For example, if we set a transform to rotate3d(0, 0, 1e50, 45deg), the
expected normalized rotate axis is (0, 0, 1).
However, the length is larger than the maximum of float, so the actual value is
(0/inf, 0/inf, 1e50/inf) == (0, 0, 0). Therefore, we scale the vector before
doing normalization to avoid getting a zero vector.

- Oculus SDK was updated from 1.5 to 1.9
- As the Oculus API now returns quaternion orientations for each
eye-to-head transform, I needed to send more information to the
content process.
- Rather than adding the quaternion, we now calculate the view matrices
on the VR thread in the GPU process rather than calculating it in the
content thread from parameters.
- OpenVR's full view matrix is now used, for compatibility with more devices.
- IPD adjustments are now updated every frame for both Oculus and OpenVR.

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

These functions need to survive the gfxRect purge as they are used in a
few places.

To allow MatrixDouble to be a drop-in replacement for gfxMatrix, it
needs to accept the "double" versions of Point, Rect, and Size. This
patch does that by adding some extra typedefs inside BaseMatrix to
abstract over that.
It also moves some function implementations into the .h file as they
don't need specialization. I left some function implementations in
the Matrix.cpp file:
- Rotation, because it is specialized for Float and Double, since it uses
sinf/cosf vs sin/cos in the two implementations.
- The Matrix4x4 multiplication operator overload, because if I put it
inside the BaseMatrix class declaration Matrix4x4 isn't defined yet
and the compiler doesn't like it.

This extracts a BaseMatrix template of which Matrix is now a particular
specialization. The BaseMatrix allows us to reuse the same code for
floats and doubles, much like the other "base" classes (BasePoint,
BaseRect, etc.).

- Adding an array member to access the components of vector, size,
and matrix classes reduces the code needed when passing all of the
members to functions.

Matrix4x4 remains a typedef for Matrix4x4Typed<UnknownUnits, UnknownUnits>.
No client code needed changing, except for forward-declarations of Matrix4x4
as a class (since it's now a typedef).

- Added specialized rect clipping functionality to Matrix4x4::ProjectRectBounds
so we don't have to return infinite values when rects cross the w=0 plane
in homogenous coordinate space.
- Updated callsites of ProjectRectBounds to pass a clipping rect that is
appropriate for the units that are returned.
