+2020-08-21 Luigi Scarso <luigi.scarso@gmail.com>
+ * Changed epsilon in binary and decimal mode from 1E-52 to
+ 2^-173 =~0.835E-52, so that mp_solve_rising_cubic now works as
+ expected.
+ * Fix @<Set the height and depth to zero if the bounding box is empty@>
+ in mp_set_text_box when height and depth are both -inf.

* better mp_snprintf macro
