move only the origin and not the bone. It doesn't need to use any object
matrices to add the bone, the only reason this worked before is because they
were still unit matrices due to depsgraph not running immediately on add.
with other applications launching SDL applications from Blender.
At the time this was added the game engine joystick code was unnecessarily
initializing the SDL video subsystem, and looking at the SDL source code that's
the only place this environment variable is read. That doesn't happen anymore,
though we do have WITH_GHOST_SDL now. But the environment variable is set after
GHOST has been initialized, otherwise this code would have actually broken that.
This is not the nicest behaviour but trying to keep both bullet and
blender side objects in sync breaks in this case.
There might be a better soluion but this avoids crashes for now.
Fixes: [#35995] Delete crash on specific scene (Physics)
the report explains the issue in detail, but basically you couldn't know if a mesh was in editmode without checking all the objects that use it.
add `is_editmode` readonly property for all datatypes which support editmode.
also make rna fail to build on implicit function declarations.
- poll function now checks for a mesh.
- other selected lattices would crash, check for meshes there too.
- better reporting when transfer fails.
- remove feature to sync with active bone after transfer, other tools don't do this (we could make into a generic function if its needed).
tweakmode, this will now result in tweakmode being exited instead of going into
a weird limbo-land where channel selection has changed (but tweakmode is still
active but not drawn)
Selection state of F-Curves is lost when resizing the Graph Editor.
The problem was that SIPO_TEMP_NEEDCHANSYNC was getting set in the graph_init()
callback, which gets called everytime the view resizes, and not just the very
first time this happens. However, setting this flag forces the selection state
to the updated/pulled from the scene data.
In the past, it was necessary to set this flag so that we could force F-Curve
colors to get initialised correctly. However, things probably changed at some
point, so this behaviour is no longer needed. At worst now, opening a new graph
editor may not show F-Curve selection correctly synced with the viewport, though
that's easily worked around by reselecting whatever it is in the 3d view.
