This commit adds a way to debug Cycles motion blur issues which
are usually happening due to something crazy happening in between
of frames. Biggest trouble was that artists had no clue about
what's happening in subframes before they render. This is at
least inefficient workflow when dealing with motion blur shots
with complex animation.
Now there is an option in Time Line Editor which could be found
in View -> Show Subframe. This option will expose current frame
with it's subframe to the time line editor header and it'll allow
scrubbing with a subframe precision in time line editor.
Please note that none of the tools in Blender are aware of
subframe, so they'll likely be using current integer frame still.
This is something we don't consider a bug for now, the whole
purpose for now is to give a tool for investigation. Eventually
we'll likely tweak all tools to be aware of subframe.
Hopefully now we can finish the movie here in the studio..
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)
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).
This gives us 9 flags available again for properties (we had none anymore),
and also makes things slightly cleaner.
To simplify (and make more clear the differences between mere properties
and function parameters), also added RNA_def_parameter_flags function (and
its clear counterpart), to be used instead of RNA_def_property_flag for
function parameters.
This patch is also a big cleanup (some RNA function definitions were
still using 'prop' PropertyRNA pointer, etc.).
And yes, am aware this will be annoying for all branches, but we really need
to get new flags available for properties (will need at least one for override, etc.).

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.

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.

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.

At the moment light shading in Blender is produced in viewspace. Apparently, that's why
shader nodes work with normals in camera space. But it is not convenient for artists.
The more convenient approach is implemented in Cycles where normals are represented in world space.
Blend4Web Team designed the engine keeping in mind shader parameters readability,
so normals are interpreted in world space as well. And now our users have to use some tweaks, like
empty node group with the name "Replace", which is replacing one input by another on the engine side
(replacing working configuration in Blender Viewport by the configuration that has the same behavior in the engine).
This patch adds the ability to switch to world space for normals and lamp vector in BI and Viewport.
This patch is very important to us and we crave to see this patch in Blender 2.7 because
it will significantly simplify Blend4Web material creation workflow.

* Don't show name of keyframe type in timeline header. It's getting a bit too crowded
for that, so just show the keyframe icon. Hopefully that will be enough.
* Tweaked the tooltip and label to make it clearer what the setting is for
To make it easier for animators working in a multipass pose-to-pose workflow
when inserting breakdown keyframes and so forth, it is now possible to specify
the "type" of keyframe being created (i.e. the colour of the keyframe, when drawn
in the Dope Sheet).
Usage:
1) Choose the type of keyframe ("Keyframe", "Breakdown", "Extreme", etc.) from
the new dropdown located between the AutoKeying and KeyingSet widgets on the
timeline header.
2) Insert keyframes
3) Rejoyce that your newly created keyframes have now been coloured for you already
in the DopeSheet.
Todo:
* Look into a way of using the actual keyframe colours (from the theme) for the icons
of these types.
This is a new option for panorama cameras to render
stereo that can be used in virtual reality devices
The option is available under the camera panel when Multi-View is enabled (Views option in the Render Layers panel)
Known limitations:
------------------
* Parallel convergence is not supported (you need to set a convergence distance really high to simulate this effect).
* Pivot was not supposed to affect the render but it does, this has to be looked at, but for now set it to CENTER
* Derivatives in perspective camera need to be pre-computed or we shuld get rid of kcam->dx/dy (Sergey words, I don't fully grasp the implication shere)
* This works in perspective mode and in panorama mode. However, for fully benefit from this effect in perspective mode you need to render a cube map. (there is an addon for this, developed separately, perhaps we could include it in master).
* We have no support for "neck distance" at the moment. This is supposed to help with objects at short distances.
* We have no support to rotate the "Up Axis" of the stereo plane. Meaning, we hardcode 0,0,1 as UP, and create the stereo pair related to that. (although we could take the camera local UP when rendering panoramas, this wouldn't work for perspective cameras.
* We have no support for interocular distance attenuation based on the proximity of the poles (which helps to reduce the pole rotation effect/artifact).

This patch specifically dates from March 2015, as you can see in the code.blender.org post. Many thanks to all the reviewers, testers and minor sponsors who helped me maintain spherical-stereo for 1 year.
All that said, have fun with this. This feature was what got me started with Multi-View development (at the time what I was looking for was Fulldome stereo support, but the implementation is the same). In order to make this into Blender I had to make it aiming at a less-specic user-case Thus Multi-View started. (this was December 2012, during Siggraph Asia and a chat I had with Paul Bourke during the conference). I don't have the original patch anymore, but you can find a re-based version of it from March 2013, right before I start with the Multi-View project https://developer.blender.org/P332

BKE_main_id_tag_/BKE_main_id_flag_ were horrible naming now that we split those
into flags (for presistent one) and tags (for runtime ones).
Got rid of previous 'tag_' functions behavior (those who were dedicated shortcuts
to set/clear LIB_TAG_DOIT), so now '_tag_' functions affect tags, and '_flag_'
functions affect flags.
Specifically, when only one bone is selected and it's not really active.
(With multiple bones on the other hand that behavior is forced on,
since multi-paint can't modify purely zero weight verts and that's important.)
The combined pass is built with the contributions the user finds fit.
It is useful for lightmap baking, as well as non-view dependent effects
baking.
The manual will be updated once we get closer to the 2.77 release.

This is purely internal sanitizing/cleanup, no change in behavior is expected at all.
This change was also needed because we were getting short on ID flags, and
future enhancement of 'user_one' ID behavior requires two new ones.
id->flag remains for persistent data (fakeuser only, so far!), this also allows us
100% backward & forward compatibility.
New id->tag is used for most flags. Though written in .blend files, its content
is cleared at read time.
Note that .blend file version was bumped, so that we can clear runtimeflags from
old .blends, important in case we add new persistent flags in future.
Also, behavior of tags (either status ones, or whether they need to be cleared before/after use)
has been added as comments to their declaration.

The only use we had for RAS_StorageIM was to render derived meshes using
Blender's mesh drawing. This is now handled as a special case in
RAS_OpenGLRasterizer instead of in RAS_StorageIM.
We are now left with RAS_StorageVA and RAS_StorageVBO. At the moment
vertex arrays are still the default since our vertex array with display
lists implementation is still much faster than our VBO code in a lot of
cases. As we improve our VBO code, we can drop vertex arrays since
Blender's minimum OpenGL version is being bumped up to 2.1, which
supports VBOs.
This is sort of extension of existing Use Environment option which now allows to
disable AO on the render layer basis.
Useful in cases like disabling AO for the background because it might make it
too flat and so.

We have callbacks for that, they also do some checks and help ensure things are done
correctly. Only place where this is assumed not true is blenloader (since here we
may affect refcount of library IDs as well...).
Shutter curve now can be controlled using curve mapping widget in the motion
blur panel in Render buttons. Only mapping from 0..1 by x axis are allowed,
Y values will be normalized to fill in 0..1 space as well automatically.
Y values of 0 means fully closed shutter, Y values of 1 means fully opened
shutter.
Default mapping is set to old behavior when shutter opens and closes instantly.
This shutter mapping curve could easily be used by any other render engine by
accessing scene.render.motion_blur_shutter_curve.
