% IsSceneGeometry() returns MagickTrue if the geometry is a valid scene
% specification (e.g. [1], [1-9], [1,7,4]).
%
% The format of the IsSceneGeometry method is:
%
% MagickBooleanType IsSceneGeometry(const char *geometry,
% const MagickBooleanType pedantic)
%
% A description of each parameter follows:
%
% o geometry: This string is the geometry specification.
%
% o pedantic: A value other than 0 invokes a more restrictive set of
% conditions for a valid specification (e.g. [1], [1-4], [4-1]).
