% MagickQueryMultilineFontMetrics() returns a 13 element array representing the
% following font metrics:
%
% Element Description
% -------------------------------------------------
% 0 character width
% 1 character height
% 2 ascender
% 3 descender
% 4 text width
% 5 text height
% 6 maximum horizontal advance
% 7 bounding box: x1
% 8 bounding box: y1
% 9 bounding box: x2
% 10 bounding box: y2
% 11 origin: x
% 12 origin: y
%
% This method is like MagickQueryFontMetrics() but it returns the maximum text
% width and height for multiple lines of text.
%
% The format of the MagickQueryFontMetrics method is:
%
% double *MagickQueryMultilineFontMetrics(MagickWand *wand,
% const DrawingWand *drawing_wand,const char *text)
%
% A description of each parameter follows:
%
% o wand: the Magick wand.
%
% o drawing_wand: the drawing wand.
%
% o text: the text.
