-Adapted from upstream commit 2bb97f407c1145c850416a3bfbcc8cf124e68a19
-(gd2: handle corrupt images better (CVE-2016-3074)).

-This patch omits the upstream changes to '.gitignore', and the test
-added in files 'tests/Makefile.am', 'tests/gd2/gd2_read_corrupt.c', and
-'tests/gd2/invalid_neg_size.gd2'.
-
-We omit the test because its input data,
-'tests/gd2/invalid_neg_size.gd2', is provided as a binary Git diff,
-which is not supported by `patch`.
