After looking into this more carefully, I've found that we do in fact need a dedicate
operator to add some custom logic when trying to unlink an action from the editor/datablocks.
Specifically, this new operator does the following:
1) When in Tweak Mode, it shouldn't be possible to unlink the active action,
or else, everything turns to custard.
2) If the Action doesn't have any other users, the user should at least get
a warning that it is going to get lost.
3) We need a convenient way to exit Tweak Mode from the Action Editor
4) If none of the above apply, we can just unlink normally
This commit implements this for the Action Editor, with stubs for the NLA Editor too.
Those will be fixed next.

Short description:
With this we can distinguish between holding and tabbing a key. Useful
is this if we want to assign to operators to a single shortcut. If two
operators are assigned to one shortcut, we call this a sticky key.
More info is accessible through the design task and the diff.

A big "Thank You" for you all!
Only basic fix, the whole 'dir' field handling needs rework to correctly support
lib stuff (will be done as part of asset-experiment rewriting work)...
All this code is doing way too much filesystem inspection by itself, instead of
reusing flielist.c work - this is stupid, and will completely break with future
asset engines!
We now have a specific flag for that, use it! Note that for all 'search menu' buttons,
there is already a similar behavior, so there is no need to force apply butt in this case
anyway, which means in practice this change only has effect in the single place
it is needed currently - file browser dir/file fields.
In this case (dir field), applying button even on partial matches leads code
to ask to create a new dir, which breaks completely the expected behavior of
completion. And we do not need immediate apply at all here.
Note this is the only 'autocomplete' button not using search menu, so this change
does not affect anything else in UI.
When renaming animation channels, the old names are no longer drawn behind the
text boxes anymore. This used to cause problems if the names were long, or
if text boxes were set to have transparent backgrounds.
Thanks to kopias for reporting on IRC.
Made all action management operators use the AnimData-local flag instead of the scene
global one. Technically, this is more accurate and results in less blocking
situations (i.e. another object may be in tweakmode, but because of that, the active
object's action couldn't be stashed).
The main impetus for this though was that the Action Up/Down feature doesn't clear
the global flag, since it is not in a position to do so (since it can't load up
everything to clear it).
TODO:
I'll need to review how this global flag works and/or potentially ditch it (or
perhaps add some better ways to ensure that it stays valid), since while thinking
this over, I've noticed a few problems here. But, for the meantime, this commit
at least makes things more usable here in the short term.
Now marking NLA Tracks as Solo'd and muting the NLA stack are linked together
when using the Action Layer Up/Down tools. That is, when switching from a NLA strip
to the active action, if the track was solo'd, then the NLA stack will get muted;
and when switching from the active action to a NLA track, if the stack was muted,
the track will get solo'd. This linkage means that we ensure that when moving up
and down the stack, we can continue to check the actions in isolation without things
messing up when you switch to and from the active action.
Also fixed a bug where this wasn't getting applied when going in the other direction.
TODO:
- When we get the rest/reference track support, we're going to need to insert
some calls to flush the restpose values so that values from the previously
used action do not pollute the pose for the new action (if not all the
same controls get keyed across both). For now, it's best to only do this
switching from the first frame.
With this feature, it is now possible to quickly switch between different actions
stacked/stashed on top of each other in the NLA Stack without having to go to the
NLA Editor and doing a tab-select-tab dance, thus saving quite a few clicks. It
was specifically designed with Game Animation / Action Library workflows in mind,
but also helps layered animation workflows.
Usage:
Simply click on the up/down arrow buttons (between the action datablock selector
and the pushdown/stash buttons) to go to the action in the NLA Track above/below
the NLA Strip being whose action is being tweaked in the Action Editor.
Notes:
- These still work when you're not editing the action used by a NLA Strip.
If you're just animating a new action normally, it is possible to use the "down arrow"
to temporarily jump down to the previous action without losing the new action you're
working on, and then use the "up arrow" to get back to it once you're done checking
the other action(s).
- If there are multiple actions/strips on the same layer/track, then only the one
closest to the current frame will be used.
Added translation there, also fixed a stupid bug which was leading most internal
operators to have 'dual' i18n_context (default NULL one and default 'Operator' one).
Halo is not possible when using 'deep' buffer shadow - reflect that in UI.
When not using buffered shadows, switch lamp bufftype to 'regular' on render, as already
done with 'halfway' method.
A nice bug combining all the broken features of blender:
Particles, duplis and multiple scene dependencies.
Fortunately this was solvable: Basically, we need to
make sure derivedmesh for dupli instance is generated before
obmat is overriden. This also makes sense, since no instance
has "true" obmat apart from original. Lazy initialization of
derivedmesh just does not work here (or it -does- work but first
use should be before instance drawing).
Fingers crossed nothing else breaks after this...
sequencer.
Missing snap callback case. Quick patch is to use the sequencer specific
operator instead of generic translate. We really need to support proper
snap/snap options at some point though.
The function to get a list of markers was not clearing the list before it exited
early, and with no way to tell that the method failed, callers could make the
mistake of trusting that the list was now valid (i.e. either full of marker
frames or empty, vs being invalid)
From the various forum threads and the fact that a new addon has cropped up,
it appears that it is not that well known that this tool exists, and that it
can be used solve a very common problem that animators face. Namely:
When you've gone through blocking out your key poses and then realise
that you need to adjust parts of the rig which don't change much, this
tool solves the problem of needing to go through doing grunt-work to
fix all the other keyframes which now need to change as well.
So, this tool is now available in the following two places (in addition to
the existing Pose -> Propagate menu):
* Toolbar - The "Propagate" button will use the default mode (or the last
used mode for each subsequent invocation).
The arrow-button beside this will allow choosing between the different
modes. (NOTE: The UI team may have different thoughts on this, but,
let's give this a try for a while first, to see if this sort of thing works)
* Alt-P - In Pose Mode, this will now bring up a menu allowing you to choose
which mode is used. Since this sort of thing is something that does
get run several times in a row when you need it, having this hotkey
will make it a bit more convenient.
This commit adds a new mode for the Propagate Pose tool. With this new option,
the Propagate Pose will copy the current pose over to all selected keyframes
after the current frame.
For reference, some of the other/existing options are: to copy it to each subsequent
keyframe with the same value (WHILE_HELD - the default), to the next keyframe,
or to the last keyframe.
When in Stroke Edit Mode, an indicator/warning message is now shown in the top-right
corner to make it easier to notice that operations will apply to Grease Pencil
strokes instead.
* Moved the context handling stuff into gpencil_utils.c
* Moved the datablock and layer operators out into their own file too. Again,
these weren't related to the other stuff that much
* Split the GPencil to Curves operator out into its own file (gpencil_convert.c).
This was quite a massive blob of code (48kb) that was not that related to the
other operators still in that file (gpencil_edit.c)
Caused by changes in 31e26bb83b. This makes it fall back to the old
method if we can't find a screen.
Patch is actually by @LazyDodo with minor edits by me.
This works by using the distance in the x axis only (usually artists want to influence nearby
keyframes based on timing, not value). Tweaking handles is the same as tweaking
the central handle. It's a bit ambiguous if proportional editing is really meaningful
for handles but will leave that for artists to decide.
The issue has been here since we changed drawing code for meshes to use
vertex arrays instead of immediate mode when VBO was off. Basically we
should now always invalidate the GPU objects regardless of the VBO
setting in the preferences.
The bug has been there since 2.73 at least, but what made it apparent
now is that new version resets preferences and as an extension the VBO
flag.
Should be included in final 2.74 release
Typical error using '->next' member of a freed linked list item. A bit trickier
even here, since we have some recursion...
Trivial fix for nasty crasher, safe for 2.74 imho?
The return type of raise_exc_wheel() is bool, but the method return -1. The compiler will change the return type type to an int. This can cause some problems on 64bit systems.
