In this case the Pyobject gets lost from pybm, and bm.free() does not invalidate the PyElem.
This will cause the destructor of python to read invalid memory and crash.
The solution is to make a copy of the pyobjects pointers before overwriting.
This area is a subject of reconsideration, so for now used simplest
way possible -- ensure depsgraph's nodes have proper layer flags
when going in and out of local mode.
That one was:
* Resetting non-ID pointers (lib_link_xxx funcs should only affect ID
pointers, everything else shall be done in direct_link_xxx func).
* Even worse, always calling lib_link_animdata, even when
LIB_TAG_NEED_LINK tag was unset...
We do not need any special handling anymore for usercount of images used
by faces/polygons (tpage stuff), since we have the 'real_user' handling,
which will gracefully cope with all possible situations.
So better not keep that ugly confusing useless special case.
Mainly:
* Add missing `IDP_LibLinkProperty()` calls for many ID types
(harmless currently, but better be consistent here!).
* Bring lib_link_xxx functions more in line with each other.
* Replace some long if/else by switch.
For Windows 8.1 and X11 (Linux, BSD) now use the DPI specified by the operating
system, which previously only worked on macOS. For Windows this is handled per
monitor, for X11 this is based on Xft.dpi or xrandr --dpi. This should result
in appropriate font and button sizes by default in most cases.
The UI has been simplified to a single UI Scale factor relative to the automatic
DPI, instead of two DPI and Virtual Pixel Size settings. There is forward and
backwards compatibility for existing user preferences.

This adds the ability to switch between different application-configurations
without interfering with Blender's normal operation.
This commit doesn't include any templates,
so its mostly to allow collaboration for the Blender 101 project
and other custom configurations.
Application templates can be installed & selected from the file menu.
Other details:
- The `bl_app_template_utils` module handles template activation
(similar to `addon_utils`).
- The `bl_app_override` module is a general module
to assist scripts overriding parts of Blender in reversible way.
See docs:

Ideally we need to find a way to remove such a static limit here, but it's not so
trivial to implement for texture nodes. Requires some bigger system redesign there.
Just raising limit for now, which is fine for modern systems.
