Just using same code for distribution for face/volume as the one
changed/used for vertices since some months.
Note that this change is breacking compatibility, in that distribution
of particles over faces/volume may not be exactly the same as
previously.
Baking rigid body cache was broken if some cached frames already
existed.
This is just a band aid for release, the logic need to be looked into
further.
Previous version was trying to do a quick and simple process in the case
we were only considering smooth/flat status of faces.
Thing is, even then, the algorithm was not actually working in all
possible situations, e.g. two smooth faces having a single vertex in
common, but no common edges, would not have split that vertex, leading
to incorrect shading etc.
So now, tweaked slightly our split normals code to be able to generate
lnor spaces even when autosmooth is disabled, and we always go that way
when splitting faces.
Using smooth fans from clnor spaces is not only the only way to get 100%
correct results, it also makes face split code simpler.
Previously it was returning short, which was really easy to (a) compare against
non-ID type value (b) forget to handle some specific value in switch statement.
Both issues happened in the nearest past, so it's time to tighten some nuts
here.
Most of the change related on silencing strict compiler warning now, but there
is also one tricky aspect: ID_NLA is not in the IDType enum. So there is still
cast to short to handle that switch. If someone has better ideas how to deal
with this please go ahead :)
Issue was nasty hidden one, the dual status (mix of local and linked)
of proxies striking again.
Here, remapping process was considering obdata pointer of proxies as
indirect usage, hence clearing the 'LIB_TAG_EXTERN' of obdata pointer.
That would make savetoblend code not store any 'lib placeholder' for
obdata data-block, which was hence lost on next file read.
Another (probably better) solution here would be to actually consider
obdata of proxies are fully indirect usage, and simply reassign proxies
from their linked object's obdata on file read...
However, that change shall be safer for now, probably good for 2.79 too.
It is possible to have same image used multiple times at different frames,
which means we can not free it's buffers without any guard. From quick tests
this seems to be doing what it is supposed to.
Need more testing and port this to 2.79.
Regression from rBfed853ea78221, calling this inside thread worker was
not really good idea anyway, and we already have all the code we need in
pre-threading init function, was just disabled for vertex particles
before.
To be backported to 2.79.
This patch adds "Pixel Size" to the performance options, which allows to render
in a smaller resolution, which is especially useful for displays with high DPI.

Bug in new ID copying code, thanks once again to stupid nodetrees, we
ended up wrongly remapping MA node->id pointers to NodeTree when copying
materials using node trees...
Enabled cache for frame accessor and tweaked policy so we guarantee keyframed
images to be always in the cache. The logic might fail in some real corner case
(for example, when doing multiple tracks at once on a system where we can not
fit 2 clip frames in cache) but things are much better now for regular use.
Note: this commit seems to work as expected (also with transform
snapping etc.). However, it is rather unsafe - not enough for 2.79 at
least, unless we get much more testing on it. It also depends on three
previous ones.
Note that using a global lock here is far from ideal, we should rather
have a lock per DM, but that will do for now, whole DM thing is doomed
to oblivion anyway in 2.8.
Also, we may need a `DM_DIRTY_LOOPTRIS` dirty flag at some point. Looks
like we can survive without it for now though... Probably because cached
looptris are never copied accross DM's?
This was... horribly wrong, CDDM will often *not* need to allocate
anything to return arrays of mesh items! Just check whether array
pointer is NULL.
Also, remove `DM_get_looptri_array`, that one is useless currently,
`dm->getLoopTriArray` will always return cached array (computing it if
needed).
Bug introduced in recent ID copying refactor.
This commit basically sanitizes seq strip copying behavior, by making
destination scene pointer mandatory (and source one a const one).
Nothing then prevents you from using same pointer as source and
destination!
