mdraw_per_char_extents - Obtain per character dimension information.
Obtain per character dimension information.
The mdraw_per_char_extents() function computes the text dimension of each
character in M-text mt .
The faces given as text properties in mt and
the default face of frame frame determine the fonts to draw the text. Each
successive element in array_return is set to the drawn metrics of successive
characters, which is relative to the origin of the drawing, and a rectangle
for each character in mt .
The number of elements of array_return must
be equal to or greater than the number of characters in mt .
If pointer overall_return is not NULL ,
this function also computes the
extents of the overall text and stores the results in the members of the
structure pointed to by overall_return .
