In some instances, the number of control vertices of a hair could change mid-frame.
Cycles would then be unable to calculate proper motion blur for those hairs. This adds
interpolated CVs to fill in for the missing data. While this will not necessarily result in
a fully accurate reconstruction of the guide hair, it preserves motion blur instead of disabling it.

This causes a feedback loop in 2.8x,
where gizmo redo caused fake mousemove that executed gizmo again.
Move the mousemove into the undo/redo operator.

That bug probably did not affect 2.7x, only 2.8 with COW copying IDs in
threads... But root of the issue is that underlying boost i18n lib does
not support well multi-threaded access. So simply forbid any translation
from non-main thread. This *may* be an annoying limit at some point, but
doubt it will be any issue currently.

Getting the instance leaks memory and was only meant to be used for
generating docs.

Replace direct access using PyThreadState_GET

That pointer can be NULL, RNA default string handling does not support
that. (that whole uv_layer prop is quite nasty actually, since it does
not own that string, always borrows it from some other data :((( ).

Just pass as an argument.

* WITH_SYSTEM_OPENJPEG is removed and is now always on, this was already
the case for macOS and Windows.
* This should not break existing Linx builds. If there is no new enough
OpenJPEG installed, CMake will no find libopenjp2 and WITH_IMAGE_OPENJPEG
will be disabled.
* install_deps.sh was updated with new package names, since distributions
put this version in a new package.

Was using UI_BLOCK_LOOP to control draw style,
this meant we couldn't use popup theme colors for cases
where it the interface has the same purpose as a popup but happens
not to use this flag.

When using the 'normal' orientation, the normal would be ignored
if the plane couldn't be calculated.
Now use only the normal if the plane is zero length,
this was already done, just not in all cases.

In a real world it is very weird to disable AA on a mask,
it will give ugly looking result. For some fast preview
passes (like in the node preview) the system can decide
to disable AA without asking user to do anything.
One thing we can consider doing is to remove Feather
option as well. If real compo becomes measurably slower
in cases when mask has no real feather, we can disable
feather internally, without user input. Disabling
feather in the interface is like making things faster
but giving a wrong result, which doesn't sound that
helpful either.

The issue there was that number of layers did not include normals,
while element size counts bytes used by normals. This sounds very
fragile and dangerous to work further. Also, one value can easily
be delivered from another, so it is redundancy going on here.
Possible difference now is that multires subdivision will copy
normals to a higher levels. Shouldn't be big of a problem, since
leaving old normals and updating coordinates is not correct either.

Not freeing its BVHTree in case there were no collision objects,

MASS unit was already implemented for the C api. Only making sure it is
accessible in the python api. Also added 'CAMERA' to the documentation as a valid option.

The statement that PBVH needs to keep track of CCGDM is wrong, PBVH itself
does not care about CCGDM at all, and it's weird for it to carry on this
beast so others can access.
Even more, nobody will actually caring about CCGDM itself, all the usages
were checking whether there is CCGDM or not. This is as good as simply
checking PBVH type.
Tested with an original report T53551 and everything is still stable.

While the crash is in 2.8, it's possible undo operates on data
which isn't only owned by the current scene (any object for eg).
Thanks to @mont29 for suggesting the fix.

This changes the text hinting setting to be an enum with options
Auto / None / Slight / Full. The default is Auto which currently disables
hinting.
The hinting was tested with a new FreeType version, but this is not what
is used on the buildbots an official release environment, and the fonts
look quite bad because of that. Once FreeType has been upgraded we can
change the default.
Even then the results are not ideal, perhaps due to missing subpixel
positioning and linear color blending support in BLF.
