The goal is to prevent assignment of temporary or evaluated meshes
to objects from the main database.
Majority of the change is actually related on passing reports around.
On a positive side there are more error prints which can become more
visible to scripters.
There are still possible further improvements in the related areas.
For example, disable user counting for evaluated ID datablocks when
assignment happens. But can also happen later on as a separate
improvement.

This follows the 3D view, adding an "Options" tab.

Note that the same issue actually showed without a frame node, when
trying to click-drag on a socket on its 'inside node' part, you would get
same behavior.
Only solution I can see here is to prevent Node selection to go on when
user clicks on one of its sockets, there is no way afaik to make
drag-from-socket to start if we keep select-node operator running
modal, since both operators (NODE_OT_select and NODE_OT_link) use the
same shortcut, if select (which is checked first, being a Tool) returns
modal, then event is considered handled it seems, even though
Passthrough is also returned...

Left-click select broke that behavior, since it puts both action and
select buttons on the same physical mouse button...
To support this behavior again, we have to split selection process in
two steps, hence make it modal... While I remain rather skeptical about
that global design decision, and complexity it adds to many UI/UX areas,
this solution ends up being OK-ish I think.
Thanks to @brecht for some final tweaks on the patch.

Cycles lights now use strength and color properties of the light outside
of the shading nodes, just like Eevee. The shading nodes then act as a
multiplier on this, and become optional unless textures, fallof or other
effects are desired.
Backwards compatibility is not exact, as we can't be sure which renderer
the .blend was designed for or even if it was designed for a single one.
If the render engine in the active scene is set to Cycles, lights are
converted to ensure overall light strength remains the same, and removing
unnecessary shader node setups that only included a single emission node.
If the engine is set to Eevee, we increase strength to remove the automatic
100x multiplier that was there to match Cycles.

Cycles now uses the color space on the image datablock, and uses OpenColorIO
to convert to scene linear as needed. Byte images do not take extra memory,
they are compressed in scene linear + sRGB transfer function which in common
cases is a no-op.
Eevee and workbench were changed to work similar. Float images are stored as
scene linear. Byte images are compressed as scene linear + sRGB and stored in
a GL_SRGB8_ALPHA8 texture. From the GLSL shader side this means they are read
as scene linear, simplifying the code and taking advantage of hardware support.
Further, OpenGL image textures are now all stored with premultiplied alpha.
Eevee texture sampling looks a little different now because interpolation
happens premultiplied and in scene linear space.
Overlays and grease pencil work in sRGB space so those now have an extra
conversion to sRGB after reading from image textures. This is not particularly
elegant but as long as engines use different conventions, one or the other
needs to do conversion.
This change breaks compatibility for cases where multiple image texture nodes
were using the same image with different color space node settings. However it
gives more predictable behavior for baking and texture painting if save, load
and image editing operations have a single color space to handle.

Refactor a bit node selection code, mostly in the socket selection in
one place 'extend' logic usage was inverted, deselection of other
sockets/nodes was not working properly.
Also now make node active when selecting a socket, this makes more sense
and makes the NODE_OT_link_viewer macro much more useful (this is the
only user of the 'socket select' feature currently, afaics).

This is a continuation of rB7fdffd735ff24, where I separated the
e.g. frame number drawing from scrollers internally.
This patch changes the API, so that space draw handlers
have to draw these numbers explicitely.
This greatly simplifies the scrollers API for all spaces
that just need scrollers without any frame numbers.

Forgot to do that for some in previous commits, that kind of props are
better with 'skip save' behavior (simpler to handle in keyconfigs).

Previously only a fixed bounding box could be used.
This was not flexible enough.
T63193 will benefit from this refactor.

On file read we need to update group nodes in case the group they refer to
has changed its inputs and outputs. This had O(n^2) time complexity and was
updating all datablocks even if they did not change.

Each space had separate operators, duplicating logic.
Use RNA properties instead so adding the ability to toggle other
region types (floating redo region for eg) doesn't need to have an
extra operator per space type.
It's also nicer to show a check-box for something which can be toggled.

No functional change, this adds LIB definition and args to cmake files.
Without this it's difficult to migrate away from 'BLENDER_SORTED_LIBS'
since there are many platforms/configurations that could break when
changing linking order.
Manually add and enable WITHOUT_SORTED_LIBS to try building
without sorted libs (currently fails since all variables are empty).
This check will eventually be removed.

Now the entire node gets greyed out, instead of using a red header that is

Request from the Spring team. When compositing the CTRL-Shift Click on a
node cycles the viewnode with an output socket. When you have many
render layers you spend time cycling to the desired socket. This patch
allows the user to CTRL-Shift Click on a socket to connect directly to
that socket.

This was already supported for Cycles shader nodes, but now also works for
Eevee and compositing nodes. Instead of a generic NodeCustomGroup, now
there is ShaderNodeCustomGroup and CompositorNodeCustomGroup that can be

Convention was not to but after discussion on 918941483f7e we agree its
best to change the convention.
Names now mostly follow RNA.
Some exceptions:
- Use 'nodetrees' instead of 'nodegroups'
since the struct is called NodeTree.
- Use 'gpencils' instead of 'grease_pencil'
since 'gpencil' is a common abbreviation in the C code.
Other exceptions:
- Leave 'wm' as it's a list of one.
- Leave 'ipo' as is for versioning.
