/*!

  \brief    The class representing a Toonz palette object.

  \par Rationale

    A palette is a collection of color styles that adds a level of indirection

    on color selections when drawing certain graphical objects.

\n

    Palette-based objects store style identifiers into an associated palette object,

    rather than the colors directly. When a color needs to be accessed, the palette

    objects is queried for a style id, 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

    vector graphics objects.

  \par Reserved colors

    A palette object has two fixed \a reserved styles - which cannot be removed - 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 on the heap, to the point that, in current

    implementation, 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.
