[ft-devel] FreeType into Chromium autoroller

[Ben Wagner]

At [0] there is now an autoroller from Chromium's mirror of the
FreeType repository [1] into Chromium. This autoroller will normally
be in dry-run mode for rolling tip of tree FreeType into Chromium, so
it will run the Chromium / Blink tests against tip of tree (both
Chromium and FreeType), but will still need manual approval to
actually land the rolls. The history of rolls for this autoroller can
be found at [2] . Note that manual rolls (like the one that just
landed) won't show up there, a search like [3] will list all of them.

Note that it probably won't be super fast to pick up on FreeType
changes, since the mirror will need to pick up the change, then the
autoroller will need to notice it, and then the builds and tests
actually run. However, this should still make it much easier for
Chromium to keep up, as well as provide some automatic testing for
changes in FreeType, allowing for early notice of potential issues.
Note that Chromium doesn't build all of FreeType and the tests don't
attempt to try all the possible interesting combinations of FreeType
font / glyph loading flags, so this won't catch everything but it
should point out when most things go wonky. (All the things Chromium
complains about when doing a roll.)

This makes rolling easier for Chromium, but we also hope this is
useful to FreeType development. If there are any issues with
permissions or being able to see enough interesting information
through these links, let us know.
