It was possible race condition on empty curves -- it's possible that curve
object is fully updated and path is null in that cases, Proper way to deal
with this is to check curve_cache for non-NULL.
It was kept disabled due to render artifacts which weer in fact caused by bad
memory access, which is fixed in the previous commit.
We now also can make it enabled in regular AMD split kernel after someone tests
the updated code.
This is needed when you want to bake only part of an armature's bones, since they
all share a single action, otherwise you'd lose non-baked bones' animation...
This will print a warning and users will get overlap of pie buttons, but
it should be quick paper over the cracks and at least should keep
blender working until a more complete fix is coded.
Tweak event was being added to the end of the event queue (out of order),
meaning any mouse releases already in the queue wouldn't be used to exit the gesture.
Gestures could get stuck (mostly when the system wasn't able to handle events fast enough).
Now tweak events are now added in order.
This will fix exporting of metadata and importing for imbufs, but image
editor will not display these metadata since multilayer gets converted
to renderresult, which does not support metadata display yet.
This commit is more meant for external image editors/viewers.
Use first packed image as legacy image->packedfile, so saving .blend file with
latest builds makes it so packed images are not lost when opening with previous
releases.
This will only work reliably if mutliview is not used, otherwise it'll be only
first view in the .blend file, which is rather expected since previous releases
are not aware of views.
Enum's itemf callback can be called without context in some cases (UI, doc generation...).
Python's enum properties did not handle this at all - it's kind of odd this did not cause
more trouble and wasn't notice earlier... Probably dynamic enums using context are not
much used in py code.
Note about nodes: those are heavy users of dynamic enum with context. Now,
we expect `NodeCategory.poll()` and `NodeItem.poll()` to always be called with
a valid context (since when there is no context available, we can assume `poll()`
is always True). `NodeCategory.items()`, however, must accept NULL context, so if
you use custom `items` callable for your custom node categories, you may need
to update it (as was done here for builtin `node_group_items()`).
The code was failing to compile on runtime because of some path differences,
and it seems we don't need to specify full path to the file which originally
seemed to be needed to make include directives expansion working correct.
This was broken after the kernel file restructure.
Variables allocated in the __local address space can only be defined
inside a __kernel function.
We probably need to solve this a bit differently once we do the CUDA
kernel split, but this fix shoud be good enough until then.
