This patch updates the timeline editor. Ordinarily, it draws the
yellow keyframe lines at 100% of the available height. This becomes an
issue when there are keyframes for every frame, which can happen when
importing motion capture data or recording animations from the BGE. In
such cases, the green "current frame" indicator becomes very hard to
see.
This patch restricts the drawing to the bottom 60% of the available
space, thereby making the "current frame" indicator more visible.

This merge-commit brings in a number of new features and workflow/UI improvements for
working with Grease Pencil. While these were originally targetted at improving
the workflow for creating 3D storyboards in Blender using the Grease Pencil,
many of these changes should also prove useful in other workflows too.
The main highlights here are:
1) It is now possible to edit Grease Pencil strokes
- Use D Tab, or toggle the "Enable Editing" toggles in the Toolbar/Properties regions
to enter "Stroke Edit Mode". In this mode, many common editing tools will
operate on Grease Pencil stroke points instead.
- Tools implemented include Select, Select All/Border/Circle/Linked/More/Less,
Grab, Rotate, Scale, Bend, Shear, To Sphere, Mirror, Duplicate, Delete.
- Proportional Editing works when using the transform tools
2) Grease Pencil stroke settings can now be animated
NOTE: Currently drivers don't work, but if time allows, this may still be
added before the release.
3) Strokes can be drawn with "filled" interiors, using a separate set of
colour/opacity settings to the ones used for the lines themselves.
This makes use of OpenGL filled polys, which has the limitation of only
being able to fill convex shapes. Some artifacts may be visible on concave
shapes (e.g. pacman's mouth will be overdrawn)
4) "Volumetric Strokes" - An alternative drawing technique for stroke drawing
has been added which draws strokes as a series of screen-aligned discs.
While this was originally a partial experimental technique at getting better
quality 3D lines, the effects possible using this technique were interesting
enough to warrant making this a dedicated feature. Best results when partial
opacity and large stroke widths are used.
5) Improved Onion Skinning Support
- Different colours can be selected for the before/after ghosts. To do so,
enable the "colour wheel" toggle beside the Onion Skinning toggle, and set
the colours accordingly.
- Different numbers of ghosts can be shown before/after the current frame
6) Grease Pencil datablocks are now attached to the scene by default instead of
the active object.
- For a long time, the object-attachment has proved to be quite problematic
for users to keep track of. Now that this is done at scene level, it is
easier for most users to use.
- An exception for old files (and for any addons which may benefit from object
attachment instead), is that if the active object has a Grease Pencil datablock,
that will be used instead.
- It is not currently possible to choose object-attachment from the UI, but
it is simple to do this from the console instead, by doing:
context.active_object.grease_pencil = bpy.data.grease_pencil["blah"]
7) Various UI Cleanups
- The layers UI has been cleaned up to use a list instead of the nested-panels
design. Apart from saving space, this is also much nicer to look at now.
- The UI code is now all defined in Python. To support this, it has been necessary
to add some new context properties to make it easier to access these settings.
e.g. "gpencil_data" for the datablock
"active_gpencil_layer" and "active_gpencil_frame" for active data,
"editable_gpencil_strokes" for the strokes that can be edited
- The "stroke placement/alignment" settings (previously "Drawing Settings" at the
bottom of the Grease Pencil panel in the Properties Region) is now located in
the toolbar. These were more toolsettings than properties for how GPencil got drawn.
- "Use Sketching Sessions" has been renamed "Continuous Drawing", as per a
suggestion for an earlier discussion on developer.blender.org
- By default, the painting operator will wait for a mouse button to be pressed
before it starts creating the stroke. This is to make it easier to include
this operator in various toolbars/menus/etc. To get it immediately starting
(as when you hold down DKEy to draw), set "wait_for_input" to False.
- GPencil Layers can be rearranged in the "Grease Pencil" mode of the Action Editor
- Toolbar panels have been added to all the other editors which support these.
8) Pie menus for quick-access to tools
A set of experimental pie menus has been included for quick access to many
tools and settings. It is not necessary to use these to get things done,
but they have been designed to help make certain common tasks easier.
- Ctrl-D = The main pie menu. Reveals tools in a context sensitive and
spatially stable manner.
- D Q = "Quick Settings" pie. This allows quick access to the active
layer's settings. Notably, colours, thickness, and turning
onion skinning on/off.

Separates graphics context creation from window code in Ghost so that they can vary separately.

This space did not refresh on NC_OBJECT, ND_BONE_SELECT notifier...

Opted to keep includes if they are used indirectly (even if removing is possible).

viewable keyframes
Made the timeline option to only show keyframes from selected channels/data be a
per-scene setting instead of the per-timeline option it was previously. This makes
it easier for animators working on rigs with multiple bones (especially during the
polishing phase), since now the timeline and jump to keyframe operators use the same
setting to decide which subset of keyframes they need to consider.
By default, this option is enabled by default.
TODO: Extend this to the keyframe status shading on the active object name in the 3D view?

too short."
This reverts own commit e9d733a8bd9ebf803d4afac419670974792a3c0d.
Turns out there is no consensus here, better to open a design task. :/

Just using same principle as the one already used for the 'cache bar': add -0.5/+0.5 offsets to start/end (also edited 'view all' op to match this).
|

|
|
This got broken in 58217, but before that it only worked by accident because
of a missing break statement in a switch.
|
|
|
|
indent.
also indent case's within the switch (we already did both of these almost everywhere)
|
|
were falling through when its obviously incorrect to do so.
|
|
node materials.
Area and region listener callbacks now get the screen and area pointers passed, so
they can do more fine grained checks to see if redraw is really needed, for example
depending on the 3D view drawtype.
|
|
|
|
remove MEM_sys_types.h which was a duplicate.
|
|
include conflicts later on.
|
|
for more editors: timeline, graph, action, NLA, sequencer, image, clip.
|
|
Add read/write/interpolate functions.
In order to get rigid body point cache id from object it's now required to pass the
scene to BKE_ptcache_ids_from_object().
Rigid body cache is drawn in the orange color of the bullet logo.
|
|
Also changed shebang to '#!/usr/bin/env python', this is more portable across unixes...
|
|
Timeline didn't update after deleting keyframes using Alt-I in the 3D View (i.e.
after ANIM_OT_keyframe_delete_v3d)
|
|
|
|
|
|
|
|
replace do prefix with do_ for bool vars.

start frame = end frame which is useful in some cases.
Also made behavior of S/E operators equal to sliders in timeline.
|
|
|
|
without the underscores these clogged up the namespace for autocompleation which was annoying.
|
|
|
|
now there are no more use of deprecated struct member warnings.
|
|
|
|
* Some cleanup, removed references to already deleted *_header.c files.
* Marked SpaceScript as deprecated and removed header. Will keep space for now though, as some script operators are there and Campbell might want to re-use the space later.
