-Fix CVE-2016-6214 (read out-of-bounds when parsing TGA files).
-
-https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-6214
-
-Adapted from upstream commit:
-https://github.com/libgd/libgd/commit/341aa68843ceceae9ba6e083431f14a07bd92308
-
-Since `patch` cannot apply Git binary diffs, we omit the addition of
-'tests/tga/bug00247a.c' and its associated binary data.

-Subject: [PATCH] Unsupported TGA bpp/alphabit combinations should error
- gracefully
-
-Currently, only 24bpp without alphabits and 32bpp with 8 alphabits are
-really supported. All other combinations will be rejected with a warning.
-
-(cherry picked from commit cb1a0b7e54e9aa118270c23a4a6fe560e4590dc9)
