Bug 1661624 - Include `psutil` in the `mach` `virtualenv`s r=firefox-build-system-reviewers,mhentges Install `psutil` when setting up the `mach` `virtualenv`s and stop importing the in-tree version in the build. Nothing in-tree currently assumes or mandates the installation of `psutil` (all uses of `psutil` are guarded with imports of the form `try : import psutil; except ImportError: psutil = None`), so there's no back-incompatibility concerns here. There will be an awkward period where telemetry will be lacking CPU/disk data for everyone until they re-run `mach bootstrap` or `mach create-mach-environment`, but that will come back as people gradually update their `virtualenv`s. An alternative to circumvent that issue is REQUIRING that `psutil` be installed by adding an assertion in `mach` that `psutil` can be found (allowing us to remove all the conditional logic in-tree around whether `psutil` is installed), but I wouldn't claim that we're ready to do that and deal with whatever fallout might occur.

Bug 1665461: reflect the correct colors for default themes in the skeleton UI. r=dthayer This patch supports a skeleton UI for default, light, and dark themes. It is not enabled for apenglow or any custom themes. This also takes into account the system theme. If the user has the default theme selected and is in dark mode, we override the theme and present the dark theme skeleton UI. Differential Revision: https://phabricator.services.mozilla.com/D96230

Bug 1662800 - Fix matrix multiplication order. r=botond When combining transform matrices for deferred transforms, we were multiplying them in the wrong order.

Bug 1662800 - Make the WebRenderScrollData dump nicer. r=botond This makes the WebRenderScrollData dump more analogous to the layer tree dump, in that it prints the layer entries one per line showing in-order nested tree structure.

Bug 1676717 - Don't change wpt metadata when new metadata is a subset of old, r=karlcow,denschub We often see metadata changes like [PASS, FAIL] going to [FAIL, PASS]. Although in principle we'd like the most common status to be first, when we have things like expected: [PASS, FAIL] getting lots of os-specific expectations because the frequency is different on different platforms it doesn't help much. Instead, if the new metadata is a subset of the old, bail early and don't make any changes. Differential Revision: https://phabricator.services.mozilla.com/D96750

There are a couple of others (break-before and -after for children of abs-pos elements, and some spanner tests) that don't match Chromium nor Firefox currently - these need a bit more investigation.
