| const |
returns font metrics of a substring that verifies certain conditions.
Notes:
- the substring starts from the beginning of 'str' and ends at the 1st
or 1st " " that is before 'available_width'.
- it is equal to 'str' otherwise.
- returns w and h that this substring occupies and its length 'sublen'
- change_line = 1 si line must be changed because of size and 2 if a
was found
