d5d3dc4189 GPencil: Use default material when slot material is empty
When a material slot is empty, the default material is used.

The default color used is Gray to get a good contrast in dense scenes with dark and white background.

beab06b242 GPencil: Change UI scale for z-depth offset
Actually, the value for this parameter must be in the order of 0.00001 and this makes the UI uncomfortable.

Now, the value is divided by 1000 internally and the UI values are more logic.

85f90ed6fd Fix T68723: GPencil - Split Select mode for Sculpt and Edit mode
Actually, the selection mode is not visible in Sculpt mode when mask is enabled, but still is used.
Also, the mode is shared between Edit mode and Sculpt mode and for meshes the selector is by mode.

This commit splits the select mode in different properties and show the selector in Sculpt mode to define the Select mode. Also, the Select Mask button has been removed and now the Select Mode buttons work equal to Meshes where the select buttons are the mask enable too.

Fixed some old code not valid detected during these changes.

3566b81c8b Refactor access to dependency graph
This change ensures that operators which needs access to evaluated data
first makes sure there is a dependency graph.

Other accesses to the dependency graph made it more explicit about
whether they just need a valid dependency graph pointer or whether they
expect the graph to be already evaluated.

This replaces OPTYPE_USE_EVAL_DATA which is now removed.

Some general rules about usage of accessors:

- Drawing is expected to happen from a fully evaluated dependency graph.
  There is now a function to access it, which will in the future control
  that dependency graph is actually evaluated.

  This check is not yet done because there are some things to be taken
  care about first: for example, post-update hooks might leave scene in
  a state where something is still tagged for update.

- All operators which needs to access evaluated state must use
  CTX_data_ensure_evaluated_depsgraph().

  This function replaces OPTYPE_USE_EVAL_DATA.

  The call is generally to be done in the very beginning of the
  operator, prior other logic (unless this is some comprehensive
  operator which might or might not need access to an evaluated state).

  This call is never to be used from a loop.

  If some utility function requires evaluated state of dependency graph
  the graph is to be passed as an explicit argument. This way it is
  clear that no evaluation happens in a loop or something like this.

- All cases which needs to know dependency graph pointer, but which
  doesn't want to actually evaluate it can use old-style function
  CTX_data_depsgraph_pointer(), assuming that underlying code will
  ensure dependency graph is evaluated prior to accessing it.

- The new functions are replacing OPTYPE_USE_EVAL_DATA, so now it is
  explicit and local about where dependency graph is being ensured.

This commit also contains some fixes of wrong usage of evaluation
functions on original objects. Ideally should be split out, but in
reality with all the APIs being renamed is quite tricky.

Fixes T67454: Blender crash on rapid undo and select

Speculation here is that sometimes undo and selection operators are
sometimes handled in the same event loop iteration, which leaves
non-evaluated dependency graph.

Fixes T67973: Crash on Fix Deforms operator
Fixes T67902: Crash when undo a loop cut

7f29fc7415 Fix T65691: GPencil Drawing long strokes turn invisible
There was a fixed limit to the number of points available in a buffer stroke.

Now, the array is expanded as needed using a predefined number of points for each expansion, instead to add one by one. This is done to reduce the number of times the memory allocation is required.

As part of the fix, some variables have been renamed to reflect better their use.

9270c15af8 GPencil: Get current frame from scene
This change makes it so current frame is queried from a scene rather
than from a dependency graph. This makes it possible to avoid the
fact that dependency graph might not be fully evaluated yet.

There are still some cases where it frame is queried from the graph,
but those seems to be in a code path where we need to ensure valid
dependency graph anyway.

This reverts commit a412f49e75 and 873c756e5d. The change was only

240940c58c GPencil: New Dots gradient
This commit adds support for drawing Dots strokes with a gradient factor to get artistic effects like watercolor.

Currently, the option is only supported by Dots materials, and in the future will be added to line strokes, but now there is a limitation on drawing engine and we will keep disabled on Line materials.

Also, added the option to align Dots and Boxes strokes textures aligned with the drawing path to get more fluid strokes.

d40581a714 GPencil: Improve drawing feeling in big files
When drawing in big files, the first points of the stroke were not smooth because the system was doing a copy of the depsgraph datablock.

Now, the depsgraph is not updated at the beginning and the feeling is far better, especially for big files.

To avoid the copy, the original datablock is used while drawing, because it's faster the lookup of the original data, than a full datablock copy.

Also some cleanup of the code.

6577618d5b GPencil: Changes in Fill and new 3D Cursor View Plane
This commit groups several options that were tested in grease pencil branch:

- Changes to fill algorithms and improves, specially in small areas and stroke corners.
  New options has been added in order to define how the fill is working and internally there are optimizations in detect the small areas in the extremes.

  Kudos to @charlie for coding this fill improvements.

- New 3D cursor view plane option.

  Now it's possible to lock the drawing plane to the 3D cursor and use the 3D cursor orientation. This allows more flexibility when you are drawing and reduce the need to create geometry to draw over surfaces.

- Canvas Grid now can be locked to 3D cursor.
- New option to reproject stroke using 3D cursor.
- Small tweaks and fixes.
