Bug fix #34726

Appending a group (which adds all object members to scene), didn't follow the
setting "In active layer".

One note: only the scene layers are copied over, not local view3d layers.

Node preview merge function now has an additional option "remove_old", which could be used if previous previews should be retained after recalculating (not used currently, old previews are dropped entirely for now, because it could be confusing).

Also moved the sync and merge for previews into the respective tree callbacks for consistency. This way the handling of previews can be changed for each tree type individually if necessary.

Enable previews for inactive compo output and viewer nodes.

This keeps old behavior and could be nice. However, it'll
make compositing slower (doing final compo after editing
tree). This is easy to hide preview in this case, and also
i hope to implement percentage rendering soon.

Fix #34667: trail_count option missing for Particle (emitter) System Render Panel "Path" UI

Patch from Josh Wedlake, many thanks!

Fix #34720: Sculpt mode T panel has no texture preview

Cycles was not able to render texture icons, same actually
goes to lux. Now made it so blender internal is used to render
icons for textures.

Fix #34689: Multilayer EXRs don't load correctly if one layer is named and the other is not

OpenEXR's ChannelList.layers() will not include empty layer names,
which caused the issue. Made it so if there's one non-empty layer
name, check for empty names happens.

If there's empty layer name in case one non-empty layer name, file
will be considered multilayer now.

Attempt to fix windows building with scons

Fix for compositor node preview sizes: Use the render output aspect ratio for estimating the required preview rect size instead of assuming a square, to avoid wasted space. Note that this does not work for newly added nodes until they have first been evaluated and a preview image has been generated (same behavior as before pynodes merge and associated preview changes).

correct enums which were in fact variables defined in headers.

code cleanup: use NULL rather then 0 for pointers, and make vars static where possible.
also found unintentionally defined enum/struct variables that where only meant to be defining the type.

code cleanup: use booleans and const's for operator vars.

fix error with merge operator not handing error cases properly (errors wouldn't cancel the operator as they should).
was mixing up OPERATOR_CANCELLED with 0.

Tweak to previous commit - make range check less strict so that indicators don't
flicker off so easily when target moves off screen

Graph Editor: Draw indicators on the active Driver F-Curve which show the
relationship between the result of driver evaluation (NKEY region stuff) and the
end result applied to the driven properties.

Moved the definitions of Freestyle-specific panels to its own module.
Suggested by Sergey Sharybin through a code review of the branch.

BGE bugfix for [#34505] Vertex Colors not working in the BGE (for custom GLSL shaders) when multitexture and no material

Bug introduced on rev.36723

code cleanup: conversion from blender to BGE was unnecessarily confusing in checking weather to use vertex colors,
move check to function.

scons: fix broken compile since last int -> bool cleanup

Fix for default values different from the factory settings.
Suggested by IRIE Shinsuke through a code review of the branch.

BGE bugfix: [#34550] getVertexArrayLength changed in 2.66

This bug was producing way more geometry than we need. Potentially
memory saver (or performance even) bugfix.

Bottomline is:
We need to initialize the UVs otherwise vertex comparison fails ...
Ideally MoTo should take care of initializing MT_Point2
(note in Windows that seems to be fine, but it's safer to not rely on that)
