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:

World space and view space normals were mixed up, we should only convert from
world to view space if a custom normal is connected, otherwise it is already in
view space.
The issue was introduced by a fix for T44713 which only made GLSL
consistent with Cycles.
Now we do have conditional averaging or proper luma weighting based
on whether we're new old old shading system. Not totally ideal but
should work for until we re-design viewport possibly breaking how
Blender Internal does implicit conversion.
This patch supports "Image or Movie" and "Environment map" types of world texture for the viewport.
It supports:
- "View", "AngMap" and "Equirectangular" types of mapping.
- Different types of texture blending (according to BI world render).
- Same color blending as when it lacked textures (but render via glsl).

Wireframe drawing doesn’t use the following GL state, so don’t update
these:
- ShadeModel
- NormalPointer
- ColorPointer
Normal & color data are still uploaded as part of the interleaved VBO,
but those attributes are disabled for wireframe.
This patch adds a new API which allow us to access light shadow settings from python. The new API can be used to write custom GLSL materials with shadows.

I put all usage of GL_POINTS under the microscope. Fixed problems &
optimized a couple of spots.
- reduce calls to glPointSize by about 50%
- draw selected & unselected vertices together for UV editor & EditMesh
- draw initial gpencil stroke point the proper size
- a few other smaller fixes
New policy: each GL_POINTS draw call needs to set its desired point
size. This eliminates half our calls to glPointSize (setting it back to
its 1.0 default after every draw).
Beside the obvious ARB -> GLSL change, the texture slicing algorithm had
to be rewritten.
Although this new algorithm has the same behaviour as the old one (view
aligned slicing), it works with an arbitrary number of slices (which
could eventually be set by the user), which means we can preallocate the
buffer. The previous algorithm would slice from the begining to the end
of the volume's bbox, and draw the slices as it generates them.
Also support for ARB program was removed.
Patch by myself, with some minor fixes by Brecht.

This commit changes the way how we pass bounce information to the Light
Path node. Instead of manualy copying the bounces into ShaderData, we now
directly pass PathState. This reduces the arguments that we need to pass
around and also makes it easier to extend the feature.
This commit also exposes the Transmission Bounce Depth to the Light Path
node. It works similar to the Transparent Depth Output: Replace a
Transmission lightpath after X bounces with another shader, e.g a Diffuse
one. This can be used to avoid black surfaces, due to low amount of max
bounces.
Reviewed by Sergey and Brecht, thanks for some hlp with this.
I tested compilation and usage on CPU (SVM and OSL), CUDA, OpenCL Split
and Mega kernel. Hopefully this covers all devices. :)
While SCons building system was serving us really good for ages it's no longer
having much attention by the developers and started to become quite a difficult
task to maintain.
What's even worse -- there started to be quite serious divergence between SCons
and CMake which was only accumulating over the releases now. The fact that none
of the active developers are really using SCons and that our main studio is also
using CMake spotting bugs in the SCons builds became quite a difficult task and
we aren't always spotting them in time.
Meanwhile CMake became really mature building system which is available on every
platform we support and arguably it's also easier and more robust to use.
This commit includes:
- Removal of actual SCons building system
- Removal of SCons git submodule
- Removal of documentation which is stored in the sources and covers SCons
- Tweaks to the buildbot master to stop using SCons submodule
(this change requires deploying to the server)
- Tweaks to the install dependencies script to skip installing or mentioning
SCons building system
- Tweaks to various helper scripts to avoid mention of SCons folders/files
as well

nVidia Linux driver reports GL_CONTEXT_PROFILE_MASK = 0, which is a bug.
In that case check for the ARB_compatibility extension.
Non-buggy drivers will continue to use
GL_CONTEXT_COMPATIBILITY_PROFILE_BIT.
Thx to Dr Hackerman for reporting.
Only used for color for now, but we need this for any kind of buffer
updates actually.
This should get rid of some allocation/deallocation, making
vertex painting a bit faster.
The is intended to replace the deprecated glPolygonStipple() calls with a shader
based alternative, once we switch over to GLSL shaders.

FBOs are a GL 3.0 feature but enjoy nearly universal support via
extensions.
The newer ARB extension brings these features to GL 2.1 without needing
an ARB suffix.
The older EXT extensions *do* use a suffix. Since we don’t know which
is used until runtime, I added the suffix to all functions & enums.
Also updated the check to look for the FBO feature set instead of the
specific EXT extension.
Maybe this is pedantic but I read it’s best to explicitly set the
desired component size.
Also append “_ARB” to float texture formats since those need an
extension in GL 2.1.
