Other platforms are going to need more annotations, so this allows us to
update one line while rolling out the feature, rather than updating a
bunch of test expectations. Also should be clearer.
Let me know if there are better ways to do this.

This makes it easier to play with different appearances, and it
shouldn't be significantly slower. This was useful for my investigation in
bug 1690494.

We introduce a new type of display port, a minimal display port. It is controlled via a property on the content element. When the property is present any other display port specified on the element is ignored and instead the display port rect is computed by assuming 0 display port margins and no alignment (this reuses the existing code for display port suppression).
We then add code to set a minimal display port on every scroll frame that is painted that has WantAsyncScroll() when certain prefs are set (the prefs are disabled as of this patch though).
We then need to manage removing the minimal display port property when, before this patch, we would have created a regular display port. As well we need to add the minimal display port property when, before this patch, we would have removed a regular display port.
In order to do this I audited all sites where we set the display port rect and display port margins property. The changes to the code for handling the removal display ports happens in a later patch.
My audit found that all of the places we set a display port want to clear the minimal display port property except:
-UpdateSub/RootFrame in APZCCallbackHelper
-UpdateDisplayPortMarginsForPendingMetrics in DisplayPortUtils
UpdateDisplayPortMarginsForPendingMetrics is basically a fast path of the UpdateSub/RootFrame code. These are the places where we handle calls to RequestContentRepaint from apz. By adding an assert and running it through try server I found that UpdateSub/RootFrame can create a display port in the following cases:
-a scroll info layer
-a scroll frame with !WantAsyncScroll() (the main thread never creates a display port for a scroll frame with !WantAsyncScroll()) (for example if the main thread creates a scroll id and sends over metadata via nsLayoutUtils::GetRootMetaData, and then the scroll rect changes, that will cause a RequestContentRepaint call)
-a few instances that don't fall into the above that happened on try server but didn't reproduce for me locally, so I don't know more about them.
It's not very important whether we clear the minimal display port property for these cases or not (the first two cases we don't async scroll the scroll frame at all, the last case seems quite rare).
Note that we intentionally do not change the existing behaviour of zero margin display ports set via SetZeroMarginDisplayPortOnAsyncScrollableAncestors as we are aiming for no behaviour changes with this patch (until we flip the pref). A later patch in a different bug handles changing these display ports over to minimal display ports.

Our existing batched texture upload logic works with pixel buffer objects which we don't use with ANGLE.
The motivation is to avoid expensive driver overhead from submitting many glTexSubImage2D calls (one for each texture cache item) on low-end Intel Windows configurations.
On Windows+Intel it is much faster to use batched draw calls to copy from staging textures to texture cache than using CopySubResourceRegion (when there is a high number of copies).

We can disable WebRender because the GPU process crashed, or we
encountered a graceful runtime error in WebRender. This patch adds two
new prefs to control how that fallback works.
gfx.webrender.fallback.software-d3d11 controls if WebRender falls back
to Software WebRender + D3D11 compositing. If true, and the user is
allowed to get Software WebRender, we will fallback to Software
WebRender with the D3D11 compositor first.
gfx.webrender.fallback.software controls if WebRender falls back to
Software WebRender. If true, and the user is allowed to get Software
WebRender, we will fallback to Software WebRender without the D3D11
compositor.
gfx.webrender.fallback.basic controls if WebRender or Software
WebRender falls back to Basic. If true, it falls back to Basic.
Otherwise it continues to use Software WebRender without the D3D11
compositor. Note that this means OpenGL on Android.
This patch also means that gfx.webrender.all=true and MOZ_WEBRENDER=1
no longer disables Software WebRender. It will still prefer (Hardware)
WebRender but we want to allow fallback to Software WebRender for
configurations that forced WebRender on.

Once all the remaining patches for test tweaks / fixes have landed, this
patch should be green on try. Couple test annotation changes:
* clip-003.html fails the same way it fails on mac (odd, but couldn't
repro...). I'll try to dig a bit more before calling it a day.
* radiobutton-min-size starts behaving like every other platform.
* Event-dispatch-redispatch and baseline-alignment-and-overflow start
passing.
* Couple minor fuzzy annotations (one was backwards, the other was
missing).

There are some complications here to handle unpackaged and packaged
builds. In addition, there could be a difference between App prefs
and GRE prefs. Since the underlying backgroundtasks code is built as
part of Gecko (i.e., `toolkit/...` rather than `browser/...`) I have
favoured GRE prefs. I think, however, that what is written will work
for App-specific prefs, but I'm not concerned with that detail at this
time.
This also add tests for backgroundtask-specific prefs, which are
structured as both xpcshell and mochitest-chrome tests because
locally, the former tests unpackaged builds and the latter can
accommodate testing packaged builds. We could use mochitest-chrome
for both, but this has been pleasant to work with locally.
