We needed the 'background' feature here, since we never wait on those preview-generation tasks.
Note that it also simplifies the code, and as usual testing is needed here on all possible platforms...
With current code, in single-threaded context, a pool of task may never be executed
until one calls BLI_task_pool_work_and_wait() on it, this is not acceptable for
asynchronous tasks where you never want to actually lock the main thread.
This commits adds an extra thread in single-threaded case, and a new 'type' of pool,
such that one can create real background pools of tasks. See code for details.

In previous code, worker would exit in case it gets awoken from a condition_wait() and
task queue is empty. However, there may be spurious wake up (either due to pthread itself,
or to some race condition between workers) that would lead to wrongly exiting a worker before
we actually exit the whole scheduler. See code for more details.
Metas are scanning all scenes duplis,
which can go into particle systems without an initialized derived-mesh.
For now just do NULL check, its not correct but real fix is not fitting well with current design.
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.
Fix for T46494 wasn't working properly when de-selecting faces,
adjacent faces would remain selected but have unselected edges.
Logic here is admittedly rather fragile since it relies on both
selection functions and flushing afterwards.
Certain shapes could trick the inside/outside test.
An edge between 2 planar faces could be selected for detecting face-flipping (which failed).
While this could be prevented by skipping those edges,
use a method which searches for the outer most face-loop, then check it faces the center.
Works totally similar to backdrop in the compositor.
Requested by Sean Kennedy, but could be useful for lots for VFX guys.

Grabbing now doesn't 'jump' when shift is released (matching rotation modes).
This simplifies most logic for transform input,
where mouse input callbacks can choose to use the 'virtual' cursor,
which accounts for precision when shift is held.
Each time we setted the mass the own object gravity was divided by its
old mass (i.e you could convert you car in a flying DeLorean with a
simple mass car modification).
A note will be included in release notes due to retro compability
issues.
The start position must be initialized at the first call of KX_IpoSGController::Update when m_ipo_start_initialized is to false, not when also the frame time is not 0.
- Add spaces around operators.
- Replace !(a == b) by a != b
- Add "f" at end of float value.
- Remove extras lines in fonctions declaration.
- Remove indentation to align attributes definition.
To make consistent with KX_GameObject.replaceMesh, we don't allow this behavior but print an error message for the replace mesh actuator.
e.g : Warning: object "Cube" from ReplaceMesh actuator "Edit Object" uses a mesh not owned by an object in scene "scene1"

Previously it was possible that same component will be tagged for update
again and again, making update flushing really slow. Now we'll store flag
whether component was fully tagged.
This is still temporary solution because ideally we should just support
partial updates, but that's for the future.
Gives around 10% speedup on file from jpbouza.
This behavior caused a double free.
Before when we duplicated an instance of a group the new instance keep the pointer of the group but was not added in the group instance list (normal).
And during the object deletion we tried to remove the object in the instance list but anyways if it failed decrement the reference count.
Set the group and the instance list to NULL in ProcessReplica avoid these kind of problems.
The reported crash was confirmed as a segmentation fault in std::sort().
The cause of the crash was traced down to a binary comparison function
that was not satisfying the so-called strict weak ordering requirements of
the C++ standard sorting function. Specifically, the comparison operator
has to return false when two objects are equivalent (i.e., comp(a, a) must
be false), but that requirement was not met.
Since the binary comparison operator in question could be a user-defined
Python function, here a safety measure is implemented in the C++ layer to
make sure the aforementioned requirement is always satisfied.
Bug introduced in 583fa7d1e, KX_GameObject.setActionFrame can make BL_Action::m_starttime negative. But in BL_Action::Update m_starttime is set to the current time if it's negative.
To fix it we use a boolean BL_Action::m_initializedTime to know if we should initialize the time in BL_Action::Update, it's more stable than comparing times.
Tested with bug task T45945 and T32054, with an extra patch about to fix suspend resume scene issues with actions : D1569
Shutter curve now can be controlled using curve mapping widget in the motion
blur panel in Render buttons. Only mapping from 0..1 by x axis are allowed,
Y values will be normalized to fill in 0..1 space as well automatically.
Y values of 0 means fully closed shutter, Y values of 1 means fully opened
shutter.
Default mapping is set to old behavior when shutter opens and closes instantly.
This shutter mapping curve could easily be used by any other render engine by
accessing scene.render.motion_blur_shutter_curve.

Previously curve mapping was always setting to only a single slope which then
was symmetrizied by a tools (such as brush or compositing).
With this change it's possible to set curve to symmetrical slopes as a part
of preset.
