixed \a reserved styles - which <I>cannot be removed</I> - at
indexes \p 0 and \p1. Index \p 0 is reserved for the \b transparent color. Index \p 1
is reserved for the \b ink color, initialized by default to black.
\par Syntax
A palette is supposedly created <B>on the heap</B>, to the point that, <I>in current
implementation</I>, copy and assignment are \a forbidden. This behavior is somewhat
inconsitent since a palette \b is currently \a clonable and \a assignable with the
appropriate functions. Normalization to common C++ syntax should be enforced ASAP.
\sa The TColorStyle class.
