Idea is to replace hard-to-track (id->lib != NULL) 'is linked datablock' check everywhere in Blender
by a macro doing the same thing. This will allow to easily spot those checks in future, and more importantly,
to easily change it (see work done in asset-engine branch).
Note: did not touch to readfile.c, since there most of the time 'id->lib' check actually concerns the pointer,
and not a check whether ID is linked or not. Will have a closer look at it later.

This commit changes a lot of how IDs are handled internally, especially the unlinking/freeing
processes. So far, this was very fuzy, to summarize cleanly deleting or replacing a datablock
was pretty much impossible, except for a few special cases.
Also, unlinking was handled by each datatype, in a rather messy and prone-to-errors way (quite
a few ID usages were missed or wrongly handled that way).
One of the main goal of id-remap branch was to cleanup this, and fatorize ID links handling
by using library_query utils to allow generic handling of those, which is now the case
(now, generic ID links handling is only "knwon" from readfile.c and library_query.c).
This commit also adds backends to allow live replacement and deletion of datablocks in Blender
(so-called 'remapping' process, where we replace all usages of a given ID pointer by a new one,
or NULL one in case of unlinking).
This will allow nice new features, like ability to easily reload or relocate libraries, real immediate
deletion of datablocks in blender, replacement of one datablock by another, etc.
Some of those are for next commits.
A word of warning: this commit is highly risky, because it affects potentially a lot in Blender core.
Though it was tested rather deeply, being totally impossible to check all possible ID usage cases,
it's likely there are some remaining issues and bugs in new code... Please report them! ;)

The issue was caused by some code accessing R from a functions which
are marked as safe for use from outside of render pipeline.
Now those functions are safe(er) for use.
We have callbacks for that, they also do some checks and help ensure things are done
correctly. Only place where this is assumed not true is blenloader (since here we
may affect refcount of library IDs as well...).
Brush.toggle_brush was allowed to be an invalid pointer,
it worked for the one operator that used it - but in general bad practice,
requiring a lookup on every access.
Ensure the pointer is kept valid now.
Idea is, instead of ignoring completely missing linked datablocks, to
create void placeholders for them.
That way, you can work on your file, save it, and find again your missing data once
lib becomes available again. Or you can edit missing lib's path (in Outliner),
save and reload the file, and you are done.
Also, Outliner now shows broken libraries (and placeholders) with a 'broken lib' icon.
Future plans are also to be able to relocate missing libs and reload them at runtime.
Code notes:
- Placeholder ID is just a regular datablock of same type as expected linked one,
with 'default' data, and a LIB_MISSING bitflag set.
- To allow creation of such datablocks, creation of datablocks in BKE was split in two step:
+ Allocation of memory itself.
+ Setting of all internal data to default values.

painting.
Also system added a brush every time it found no paint brush in the
system which is not what we would want.
Solution:
* Brush panel stays visible always, regardless of whether there is a
brush or not.
* We search for first available brush when we find no brush in paint
struct instead of always generating a new one.
* Generating and searching for a brush take a mode argument now. Needed
some refactoring to users of BKE_paint_init as well.
* Did some style cleanups for paint mode enums.
Patch is big but it's mostly argument refactoring.
Deprecate wrap (BRUSH_TORUS) option, we now have paint flags for tiling
and we can reuse those. Also allows seperate tiling in X/Y
direction for 2D painting now.
Only one tiling is allowed for now.
Options can be found in new "Tiling" panel under the tools tab.
For version patching, we just turn off brush wrapping,
to allow reuse of the flag in the future.
New option is paint mode wide instead of per brush so
a brush having the old wrap option will not enable it
for the whole mode in the version patch.
Was doing clamping as fix for T42984. Seems we can ommit clamping for
sculpting if we make sure overlap is not zero with negative values.
Control for clamping is moved to the "Use Clipping" function of curves
(which is on by default), so both bugs remain squashed and advanced
users can now properly utilize curves in sculpting, though not all
brushes work well with negative curves.
The issue was caused by the conflict between preview render which would set
R_NO_IMAGE_LOAD flag on the renderer and texture samplers called outside of
the render pipeline trying to use this flag.
Now the sampler functions accepts extra argument so render pipeline can
still skip image load, but calls outside of the pipeline will nicely load
all the images.
Not cleanest change in the world but good enough to unlock gooseberry team,
and assuming we already had pool passed all over the place it should be all
fine.
Will need to reshuffle arguments into SamplerOptions structure later.
Propper fix reverting most of rB60e70c0c6014e5, which was only partial specific fix.
This code uses generic `BKE_id_lib_local_paths()` func to handle all possible paths.

curves.
Issue here is that brush curve could return negative values. This would
result in overflow of mask values. Those were not visible during real
time preview because result would be clamped.
We had two functions in the code, one of which allowed negatives but I
don't think that we really want that, users have no control over the
negative values at all anyway.
Thanks to the reporter, Leon Cheung for figuring out the issue :)
This commit includes a few things:
* It moves the Rake and Random flags from the brush to the MTex.
* The first change allows mask textures to have independent rake
support.
* Random rotation now has an angle value that controls the width of the
effect from the rake or default angle
* Rake and Random are now supported together.
Yep, at last it's here!
There are a few minor issues remaining but development can go on in
master after discussion at blender institute.

Thanks to Sergey and Campbell for the extensive review and to the
countless artists that have given their input and reported issues during
development.
Previously this only worked for some datablocks relevant to rendering, now it
can be used to detect if any type of datablock was added or removed (but not
yet to detect if it was modified, we need many more depsgraph tags for that).
Most of the changes are some function parameter changes, the important parts
are the DAG_id_type_tag calls.

* Move symmetry options to the paint struct (where all paint systems can
make use of it)
* Rename draw_pressure to stroke_active. This is what is really checked
on those occasions that this is used. Also move turning on/off of this
option to the stroke level and avoid doing it on every stroke system.
* Rename BRUSH_RESTORE_MESH to BRUSH_DRAG_DOT. In image painting this
won't restore any mesh, so better have a name that is directly linked to
what the flag actually does.
Summary:
Seems to be known TODO in the code, but no idea why it
was never solved, especially since tweak is so much easy.
It might be arguable that we need to support painting
color space, but it's still much better to convert to
sRGB space. It's gonna to cover 90% of cases anyway.

attenuation that should really be optional. There's also a minor
performance penalty and all this only for one problematic case. In case
the tool flattens two surfaces, users can manually set the front face
only option. A better non-attenuating way to cull such vertices can be
added later.
Also flatten brush should calculate the flatten plane from the original
vertices or the flattening will not converge for planes offsets
different than zero.
Reported by Michalis Zissiou, thanks!
* Cleanup for previous commit and reduce some local variable referencing
* Add support for brushes that operate on frontfaces only and do not
show the option for those brushes. Currently only clay strips is in the
list but this may change according to artist feedback. This should take
care of the "sticky" surface problem completely.
rotation of the brush mask texture.
Unfortunately secondary path does not work here because we do not have a
permanent switch to choose between primary-secondary brush texture. Use
operator property instead.
initialization. In sculpt mode, when using shift-click to switch to the
smooth brush it was possible to ommit initialization of curvemapping for
that brush.
This was in fact really nasty bug, caused by multitex_nodes
function using global variable R (which is a copy of current
renderer). this variable is not initialized to anything
meaningful for until first rendering (preview or final)
happened.
Since multitex_nodes might be used outside of render pipeline,
made it so whether CM is on or off as an argument to functions
multitex_ext_safe and multitex_ext. Now multitex_nodes() is
only shall be used for stuff happening from render pipeline!
Also needed to make some changes to other places, so all the
usages of texture sampling knows for the fact whether CM is
on or off.
And one more change is related on behavior of dispalcement,
wave, warp, weightvg modifiers and smoke. They'll be always
using CM off since texture is used for influence, not for
color.
It's rather bigger patch, but it's mostly straightforward
changes, which we really need to be done.

Also did some refactoring of this code, moving the brush image creation code
out of brush.c and making it consistent with image updating code.
