8e3206382b Bug 1251995 part 2 - Add gfxTextRun::Range to replace parameter pairs like (offset, length) and (start, end). r=jfkthame 
Although this makes some places more complicated, code should generally
be simpler and clearer. It could slightly improve performance on x64 for
functions with more than four parameters, since it makes more data be
passed via registers rather than the stack.

170a29bc4a Bug 1251608 - Add a root-content annotation to the APZ test data structure. r=botond 
This patch adds the annotation in APZCTreeManager. It also changes the
tree-building code in apz_test_utils to link together the actual paint
structures rather than create new wrapper nodes. This is more foolproof
(fixes a latent bug where a grandchild node whose parent has not yet
been processed ends up with the parent forcibly made a child of the root),
and allows extra properties to seamlessly ride along into the "tree".

25a10a2d61 Bug 1219980 - Ensure that long-press gestures don't get detected during test_basic_pan.html r=botond 
Chaos mode can cause the the long-press timer to fire too early, so we have to
disable that. Also the pref to extend the timer is an int pref, not a char pref,
so drop the quotes (otherwise specialpowersAPI.js guesses the wrong type).

55594c5b97 Bug 1251886 - Correct inputFrameID selection when using e10s r=daoshengmu 
- ContainerLayerComposite::ContainerRenderVR failed to find
  a CanvasLayerComposite and get an inputFrameId as it was
  only looking at immediate children layers.
- Initialize Oculus SDK structures with 0 to ensure code is less
  brittle when Oculus SDK is updated in the future.
- Added assert and sanity check to ensure that valid inputFrameID's
  are used when indexing the Oculus pose buffers.

making the pattern GetBuffer() -> NewObjectInputStreamFromBuffer more
pleasant.

bdba733905 Bug 1250517 - Differentiate between no critical display port and empty critical display port in ClientTiledPaintedLayer; r=kats 
Currently the logic in ClientTiledPaintedLayer treats an empty critical
display port to mean that there is no critical display port, i.e. that
the entire visible region should be painted. However, the critical
displayport should be, and is, empty if either the display port or
composition bounds are entirely outwith the layer's bounds. We want to
render none of the layer in this case, not all of it.

Change BasicTiledLayerPaintData::mCriticalDisplayPort's type to a
Maybe<LayerIntRect>, and differentiate between it being not set and it
being an empty rect.
