libgcc_s is not a DT_NEEDED library; it gets loaded implicitly.
This change ensures that rpath is referenced when searching for
the so. This in turn gets the resulting sky_snapshot binary
closer to being able to run in Google's production environment.
Currently, during application startup we:
* copy the FLX file to a Mojo pipe
* write the Mojo pipe contents back to a temporary file on disk
* unzip the FLX contents into cache storage
This contributes to startup latency and requires that we later clean up the
cache.
With this change, the assets will be extracted from the FLX archive
on demand with no writes to storage. Runtime cost should be minimal
given that most assets (except for the snapshot) are not compressed
in the archive.
This lets you focus and unfocus a node.
Still doesn't seem to be enough to actually have the node exposed in
TalkBack. We probably need hover for that (that's next).
(Also fixes a leak for when a subtree has been disconnected; previously
we were only forgetting the top node of the subtree, not the
descendants. Thanks @krisgiesing for catching that.)
This is another step towards enabling accessibility for Flutter on
Android. It exposes the semantics tree to Android's accessibility API
when accessibility is enabled.
It does not yet:
- allow one to actually interact with the application via the
accessibility API
- expose the accessibility tree to touch exploration
- implement the accessibility focus API
However, you can see the tree if you run uiautomatorviewer. It is there,
and it matches the UI. At least in Stocks. I didn't test anything else.
It turned out that hb_font_t creation is not a lightweight operation.
Especially, Paint.hasGlyph creates hb_font_t for all existing fonts
every time. To improve the performance, cache hb_font_t instead
of hb_face_t.
Note that to calculate horizontal advance, MinikinPaint needs to be
associated with hb_font_t by calling hb_font_set_funcs. With this patch,
hb_font_set_funcs may be called multiple times for the same hb_font_t
object. However this is not an issue since MinikinPaint is unique
during layout.

Previously we just dropped child scenes on the floor. Now we upload them
to Mozart. However, we just draw them on top of all the other content
and don't apply any clips or blends.
If the Sky shell process does not have an orderly shutdown, then temporary
files created by services may never be cleaned up.
The ResourceCleaner task will run at the next startup and clean up any files
that match the prefix used by Chromium's temporary file API. Services will
now use the same prefix for their files.
