Many users have been requesting a way to remove unused datablocks from the file/session
"without closing and reopening" Blender (or at least that's the impression I'm getting).
This commit adds a new operator (exposed as the "Purge All" button in the header of
the "Orphaned Datablocks" mode in the Outliner, which seems to be the logical
place for this) for doing so. It does so by wrapping up the save and "revert"
(i.e. reload the saved file from disk, without needing to quit Blender) operators
along with a confirmation prompt for good measure.
Caveats:
* Ultimately, we still cannot really cleanly delete any datablocks from the current
session outright without reloading the file/data at some point. Thus, we do need
to reload the file again before it can be used.
* This does mean that this operation is irreversible. Notably, Undo history is lost
is doing this operation. Hence the warnings... (Then again, undo/redo actually
reloads the entire scene DB from memory, so it's not anything uncommon ;)
Other Notes:
* The addition of this operator brings this mode more into line with being a kind of
"Trashcan" place, with this new operator being the manual "Empty Trash" button.
If the "Orphaned Datablocks" name is too obscure, maybe we could rename this
mode to "Trash" or something similar?
When in "Orphaned Datablocks" mode, the restriction columns are used to display
usercount indicators and toggles to manage whether datablocks get saved or not.
* The first column shows an icon to indicate whether that datablock is going to get
saved. A tick indicates the datablock will be saved, while a cross indicates the
opposite. Clicking on this changes whether the datablock will get saved.
* The second column shows the usercount.
* The third column shows whether the datablock has a fake user.
Notes:
* The second and third columns are pretty much redundant (functionally speaking).
While it is possible to also toggle fake users by clicking in the third column,
its role here is more as information for power users (and hopefully to allow others
to connect the relationship between the saved/not saved status and fake users)
* I'm not sure whether the use of the X here for the "not saved" state stands out enough
to draw user's attention to items which are "in the danger zone".
Orphaned datablocks are those which have either:
* 0 users
* A "fake" user only
In the case of the former, they will be quietly discarded from the file on the next
save + reload. Hence, it is helpful to have a view where you can confirm which ones
fall into this category and might be worth saving.
We also include datablocks with a fake user only so that datablocks given a user
above can have that easily turned off again (in case the user makes a mistake).
Another benefit of showing these is that it become easier to remove fake users from
datablocks you no longer want retained without having to hunt for them.
Turned out that I misinterpreted the feature request, plus there are some
minor issues with the commit that would need to be corrected.
After all, I decided to just remove it again as it seems to not be really
useful for the users.
- all mathutils types
- only works on frozen data (so vectors can be used in sets/dict keys)
- uses same method as CPython, (matches hashing a tuple)

Due to changes in the way animation updates were handled,
BL_ArmatureObjects were no longer registering to KX_Scene as animated.
Moguri says: It might have been relying on the deformer update which
moved rom being called on every object in the render step. Now
armature deformers are only updated if they need to be.
Fix T42919 & Fix T42218
This reverts the change made in 8872cba7e9
which was contributing to actions being lost in some cases [1], even when
they were assigned to those actuaters, which needed them to be able to
function. Now there's one less case where users are needed but were missing :)
Note that this still doesn't solve the core issue where nothing is responsible
for associating actions created for a particular datablock (and not currently
being used in its active action slot, or in the NLA stack) with that datablock.
That issue is the cause of most action disappearances as well as for other problems
(such as renaming bones being unable to fix unreferenced/unused actions) where there
are diifferences between users' mental models and the data model. Proper fixes are
coming soon (restoring fake users here isn't a proper fix, as it only masks the
fundamental mismatch/problem here).

This way both BLI_assert() and abort() called directly shouldn't
leave any files in the temp folder.
Previously it was really possible to have gadzillions of files
left over because of assert failures and debug aborts during the
development process.
Draw the grid last with depth masking disabled. That should have no ill
effects otherwise as far as I can tell except from some exceptional
cases (axis lines over grid) but this is hardly annoying.
Generally to properly solve such issues we need to have a better render
pipeline with wire objects/materials being drawn after compositing. This
is not impossible but for now doing it the simple way.
Originally the files are coming from ancient early-2.4x epoch, but in
theory such setups might have been re-saved multiple times already with
more recent blender versions.
So the verisoning code is applied on all the files, including very
recent ones.
Bumped subversion, because this check si not really cheap.
We make sure that good values are passed to GetPolygon() and we check that the visual mesh doesn't have a wrong displacement when it passes over a object which has a mesh triangle as compound bound.

This commit introduces a few ready made effects for the 3D viewport
and OpenGL rendering.
Included effects are Depth of Field, accessible from camera view
and screen space ambient occlusion. Those effects can be turned on and
tweaked from the shading panel in the 3D viewport.
Off screen rendering will use the settings of the current camera.

This was rather annoying, since if you were script-editing a .blend file in background
mode, opened through this commandline option system, and wanted to save over,
a mere `bpy.ops.wm.save_mainfile()` *would not* overwrite expected file,
but instead write/replace the dummy `untitled.blend` one!
This feature has been totally broken for a long time. It was added
originally because negative frames were not supported.
Giving simulations (cloth and others) time to settle before animation
starts needs to be solved in a much better and more generic way.
