1458905 - Update freetype2 to 2.9.1

Status: RESOLVED FIXED

(Core :: Graphics: Text, defect)

Description

[Tom Ritter [:tjr]]

This is a (semi-)automated bug making you aware that there is an available upgrade for an embedded third-party library. You can leave this bug open, and it will be updated if a newer version of the library becomes available. If you close it as WONTFIX, please indicate if you do not wish to receive any future bugs upon new releases of the library.

freetype2 is currently at version 2.9 in mozilla-central, and the latest version of the library released is 2.9.1. 

I fetched the latest version of the library from http://download.savannah.gnu.org/releases/freetype/.



It looks like this may be a security release, so tagging as such.

We pretty aggressively backported the upstream security fixes to 60/61 as they landed:

Tom, are you aware of any other scary-looking upstream commits that would justify taking this urgently? Otherwise, I'd prefer to wait until next week after we're clear of the Nightly soft freeze.

Nope, sounds good.

Thanks, I'll take this next week. And also, since we don't ship Android builds off ESR60, I think we can wontfix this bug for there (since it's the release we ship which uses the in-tree FT2).

Attachment: update freetype to version 2.9.1

Easy fix. Just needed to remove two files from moz.build which were added to ftbase.c as #includes instead.
