This is an experimental option that I found would have been useful to have,
when making my earlier anim test. The only contentious point is whether it's
better to use a separate boolean flag (perhaps bound to the labels) instead
of overloading this setting (and describing the usage in the tooltip).
After some test, a new iteration parameter has been added in order to
apply repetitive smoothing to the stroke. By default 1 iteration is applied,
but can used any number between 1 and 3.
The repetition uses different levels of intensity from 100% of the defined smooth
factor for the first loop, 50% for the second and 25% for the third. We use in each
loop a smaller value in order to avoid deform too much the stroke.
Improve filling for concave shapes using a triangulation of the stroke.
The triangulation information is saved in an internal cache and only is
recalculated if the stroke changes.
The triangulation is not saved in .blend file.

Separate the creation of trees from EditMesh from the creation of trees from DerivedMesh.
This was meant to simplify the API, but didn't work out so well.
`bvhtree_from_mesh_*` actually is working as `bvhtree_from_derivedmesh_*`.
This is inconsistent with the trees created from EditMesh. Since for create them does not use the DerivedMesh.
In such cases the dm is being used only to cache the tree in the struct DerivedMesh. What is immediately released once
bvhtree is being used in functions that change(tag) the DM cleaning the cache.
- Use a filter function so users of SnapObjectContext can define how edit-mesh elements are handled.
- Remove em_evil.
- bvhtree of EditMesh is now really cached in the snap functions.
- Code becomes organized and easier to maintain.
This is an important patch for future improvements in snapping functions.
Now CD_SHAPEKEY_INDEX customdata is stored in edit-mode when hooks and vertex parents are used.
This also fixes a bug where undo would loose key-index data.
Move to structs for BM_mesh_bm_to/from_me to avoid passing many argument, which mostly aren't used.
This fixes a lot of things in NLA RNA update handling (which basically did not update anything previously).
There are more update issues with this editor though...
This introduces a snap-context that can be re-used for casting rays into the scene
(by operators such as walk-mode, ruler and transform code).
This can be used to cache data between calls too.
* Knock out "Python" FModifier entry - It really hasn't been coded yet!
* Add icon for "Match Indices" driver eyedropper mode. It should help provide
a bit more of a hint of what it does, but it also doesn't look quite as nice now.
This commit aims to streamline the driver variables layout a bit
* Each variable type now has an icon. (The loc diff and rot diff ones are placeholders,
which could deserve something better/dedicated if we continue to use this)
* Instead of taking up an entire row, the variable type dropdown now only shows
an icon, and is located before the variable name field.
Feedback wanted: Is this more/less confusing than it was?
Simple solution is to get rid of this stupid `rna_TextureSlot_brush_update` func, and do what it was doing directly
in BR case of `rna_TextureSlot_update`. That way, all updates to brush texture will invalidate correctly the overlay.
Note that this double definition of texture pointer for brushes looks rather fishy, am really not convinced this helps
keeping things simple and clear at all (what happened here is that texture selector in image paint editor was using
'texture' member of brush itself, which was performing correct RNA update, while context-based brush texture selector
from buttons space was using 'texture' member of the TextureSlot struct, which had default texture update callback
which was not invalidating overlay).
- Access with Shift-LMB or from the 'Create' toolbar tab.
- Uses curve fitting for bezier curves, with error and corner angle options.
- Optional tablet pressure to curve radius mapping.
- Depth can use the cursor or optionally draw onto the surface,
for the entire stroke or using the stroke start.
- Stroke plane can optionally be perpendicular to, or aligned to the surface normal.
- Optional radius tapering and for start/end points.
- Supports operator redo and calling from Python.
Similar to velocity, it was kind of supported by the mesh manager but
was missing a code in BlenderSession to get actual values.
In Cycles Heat is an attribute which goes from -1 to 1, where -1 is
the coldest ever temperature, 1 is the hottest ever one.
This was a feature request from a few years back (IIRC from ZanQdo?) to make it
easier to reuse one set of driver variables across several different drivers.
Dev Notes:
* Finally it's done! All that trouble for two little buttons.
* Grr... cmake... grrr!
This patch depends on D1747, which upgrades the Recast version. It exposes the new Recast partitioning methods in the navmesh generation.

The improved Hosek / Wilkie model was added during my GSoC 2013 and the default since then.
The older model was kinda kept for compatibility, but after more than 2 years it's time to remove it.
The Hosek / Wilkie model is more realistic anyway, and people who really want a day / night transition can mix the Sky Shader with another one (e.g. color) and fade between the two.
This never really worked that well, and often ended up being far too strong
to be of practical use. The new options do similar things, but with greater
control, so removing this old method now.
On second thought, these might be better names for these... I'm still not 100%
happy with these, but they will do for now.
(Best results currently seem to be with smooth 0.7, and subdivision steps 1 or 2)
Improve the quality of current grease pencil strokes adding a new dynamic smooth and subdivision. The level of smooth and subdivide can be adjusted using UI parameters. These options are disabled by default in order to keep the grease pencil stroke compatible with any existing add-on.
Both parameters are defined at layer level.

This patch adds support for coloring point density textures based on several mesh vertex attributes.
* Vertex Color: Use a vertex color layer for coloring the point density texture
* Vertex Weight: Use a weights from a vertex group as intensity values. (for Blender Render engine the additional color band is used)
* Vertex Normals: Use object-space vertex normals as RGB values.
The vertex color source enum is stored separately from the particle color source, to avoid invalid values when switching.
Note that vertex colors are technically "corner colors" (MLoop), so each vertex can have as many colors as faces it is part of.
For the purpose of point density the mloop colors are simply averaged, which is physically plausible because corners can be viewed
as multiple points in the same location.
When attempting to change a driver variable name to an "invalid" name,
an indicator will now be shown beside the offending variable name.
Clicking on this icon will show a popup which provides more information
about why the variable name cannot be used.
Reasons that it knows about are:
1) Starts with number
2) Has a dot
3) Has a space
4) Starts with or contains a special character
5) Starts with an underscore (Python does allow this, but it's bad practice,
and makes checking security of drivers harder)
6) Is a reserved Python keyword
Thanks to D1080 by @rockets, I've now been able to easily implement the
ability to type multiple word snippets/partial words into the text filter
field (in the Animation Editors), and have it filter the channels which
contain just some of those parts (instead of having to match everything).
For example, the following search strings will now work:
* "loc rot" or "lo ro" will now filter all location and rotation FCurves
* "col loc" will filter all location and color FCurves
* "scale" will also work as before to filter all scale FCurves
But, the following will not work:
* "lc rt" will NOT filter all location and rotation, as the fuzzy search only
breaks down the search string based on whitespace placement
By default, this is not enabled when using name filtering (i.e. magnifying glass is checked,
and some filtering text is specified). Instead, you need to enable the "AZ" toggle beside
the name field. This fuzzy matching is not enabled by default as it could end up being
quite a bit slower on really heavy scenes. (There are probably some optimisation
opportunities, but that's only a future option if someone really needs it)
* 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
The new "default keyframe type" dropdown on the timeline header
(and also the "Keyframe Type" operator/properties in other places)
now has procedurally generated icons which reflect what that keyframe
type will look like when rendered in the Dope Sheet.
This was achieved using the ancient "VICON" (vector icon) stuff
that's lurking around in the dark parts of UI code. From memory,
the only other things that use (or used to use) this stuff included
some of the triangle icons for some dropdown buttons, or something
like that.
Notes:
* Theme colour changes are reflected immediately by these icons.
This is possible because they are all drawn procedurally
* These icons scale with the DPI setting. I manually guessed the size of
these icons. They can be adjusted further if needed.
* I've documented the steps for adding voodoo icons like this on the wiki
(http://wiki.blender.org/index.php/Dev:2.7/Source/Checklists/Vector_Icon)
* It's true that the rendering of these keyframes doesn't quite fit the rest
of the icons in the UI. However, since we're just leveraging the standard
keyframe drawing methods (to avoid discreptancies between the two), we'll
leave it as such for now. Maybe later we can consider blending in a bit of
the glossy keyframe icons in the Icon Sheet?
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 patch adds a new `falloff_type` ('Inverse Coefficients') for Lamps in
Blender-Internal and GLSL.
The current falloff modes use a formula like this inverse-square one:
`I = E × (D^2 / (D^2 + Q × r^2))`
While such a formula is simple for 3D-artists to use, it's algebraically
cumbersome to work with. Game-designers authoring their own shaders
could benefit much more by having direct control of falloff-coefficients:
`I = E × (1.0 / (coefC + coefL × r + coefQ × r^2))`
In this mode, the `distance` parameter is unused (except for 'Sphere'
mode); instead relying on the designer to mathematically-model the
falloff-behavior.
The UI has been patched like so:
