Avoids possible jumps when one is trying to do some really preciese tweak.
Quite striaghtforward change for mouse input initialization: take Shift
state into account. However, this will interfere with the axis exclusion
which is currently also uses Shift (the feature to move something in a
plane which doesn't have selected axis). This is probably not so commonly
used feature (nobody in the studio even knew of it) and the only downside
now would be that such a constrainted movement will become accurate by
default. That's easy to deal from user side by just unholding Shift key.

To make it faster to try different interpolation curves, there's a new operator
"Remove Breakdowns" which will delete all breakdowns sandwiched by normal
keyframes (i.e. all the ones that the previous run of the Interpolation op created)
This commit introduces the ability to use the Robert Penner easing equations
or a Custom Curve to control the way that the "Interpolate Sequence" operator
interpolates between keyframes. Previously, it was only possible to get linear
interpolation between the gp frames.
Workflow:
1) Place current frame between a pair of GP keyframes
2) Open the "Interpolate" panel in the Toolshelf
3) Choose the interpolation type (under "Sequence Options")
4) Adjust settings (e.g. if you're using "Custom Curve", use the curvemap widget
to define the way that the interpolation proceeds)
5) Click "Sequence" to interpolate
6) Play back/scrub the animation to see if you've got the result you want
7) If you need to make some tweaks, undo, or delete the generated keyframes,
then repeat the process again from step 4 until you've got the desired result.
The "gp_sculpt" settings should be strictly for stroke sculpting, and not abused by
other tools. (Similarly, if other general GP tools need one-off options, those should
go into the normal toolsettings->gpencil_flag)
Furthermore, this paves the way for introducing new settings for controlling the way
that GP interpolation takes place (e.g. with easing equations, or a custom curvemap)
* Reshuffled some blocks of code for better ease of navigation/flow in the file
* Improved some tooltips
* Removed "Helper" tag from some functions that serve bigger roles
* Fixed some errant formatting
The interpolation operators (and their associated code) occupied a significant
portion of gpencil_edit.c (which was getting a bit heavy). So, it's best to split
these out into a separate file to make things easier to handle, in preparation
for some further dev work.
Things like `BLI_uniquename` had nothing, but really nothing to do in
BLI_path_util files!
Also, got rid of length limitation in `BLI_uniquename_cb`, we can use
alloca here to avoid overhead of malloc while keeping free size (within
reasonable limits of course).
Just store bones that could not get renamed to desired flipped name on the
first try into a temp list, and try to rename them a second time.
This is rather simple solution, will induce 'over numbering' in case you
flip a bone to another unselected bone's name (since number will be
incremented in both rename attempts), but think this is acceptable minor
glitch, for a corner case situation that does not have any good
resolution anyway.
Also, set `strip_numbers` option of `BKE_deform_flip_side_name` to
false, otherwise chains of bones with same names would get their numbers
completely messed up after name flipping.
Based on work by @dfelinto in D2456 (https://developer.blender.org/D2456), thanks.
This adds two functions to project 3d coordinates onto a 3d plane,
to get 2d coordinates, essentially eliminating the plane's normal axis
from the coordinates.

It is quite likely in a triangulated mesh that the actual island edge
belongs to a different triangle than the current pixel; for example
consider corners of a triangulated axis aligned rectangle face that
have the additional edge: a pixel there will have to be assigned to
one of the triangles, but one of the edges of the original rectangle
can only be accessed through the other triangle.
Thus for robust operation it is necessary to do a recursive search.
The search is limited by requiring that it only goes through edges
that bring it closer to the target point, and also by depth as a
safeguard.

The code requires the pixel on the other side of the seam to be assigned
precisely to the expected triangle. This can cause false negatives around
vertices, where a pixel is likely to touch multiple triangles and thus
cannot be said to unambiguously belong to any one of them, so check
distance to the intended triangle and accept the result if it's close.
1. Forcibly symmetrize the neighbor relations, so that if A is neighbor
of B, B is neighbor of A. The existing code is guaranteed to violate
this if texture resolution is different between the sides of a seam.
2. In texture mode dynamic paint adds a 1 pixel wide border around the
islands. These pixels aren't really part of the dynamic paint domain
and thus by design can't have symmetrical neighbor relations. This
means they can't be treated by effects like normal pixels.
The simplest way to handle it in a consistent way is to exclude
them from effects, but add an additional pass that recomputes them
as average of their non-border neighbors, located on both sides of
the seam.
This avoids intersection AABB of different curve primitives
which makes it less ray-to-primitive intersections.
This gives about 30% speedup of hair rendering in the barber
shop scenes here. There is still some work to be done on those
files to solve major speed issues on certain frames.
This way we can have different limits for regular and motion curves
which we'll do in one of the upcoming commits in order to gain some
percents of speedup.
The reasoning here is that motion curves are usually intersecting
lots of others bounding boxes, which makes it inefficient to have
single primitive in the leaf node.
Maximal number of elements is supposed to be inclusive. That is what
it was always meant in this file and what @brecht considered still
the case in 6974b69c61.
In fact, the commit message to that change mentions that we allowed
up to 2 curve primitives per leaf while in fact it was doing up to 1
curve primitive.
Making it real 2 primitives at a max gives about 5% slowdown for the
koro.blend scene. This is a reason why BVHParams.max_curve_leaf_size
was changed to 1 by this change.
Since the beginning of times hair settings in cycles were global for
the whole scene but were located in the particle context. This causes
quite some trickery to get shots set up for the movies here in the
studio by forcing artists to create dummy particle system to change
settings of hair on the shot.
While ideally this settings should be properly become per-particle
system for the time being it will save sweat and blood to move the
settings to scene context.

Made them closer to how GTest shows the output, so reading test logs
is easier now (at least feels more uniform).
Additionally now we know how much time tests are taking so can tweak
samples/resolution to reduce render time of slow tests.
It is now also possible to enable colored messages using magic
CYCLESTEST_COLOR environment variable. This makes it even easier to
visually grep failed/passed tests using `ctest -R cycles -V`.
Reusing PROP_TEXTEDIT_UPDATE instead of adding a new property flag just for search strings. Currently it's only used for search strings anyway so seems fine for now.
Fixes T50336.
This splits `interp_weights_face_v3` into `interp_weights_tri_v3` and
`interp_weights_quad_v3`, in order to properly handle three sided polygons
without needing a useless extra index in your weight array. This also
improves clarity and consistency with other math_geom functions, thus
reducing potential future errors.

The issue was that we used to compare number of vertices for mesh after the auto
smooth was applied (at the center of the shutter time) with number of vertices
prior to the auto smooth applied. This caused false-positive consideration of a
mesh as changing topology.
Now we do autosplit as early as possible and do it from blender side, so Cycles
does not need to re-implement splitting on it's side.
