There was a conflict between Object "In Front" and how the strokes were managed in Stroke panel for grease pencil datablock.
In order to keep consistency, the order of the object has been moved to Object level and now it's using the standard "In Front" flag. As all it is 3D, the option "Back" has been removed.
This also fixes the problem with task T62137.
Also related to commit 54ffc4e19d and D4405
Note: Things were working fine if you were to pin the Grease Pencil
object, but not if you were pinning the GP data.
In too many poll functions context.object was being requested when
a simple context.gpencil_data would suffit.
Panels that are still not showing in pinning:
* DATA_PT_gpencil_display.
The panel needs to be split in sub-panels, leaving all object-dependent
properties in its own panel so we can poll it away, while showing the
rest.
* * *
This commit doesn't handle greasepencil material. In this case I
recommend we do as properties_material.py and have a generous poll(),
followed by different drawing logics whether or not we have an object.
- Add a new panel to differentiate between viewport display and stroke options
- Use clearer naming for depth ordering and stroke thickness properties

Differential Revision: https://developer.blender.org/D4405
Add a new Draw Mode to display panel in order to define the z-.depth order of the strokes using the real 3D position and not the 2D layer position.
This change makes possible to use VR with grease pencil drawings because the depth of the strokes change with camera position. Also, provide an alternative solution to tasks: T57859, T60325,
The parameter only works with 3D space depth ordering. The Back and Front depths are incompatible with 3D Space mode.
Options are:
- Back
- Front
- 3D Space->2D Layers (default)
-3D Space->3D Location (new mode)
This commit groups a set of new tools that were tested in grease pencil object branch before moving to master. We decide to do all the development in a separated branch because it could break master during days or weeks before the new tools were ready to deploy.
The commit includes:
- New Cutter tool to trim strokes and help cleaning up drawings.
- New set of constraints and guides to draw different types of shapes. All the credits for this development goes to Charlie Jolly (@charlie), thanks for your help!
- Segment selection mode to select strokes between intersections.
- New operator to change strokes cap mode.
- New option to display only keyframed frames. This option is very important when fill strokes with color.
- Multiple small fixes and tweaks.
Thanks to @pepeland and @mendio for their ideas, tests, reviews and support.
Note: Still pending the final icons for Cutter in Toolbar and Segment Selection in Topbar. @billreynish could help us here?
Too many things done wrong in original rBd12b3767f81d to list them all
here, hopefully nothing bad sneaked in again this time :|
Also cleaned up a little the 'sort by name', even though (since we only
have two options by default, sort by index and by name) we can abuse it
as a binary option for now, this is not a bitflag...
Now it's possible define the blend mode between layers including the option to clamp the layer using underlying layers.
Also a new Simplify option has been added to disable blend layers.
Now the grid is always controlled by the topbar selector and not in the canvas panel. To have two places to define orientation was confuse.
The orientation by default (no lock) is always to view plane.
- Draw on back buttons moves near mode
- zDepth offset moved from View Panel to Popover
- Target for Stroke mode moved to popover
- New First point snap mode
After a lot of discussion about this option (see 18f1175940) we have decided set always the order of GP layers in 2D mode (Top->Down) and remove the parameter from User Preferences screen.
Internally all works equal, but in the UI the list is inverted.
The filter buttons to reverse the list or sort alphabetically have been removed because these buttons are not logic in this context.
Now by default the UVs are calculated with a fixed size and this makes easier to add patterns for drawings like Manga. Before, the texture changed depending of the stroke size.
The grid now can be configured by object because this helps to identify objects and allows to define diferent grid parameters for each objects.
Also added a color option.
This parameter allows to define the percentage of offset of a stroke when uses surface mode.
Before, this was a fixed value, but for some artists' purposes, it's good to have the option to change it.
The operator allows to copy a complete layer with all frames or only active frame to a new object.
Can be found in edit specials menu (W key) or in Layers specials menu (last button near layer list).
Add a general parameter to force the recalc of the triangulation data because some modifiers could change the geometry and the filling triangles would not be right.
Now, the parameter is visible in UI panel because this option reduces FPS, but maybe in the future we can keep always ON and remove the parameter.
The initial design assumed that there was only one object for each unique name, but that was not the case when instances were created.
Now, instances are supported and speed has been greatly improved when repetitions are used.
As a result of this change, the option to create objects has been removed in the Instances modifier. This option was strange and was also against Blender's design rules, since a modifier should never create objects. The old functionality of the modifier can be achieved with instances.
Also, several memory leakage problems that were not previously detected have been eliminated, and especially in the grid and in the drawing process
Onion Skin is not supported in multi-user datablocks. Support this, makes incompatible with instances. We need find a solution in the long term, but now it's better keep disabled and make instances work. Anyway, the new instances makes unnecessary to use muli-user datablocks.
