Although strictly the GPU fingerprint is defined by the build fingerprint, there is not currently a straightforward mapping from build fingerprint to useful GPU / GL driver information. In order to aid debugging of WebView crashes that occur in GL drivers, and to better understand the range of drivers and versions for feature blacklisting purposes, it is useful to have GPU fingerprints in breakpad microdumps. Landing this patch on behalf of Tobias Sargeant<tobiasjs@chromium.org> BUG=chromium:536769 R=primiano@chromium.org, thestig@chromium.org Review URL: https://codereview.chromium.org/1334473003 .
