* gtk_symbolic_color_resolve:
* @color: a #GtkSymbolicColor
* @props: (allow-none): #GtkStyleProperties to use when resolving
* named colors, or %NULL
* @resolved_color: (out): return location for the resolved color
*
* If @color is resolvable, @resolved_color will be filled in
* with the resolved color, and %TRUE will be returned. Generally,
* if @color can't be resolved, it is due to it being defined on
* top of a named color that doesn't exist in @props.
*
* When @props is %NULL, resolving of named colors will fail, so if
* your @color is or references such a color, this function will
* return %FALSE.
*
* Returns: %TRUE if the color has been resolved
*
* Since: 3.0
*
* Deprecated: 3.8: #GtkSymbolicColor is deprecated.
