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:

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 NEEDS DOCS - both in 2.78 release log and the Blender manual.

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

Image filter was not set, but only if invoked from toolbar (image strip needs to be selected to see the button).
Caused by rB7fa72b8970, Wasn't aware there's another button for this for image strips.
Needed to allow modal UI keymaps, but I'm sure we'll need this more often in future.
First item will be modal eyedropper keymap coming in a following commit.
Now using same UI as in object/armature properties, also save one line in 3DView panesl. ;)
Nothing crucial there, but nice & safe to backport to 2.77 imho.
This is an attempt to improve the User preferences panel for the 3DView. I made 2 changes:
- I reordered the sequence of properties by grouping them into more logical groups as it made sense to me. Please indicate where to rearrange the order if necessary.
- Then i added some changes in the code to get the groups better arranged visually. I am pretty sure that this can be done much better, more clever, more generic, whatever. This is just what i could figure out on my own so far.

The problem is that node trees (such as the Material, Lamp, and Compositor node trees)
are stored as "nested node trees" on the affected datablocks. They are particularly
troublesome to deal with, as the are not easily identified, and also cannot be easily
mapped back to the ID's which actually own them. As a result, the usual automated
methods do not work when dealing with these!
* Remove unnecessary big margins after triangle icons (esp. for keymap items they where waaay to big)
* Remove ugly margin after "Foo (Global)" entries
* Add little margin after expanded key maps
Actually, 3 issues here:
* Keymap items of "Foo (Global)" maps weren't indented enough
* Items after a opened "Foo (Global)" map were indented too much (col was overridden then).
Now take into account `dupli_offset` of groups.
Also fixed another issue related to objects renderability, previous code was giving
bad results due to added temp objects to generate previews (camera, lamp...).
Some dynamic enums, which do not need a valid context pointer, have their 'itemf'
callback always called. This is annoying for introspection tools (like the ones generating
translations, or API documentation), because it means they never have access to all possible
options (enum items).
So now, there is also an `enum_items_static` accessor to get only statically-defined
enum items.
Note: only i18n tools take advantage of this currently, others are still to be updated.

Sculpt settings are often quite handy to be able to easily access while drawing,
so make it easier to access these when drawing without having to first expand
the panel.
(On the other hand, the "Edit Strokes" panel contains tools already found in
various other places - menus,etc. - so no need to expand it by default)
Fixed this with three changes:
* filter_glob is now 255 char max (63 could be a bit limited in some rare cases).
* IO templates now explicitely define max len of that property (such that scripters are aware of the limit).
* ED_fileselect_set_params() is now safe regarding too long strings from a 'filter_glob' op property.
This is handy for cases when mask is created on top of the edit and
used for tasks like color grading and other enhancement.
That was the main purpose of the masks which was totally broken in
6786ef6. Now it's possible to have masks created as both a part of
input movie roto process (which then better be re-mapped to the strip
timing) and as a grading tool (which should be using scene timing
for the animation).
Thanks artists from the Nieve for screaming about such a broken case.
The Vector Transform node is a useful node which is present in the Cycles renderer.

turned off by default for now, and shall be enabled when the library is
present.

This commit adds a "Select Grouped" operator. Although it is set up to
allow more types of "grouping" in future, it current only supports
a single mode (i.e. "Same Layer"). As a result, it does not pop up
any menus/submenus in all the usual places.
