This patch implements the matrix types (i.e:float4x4) by making heavy
usage of templating. All matrix functions are now outside of the vector
classes (inside the blender::math namespace) and are not vector size
dependent for the most part.
###Motivations
The goal/motivations of this rewrite are the same as the Vector C++ API (D13791):
- Template everything for making it work with any types and avoid code duplication.
- Use functional style instead of Object Oriented function call to allow a simple compatibility layer with GLSL syntax (see T103026 for more details).
- Allow most convenient constructor syntax and accessors (array subscript `matrix[c][r]`, or component alias `matrix.y.z`).
- Make it cover all features the current C API supports for adoption.
- Keep compilation time and debug performance somehow acceptable.
###Consideration:
- The new `MatView` class can be generated by `my_float.view<NumCol, NumRow, StartCol, StartRow>()` (with the last 2 being optionnal). This one allows modifying parts of the source matrix in place. It isn't pretty and duplicates a lot of code, but it is needed mainly to replace `normalize_m4`. At least I think it is a good starting point that can refined further.
- An exhaustive list of missing `BLI_math_matrix.h` functions from the new API can be found here P3373.
- This adds new Rotation types in order to have a clean API. This will be extended when we port the full Rotation API. The types are made so that they don't allow implicit down-casting to their vector representation.
- Some functions make direct use of the Eigen library, bypassing the Eigen C API defined in `intern/eigen`. Its use is contained inside `math_matrix.cc`. There is conflicting opinion wether we should use it more so I contained its usage to almost the tasks as in the C API for now.

Both cloth object collision and self collision use a BVH tree
representing the current cloth shape. The only difference between
them is the epsilon threshold value.
If these values are the same, it is possible to use the same tree
for both uses, thus easily reducing the overhead in the case when
both collision modes are used by the same cloth object.

Socket locations are set while drawing the node tree in the editor.
They can always be recalculated this way based on the node position and
other factors. Storing them in the socket is misleading. Plus, ideally
sockets would be quite small to store, this helps us move in that
direction.
Now the socket locations are stored as runtime data of the node editor,
making use of the new node topology cache's `index_in_tree` function
to make a SoA layout possible.

This patch allows the realtime compositor to be limited to a specific
compositing region that is a subset of the full render region. In the
context of the viewport compositor, when the viewport is in camera view
and has a completely opaque passepartout, the compositing region will be
limited to the visible camera region.
On the user-level, this gives the user the ability to make the result of
the compositor invariant of the aspect ratio, shift, and zoom of the
viewport, making the result in the viewport identical to the final
render compositor assuming size relative operations.
It should be noted that compositing region is the *visible* camera
region, that is, the result of the intersection of the camera region and
the render region. So the user should be careful not to shift or zoom
the view such that the camera border extends outside of the viewport to
have the aforementioned benefits. While we could implement logic to fill
the areas outside of the render region with zeros in some cases, there
are many other ambiguous cases where such a solution wouldn't work,
including the problematic case where the user zooms in very close,
making the camera region much bigger than that of the render region.

Ideally, we would also get variance information out of the test, but that
seems a bit more complex to implement. For now just run the test a couple
of times and average the timings.
The test now runs between 5 and 100 times, depending on how long it
to run the test once.
I noticed that sometimes the geometry nodes benchmark would not work
if there were some left-over debug prints in the code. The reason it did
not work was because the prints were mixed with the test output print.
I also tried using explicit flusing and `atexit` for printing the test output,
but that didn't solve it. Just printing additional newlines to better separate
the test output from other printed output helped though.
Using negative blend factors for blending in flipped poses was undesirable.
Instead, the pose blending operator now uses CTRL to flip the pose.
Negative blend values are still allowed, and cause the pose asset to be
subtracted from the current pose. It can quickly break the rig, but for
small adjustments it can be useful.
The slider component can now be told to not use CTRL for toggling stepped
10% increments. This is useful when the operator that uses the slider needs
that modifier key for its own purposes.
Initial error caused by 1efc94bb2f and fixed in 6a7917162c. However
the empty index files (empty as in, they contain the version number but
no assets) will have to be fixed somehow, since otherwise assets don't
show up at all for people who saved asset files in a broken version.
Delete empty index files if the modification timestamp indicates a time
when the bug was present (plus a day before and after, to address
possible time zone differences). This will basically make Blender skip
the optimization for .blend files without assets for one load, but even
then the index should still produce faster results than a completely
non-index read.
This can be removed after a while, it's just a (much needed) fix for
people who were using alpha/beta builds.

The use of `std::variant` allows combining the four vectors

`std::get` is only available since macOS 10.14.
Issue comes from the fact that some of the image updates are handled
outside of depsgraph context (through the signal system), and therefore
completely ignored by the undo/redo code.
Now that undo/redo tries to update as little data as possible, it needs
to be aware of these changes.
As a temporary workaround, until image update is fully handled through depsgraph,
consider that IDs tagged with `ID_RECALC_SOURCE` should get their caches
cleared on undo/redo, and tag some RNA property updates of
Image/ColorSpace as such.

- Add parentheses to suppress an assertion on some compilers.
- It turns out cloth self-collision math is not precisely symmetric,
so sort the triangle index pair to restore behavior exactly identical
to the version before the new traversal.
Follow up to rB0796210c8df32
Previously cloth self-collision and other code that wants self-overlap
data was using an ordinary BVH overlap utility function. This works,
but is suboptimal because it fails to take advantage of the fact that
it is comparing two identical trees.
The standard traversal for self-collision essentially devolves into
enumerating all elements of the tree, and then matching them to the
tree starting at the root. However, the tree itself naturally partitions
the space, so overlapping elements are likely to be mostly placed nearby
in the tree structure as well.
Instead, self-overlap can be computed by recursively computing ordinary
overlap between siblings within each subtree. This only considers each
pair of leaves once, and provides significantly better locality.
It also avoids outputting every overlap pair twice in different order.

This patch adds two new panels in which users can control
offset (position, rotation, scale) by layer and by stroke number.
Use cases:
- if you want to create array of Suzannes and place them one behind
another, in 2d mode, Z depth will be wrong.
In 3d mode there will be Z fighting. With combination of stroke
and layer offset we can fight this issue without touching original drawing.
- even easier way to create 2.5d environments..
simply draw on layers and then displace them in one panel
instead fiddling with every layer individually
Possible improvements:
- add offset by material slot
- add step parameter, to allow displacing groups of N strokes.

Since rBcommit 74c4977a the pose library blending operator can extrapolate.
This is now also reflected in the hard min/max value of the blend factor
RNA property. The soft min/max are still -1/1 to indicate normal use.
While blending, press E to enable extrapolation / overshoot of the pose.
It will make it possible to blend in more than 100% of the pose asset.
This has the potential to completely break the rig, but it can be useful
to exaggerate poses when used with caution.
This was the case when an Annotation is also present as in the report.
Since {rB92d7f9ac56e0}, Dopesheet is aware of greaspencil/annotations
(displays its channels/keyframes, can rename their data, layers, fcurve
groupings etc.). However, the Graph Editor does not display these /
should not be aware of them.
Above commit already had issues that were addressed in the following
commits (mostly adding the new `ANIMFILTER_FCURVESONLY` to places that
dont handle greasepencil/annotations)
- {rBfdf34666f00f}
- {rB45f483681fef}
- {rBa26038ff3851}
Now in T103303 it was reported that doublicking a channel would not
select all fcurve`s keyframes anymore and this wasnt actually an issue
with that particular operator, but instead with another operator that is
also mapped to doubleclicking: the channel renaming (I assume the
keyconflict here is actually wanted behavior).
Channel renaming would not return `OPERATOR_PASS_THROUGH` here anymore
in the case nothing cannot be renamed, so we would not actually reach
the 2nd operator at all (the one selecting all keyframes).
Deeper reason for this is that the renaming operator would actually
"see" a channel that could be renamed (in the case of the report: an
annotation layer), but then cannot proceed, because the "real"
underlying data where the doubleclick happens is an fcurve...
So now exclude non-greasepencil channels in filtering as well where
appropriate by also adding `ANIMFILTER_FCURVESONLY` to the filter there.

Multiframe copy paste operations were prohibited by a block of code.
While this is understandable as it prevents confusing actions, there is a good use case to allow multiframe copy pasting.
This patch does:
- remove restricting block of code
- adds outer loops for frames both in copy and paste actions.
In copy action it will create an array of selected strokes from all selected frames
In paste action it will create new from previous copy action merged to a single frame. It will paste to all selected frames and create new frame if autokey is on and time cursor is not on any of the keyframes.
The main usecase is for creating motion smears as in examples attached. The user still need to do some actions in order to achieve desired look, such as stroke ordering and deleting excessive strokes.
