Very dummy mistake (someone forgot to increment one of the variables in
one of the loops in that spaghetti nightmare that is nurbs shapekey
code), took half an age to spot it... :/
Conversion code could leave object with inconsistent material data
compared to its new obdata.
Ideally, various conversion code would handle that properly, conserving
materials when possible, but for now at least ensure we get valid
result!
Related to T56363, this is not fixing the root of the bug, but ID
copying should always be a good occasion to ensure sanity of our data
(and error checking is always better than a crash!).
To get consistent, user-expected results here, we need to 'fake'
starting immediately after a 'skip' block (such that we start with a
full block of selected elements).
Same issue affected vertices and edges selection of course, did not
check the other usages of WM_operator_properties_checker_interval_test()
though.
Beautiful example of typo going unoticed and firing back up in totally
unexpected place years later. Guess nobody actually duplicated a Clip
data-block before! :P
Most likely own fault, during refactor of ID copying code.
Patch porting to OpenJPEG 2.3 is by Campbell.
Once all platforms are upgraded we can remove the code for 1.5, and upgrade
or remove the openjpeg version from extern/. This intermediate step makes it
possible for platform maintainers to upgrade to 2.3 without breaking other
platforms.
This make the root flag writable using the Python API, using the
generic skin vertex flag setter function.

Having 'flag, flag2, flag3' is getting out of hand especially
when we support increasing the size of types.
Make flag2 into an int.
Note, this looses the 'show world' option,
but it's not such an important setting.
This is in preparation of upgrading our library dependencies, some of which
need C++11. We already use C++11 in blender2.8 and for Windows and macOS, so
this just affects Linux.
On many distributions this will not require any changes, on some
install_deps.sh will need to be run again to rebuild libraries.
