This applies changes from the 3D view circle select to other operators.

While \file doesn't need an argument, it can't have another doxy
command after it.
|
|
Move \ingroup onto same line to be more compact and
make it clear the file is in the group.

Needed for clan-format not to wrap onto one line.

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.

Prevents clang-format wrapping text before comments.

With the new automatic handle algorithm, it is possible to do a lot
of the animation via keyframes without touching the curves. It is
however necessary to change the keyframe interpolation and handle
types in certain cases. Currently the dopesheet/action editor
allows changing the types, but does not show them in any way.
To fix, add a new menu option to display this information. For handle
type, it is represented using the shape of the key icons: diamond for
Free, clipped diamond for Aligned, square for Vector, circle for Auto
Clamp, and cirle with dot for Automatic.
Non-bezier interpolation is a property of intervals between keys,
so it is marked by drawing lines, similar to holds. In this initial
version, only the fact of non-bezier interpolation is displayed,
without distinguishing types. For summaries, the line is drawn at
half alpha if not all curves in the group are non-bezier.
In addition, it is sometimes helpful to know the general direction
of change of the curve, and which keys are extremes. This commit
also adds an option to highlight extremes, based on comparing the
keyed values with adjacent keys. Half-intensity display is used
for overshot bezier extremes, or non-uniform summaries.

Computation of hold blocks was done by storing ranges (with start and
an end, and likely overlapping) in a tree keyed only by the block start.
This cannot work well, and there even were comments that it is not
reliable in complex cases.
A much better way to deal with it is to split all ranges so they don't
overlap. The most thorough way of doing this is to split at all and every
known keyframe, and in this case the data can actually be stored in the
key column data structures, avoiding the need for a second tree.
In practice, splitting requires a pass to copy this data to newly added
keys, and the necessity to loop over all keyframes in the range being
added. Both are linear and don't add excess algorithmic complexity.
The new implementation also calls BLI_dlrbTree_linkedlist_sync for
its own needs, so the users of the *_to_keylist functions don't have
to do it themselves anymore.

Add tool options to control how select operates (add/sub/set/and/xor).
Note: edit mode armature select still needs to support all options,
this is complicated by how it handles partial end-point selection.

This commit merge the full development done in greasepencil-object branch and include mainly the following features.
- New grease pencil object.
- New drawing engine.
- New grease pencil modes Draw/Sculpt/Edit and Weight Paint.
- New brushes for grease pencil.
- New modifiers for grease pencil.
- New shaders FX.
- New material system (replace old palettes and colors).
- Split of annotations (old grease pencil) and new grease pencil object.
- UI adapted to blender 2.8.
You can get more info here:
https://code.blender.org/2017/12/drawing-2d-animation-in-blender-2-8/
https://code.blender.org/2018/07/grease-pencil-status-update/
This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible.
Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton.

Also update menu items, adding select/de-select.
|
|
There's much more work to be done here, this is just fixing some obvious ones.
|
|
|
|
Strip unindented comment blocks - mainly headers to avoid conflicts.

While it is necessary to ignore duplicates when doing Deselect/Column Select
(where double-updates may result in nothing being selected), for borderselect,
not including the duplicates meant that sometimes, nothing would happen
if you were trying to borderselect keyframes originating from hidden channels.
This was first noticed in the greasepencil-object branch, but affects all
animation channel types.

Some of these API's can have 3D versions, explicitly name them 2D.
|
|
We can't have more than one NOTE_SUBTYPE in the same notifier.
Instead of calling both subtypes the code end up not calling either.
|
|
Practically all access to enum data is read-only.
|
|
Border and circle select wait for input by default.
This commit uses bool properties on the operators instead of
magic number (called "gesture_mode").
Keymaps that define 'deselect' for border/circle select
begin immediately, exiting when on button release.
|
|
Use same convention as all others.
Remove 'select' since these are used for zoom as well.
|
|
In preparation for modal operators storing their properties,
no need to keep mouse-paths around.
Also use generic function for lasso properties.
|
|
Replace with operator type 'last_properties'.
Also use generic function for circle gesture properties.
|
|
"datablock" channels even though those weren't visible
This meant that it was easy to accidentally select too many keyframes
|
|
|
|
This commit introduces a scale factor setting for scaling all keyframe indicators
in the Dopesheet Editor up/down, in order to make them easier to select. It is perhaps
most useful for keyframe types which are usually indicated using smaller keyframes
(e.g. breakdown), which may get tricky to quickly select.
|
|
|
|
Adapted from the code for Grease Pencil (just like the whole mode was)
|
|
To get this working the least effort, I've had to expose the helper functions
used by the lasso and circle select keyframe-test callbacks (which are generic)
and expose them for use by the GP keyframe editing code too. Hopefully in time
we clean this all up and just write the code once to operate on "keyframes"
|
|
This only works in the Action and Dopesheet modes (which operate on FCurve keyframes).
Support for Grease Pencil and Mask Keyframes though is still pending.

on Summary Tracks
|

TweakMode
When in TweakMode on NLA strips that had an offset, it was not possible to select
those keyframes in the Summary Channel in the Dope Sheet.
The main gist of it is that the current code is from before the summary track was
introduced, and so could assume that ANIM_nla_mapping_get() would work for all channels
present. Thus, simply converting the clicked frame to nla-mapped time once would be
enough. However, for summary channels, nla-mapping_get() doesn't do anything, since
we can potentially include keyframes from several different objects!
|
|
This brings them into line with other editing tools (e.g. object/mesh selection),
and should help fix bugs like T45374 and T45846
|
|
Using the standard "FCurve" animchannel type didn't work that well for
the control FCurves on NLA Strips, as the paths would not resolve correctly,
and the indentation was wrong. Also, there would likely be issues down the
track with applying NLA mapping. Hence, it's easier to just create a separate
type for this case, and adapt the rest of the code to also consider these (todo).
|
|
NLA Strips
NLA mapping corrections were being applied twice, causing column select to fail
|
|
|
|
Opted to keep includes if they are used indirectly (even if removing is possible).

View2D had some inconsistencies making it error prone in some cases.
- Inconstant checking for NULL x/y args.
Disallow NULL args for x/y destination pointers, instead add:
- UI_view2d_region_to_view_x/y
- UI_view2d_view_to_region_x/y
- '_no_clip' suffix wasn't always used for non-clipping conversion,
switch it around and use a '_clip' suffix for all funcs that clip.
- UI_view2d_text_cache_add now clips before adding cache.
- '_clip' funcs return a bool to quickly check if its in the view.
- add conversion for rectangles, since this is a common task:
- UI_view2d_view_to_region_rcti
- UI_view2d_region_to_view_rctf

rename change/is_change/is_changed/modified -> changed
also use bools over int/short/char and once accidental float.
|

Action Constraints
|
|
DopeSheet too
Previously, it only worked in the Graph Editor, though I thought I had
implemented it here too.
|

indent.
also indent case's within the switch (we already did both of these almost everywhere)
