+Subject: [PATCH] Fix #615: gdImageStringFT() fails for empty strings as of
+ libgd 2.3.0 (#633)
+
+We change the return type of `textLayout()` to `ssize_t`, and signal
+failure by returning `-1`, so that laying out an empty string is no
+longer handled as failure.  We make sure that no overflow occurs,
+assuming that all `int` values can be fully represented as `ssize_t`.
