Bug 1774631 - Fix typo in cairo-pdf-surface.c that causes us to get spuriously-rasterized PDF output. r=jrmuizel, a=RyanVM

There's a typo in the condition here, which results in returning CAIRO_INT_STATUS_UNSUPPORTED
in cases where that shouldn't be necessary. Fixing this gets me nice vector PDF output.

The bug is still present in upstream cairo trunk, so I'll report it there as well.

Bug 1725145 - Preparation for the hybrid build env. r=necko-reviewers,firefox-build-system-reviewers,valentin,glandium

Automatically generated path that adds flag `REQUIRES_UNIFIED_BUILD = True` to `moz.build`
when the module governed by the build config file is not buildable outside on the unified environment.

This needs to be done in order to have a hybrid build system that adds the possibility of combing
unified build components with ones that are built outside of the unified eco system.

This implements a subset of the tag() function on the quartz surface backend;
just enough to support generating links in PDF output. In particular, the
only tag type supported is Link, and we require the link area to be passed
as a list of rects in the 'begin' call; we don't support accumulating all
drawing operations between 'begin' and 'end' into a link area.
