Since the collision modifier cannot be disabled, it causes a constant
hit on the viewport animation playback FPS. Most of this overhead can
be automatically removed in the case when the collider is static.
The updates are only skipped when the collider was stationary during
the preceding update as well, so the state is stored in a field.
Knowing that the collider is static can also be used to disable similar
BVH updates for substeps in the actual cloth simulation code.

This basically exposes to the UI a function that was only available
through a debug macro ; the purpose is obviously to help debugging
simulations. It adds ways to draw the vectors either as colored needles
or as arrows showing the direction of the vectors. The colors are based
on the magnitude of the underlying vectors.

Current approach uses view aligned slicing to generate polygons for GL
texturing such that the generated polygons are always facing the view
plane. Now it is also possible to use object aligned slicing, which
creates polygons by slicing the object perpendicular to whichever axis
is facing the most the view plane. It is also possible to create a
single slice for inspecting the volume, or for 2D rendering effects.
Settings for this, along with a density multiplier setting, are to be
found in a newly added "Smoke Display Settings" panel in the smoke
domain properties tab.

Drawing used colors for select (TH_EDGE_SELECT/TH_VERTEX_SELECT) which was inconsistent with crease, seam, sharp, .. (which all had their own them color -- also was a bit hard to read).
NOTE: UI team usually doesn't allow adding more theme options, this is an exception.

This patch changes a couple of things in the video output encoding.
{F362527}
- Clearer separation between container and codec. No more "format", as this is
too ambiguous. As a result, codecs were removed from the container list.
- Added FFmpeg speed presets, so the user can choosen from the range "Very
slow" to "Ultra fast". By default no preset is used.
- Added Constant Rate Factor (CRF) mode, which allows changing the bit-rate
depending on the desired quality and the input. This generally produces the
best quality videos, at the expense of not knowing the exact bit-rate and
file size.
- Added optional maximum of non-B-frames between B-frames (`max_b_frames`).
- Presets were adjusted for these changes, and new presets added. One of the
new presets is [recommended](https://trac.ffmpeg.org/wiki/Encode/VFX#H.264)
for reviewing videos, as it allows players to scrub through it easily. Might
be nice in weeklies. This preset also requires control over the
`max_b_frames` setting.
GUI-only changes:
- Renamed "MPEG" in the output file format menu with "FFmpeg", as this is more
accurate. After all, FFmpeg is used when this option is chosen, which can
also output non-MPEG files.
- Certain parts of the GUI are disabled when not in use:
- bit rate options are not used when a constant rate factor is given.
- audio bitrate & volume are not used when no audio is exported.
Note that I did not touch `BKE_ffmpeg_preset_set()`. There are currently two
preset systems for FFmpeg (`BKE_ffmpeg_preset_set()` and the Python preset
system). Before we do more work on `BKE_ffmpeg_preset_set()`, I think it's a
good idea to determine whether we want to keep it at all.
After this patch has been accepted, I'd be happy to go through the code and
remove any then-obsolete bits, such as the handling of "XVID" as a container
format.

The idea is to allow certain animation channels to be always visible in
animation editors. So, for example, one can pin Camera animation to the
editor so it is always possible to refine/tweak camera animation when
animating something else in the scene.
There is probably some more polishing required, and some current
limitations could be solved in the future but should be a good starting
point already.
Currently only works for object without recursing into deeper datablock
(so for example, it's not possible to pin object material animation).

Two new modal operators to create a grease pencil interpolate drawing
for one frame or a complete sequence between two frames. For drawing
the temporary strokes in the viewport, two drawing handlers have been
added to manage 3D and 2D stuff.
Video: https://youtu.be/qxYwO5sSg5Y
The operator shortcuts are Ctrl+E and Ctrl+Shift+E. During the modal
operator, the interpolation can be adjusted using the mouse (moving
left/right) or the wheel mouse.

When using metadata stamping, it's often handy to have "Camera" in
front of the camera name, "Marker" in front of the marker text, etc.,
but sometimes those get in the way. This patch allows an artist to
turn those labels on/off.

Multiple threads could create multiple handles for the same cache file,
so protect handle creation with a mutex, to make sure only one is
created.

For now simply reshuffle option so they keep proper dependency flow.
Benefits:
- Has an ability to hide tracks lists to work with other sliders around.
Could be really handy to quickly get rid of lenghty lists.
- From a feedback seems to be fitting workflow better.
Things to doublecheck on:
- Feels a bit misordered: first you define whether one want to have
rotation stabilized, then have tracks, then scale options.
While this follows dependency flow (which is really good and which
we should not violate) it has weird feeling on whether things are
really where they have to be.
- Autoscale controls visibility of max-scale, can we just make it
active/inactive instead?
- Autoscale replaces slider with label. Can it be disabled slider
instead to reduce visual jumping (disabled slider prevents user
input)
Hopefully we'll still want to have collapsable box after re-iterating
over this points, so we don't waste bits in DNA.

See this page for motivation and description of concepts:
https://github.com/Ichthyostega/blender/wiki
See this video for UI explanation and demonstration of usage
http://vimeo.com/blenderHack/stabilizerdemo
This proposal attempts to improve usability of Blender's image stabilization
feature for real-world footage esp. with moving and panning camera. It builds
upon the feature tracking to get a measurement of 2D image movement.
- Use a weighted average of movement contributions (instead of a median).
- Allow for rotation compensation and zoom (image scale) compensation.
- Allow to pick a different set of tracks for translation and for
rotation/zoom.
- Treat translation / rotation / zoom contributions systematically in a
similar way.
- Improve handling of partial tracking data with gaps and varying
start / end points.
- Have a user definable anchor frame and interpolate / extrapolate data to
avoid jumping back to "neutral" position when no tracking data is available.
- Support for travelling and panning shots by including an //intended//
position/rotation/zoom ("target position"). The idea is for these parameters
to be //animated// by the user, in order to supply an smooth, intended
camera movement. This way, we can keep the image content roughly in frame
even when moving completely away from the initial view.
A known shortcoming is that the pivot point for rotation compensation is set to
the translation compensated image center. This can produce spurious rotation on
travelling shots, which needs to be compensated manually (by animating the
target rotation parameter). There are several possible ways to address that
problem, yet all of them are considered beyond the scope of this improvement
proposal for now.
Own modifications:
- Restrict line length, it's really handy for split-view editing
- In motion tracking we prefer fully human-readable comments, meaning we
don't use doxygen with it's weird markup and comments are supposed to
start with capital and end with a full stop,
- Add explicit comparison of pointer to NULL.

The first character of the ID type was used to tag IDs for updates which
is weak since different IDs can have the same first character (for
example meshes, materials and metaballs), causing unnecessary updates of
unrelated IDs.
Now we use a unique index per ID type to tag for updates, unifying IDs
arrays indexing along the way.

All in all, this patch adds an Alembic importer, an Alembic exporter,
and a new CacheFile data block which, for now, wraps around an Alembic
archive. This data block is made available through a new modifier ("Mesh
Sequence Cache") as well as a new constraint ("Transform Cache") to
somewhat properly support respectively geometric and transformation data
streaming from alembic caches.
A more in-depth documentation is to be found on the wiki, as well as a
guide to compile alembic: https://wiki.blender.org/index.php/
User:Kevindietrich/AlembicBasicIo.
Many thanks to everyone involved in this little project, and huge shout
out to "cgstrive" for the thorough testings with Maya, 3ds Max, Houdini
and Realflow as well as @fjuhec, @jensverwiebe and @jasperge for the
custom builds and compile fixes.

This diff adds a 6th drawing mode to the Waveform Scope.
The new mode shows the RGB colour channels overlaid as a "Full colour" waveform.
The old "Red Green Blue" mode is renamed "Parade" which is the standard industry
term for RGB channels shown side-by-side.
This full colour style of waveform is very much more useful for colour grading than the
Parade mode and is the default waveform for many artists.
Files from older Blender versions which show scopes open as expected.

Applying cflags globally can be problematic especially with extern, intern libs.
Now flags from target named will be used when defined,
allowing for developers to define flags for modules they maintain.
Convention is CMAKE_CFLAGS_${UPPERCASE_TARGET_NAME}, (CXXFLAGS for C++).
eg: CMAKE_CFLAGS_BF_BLENDER, CMAKE_CFLAGS_MAKESDNA, CMAKE_CXXFLAGS_CYCLES_KERNEL
On Linux run `make help` for full list of names, MSVC shows these in the solution.

Currently "long keyframes" are only useful for indicating where stationary
holds occur. If however you try to create a "moving hold" (where the values
are slightly different, but in terms of overall effect, it's still a hold)
then it could get tricky to keep track of where these occur.
Now it's possible to tag such keyframes (using the keyframe types - RKEY)
as being part of a moving hold. These will not only be drawn differently
from normal keyframes, but they will also result in a "long keyframe"
being drawn between each pair of them, just like if they had been completely
stationary instead.
Currently the theming/styling of these is a bit rough. They reuse the existing
theme colours for long keyframes.

A long requested feature has been to have objects appear in alphabetical order
in the animation editors, so that it is easier to find where they occur. This
commit implements support for this.
The main sticking point has been the performance impact of having this sorting
happening all the time (as the actual list of "bases" cannot be modified, as the
old depsgraph still needs random-looking unsorted order of objects for scheduling
updates). However, it recently occurred to me that perhaps by restricting it to
the one case where the ordering actually matters (i.e. when we're getting the channel
list for drawing all channels, vs operating on them), and adding a toggle to turn the
sorting off in heavy scenes when it might bog down things, that it will probably
be acceptable enough in general. Furthermore, if things get really bad, we can investigate
putting in place some sort of caching scheme for this too - though hopefully the
new depsgraph will make that unnecessary (i.e. it doesn't sort the bases directly anymore).
|

This commit introduces a scale factor setting for scaling all keyframe indicators
in the Dopesheet Editor up/down, in order to make them easier to select. It is perhaps
most useful for keyframe types which are usually indicated using smaller keyframes
(e.g. breakdown), which may get tricky to quickly select.

To make it easier to synchronise timing across multiple strips, if you add
markers locally to an action, these will show up in the NLA strip in the
NLA Editor. These markings can then be used to line up the start/end of
another strip, or even to make sure that the markers from two different
strips end up lining up.
By default, this is turned on, but it can be disabled (via the View menu)
if it adds too much visual noise.

Since SDNA was allocated for each undo step,
the new address meant it was considered different and included again.
Add an option not to duplicate the DNA string when calling DNA_sdna_from_data,
as well as avoiding a redundant copy, it writes the same address each time.

Idea is to replace hard-to-track (id->lib != NULL) 'is linked datablock' check everywhere in Blender
by a macro doing the same thing. This will allow to easily spot those checks in future, and more importantly,
to easily change it (see work done in asset-engine branch).
Note: did not touch to readfile.c, since there most of the time 'id->lib' check actually concerns the pointer,
and not a check whether ID is linked or not. Will have a closer look at it later.

Environment lighting (aka ambient) is a key component of any renderer.
It's implemented like the Environment lighting of BI render for Approximate Gather mode. It support "Sky Color" and "White" Environment lighting modes.
It would be great if the user could see actual lighting conditions right in the Blender viewport instead of waiting for the renderer to complete the final image, exporting for external renderer or for a game engine.
