for removing unused material slots would then freeze.
Now return/cancel early in case of empty selection.

There was a function to set 2 pixels wide for inverse filling, but this must not be done in the borders of the image.
Now, the borders are checked before set 2 pixels.
Now if one stroke in the extremes of the stack is selected, other strokes are moved.

Previously it was not possible to subdivide the last segment of a cyclic
stroke.
The fix makes sure that the correct number of new points is calculated
correctly and adds the new points to the last segment.

When using the smooth operator, the thickness would not be
smoothed on the first iteration. This was becasue the inner loop
was set to run `r * 20` times but `r` starts at 0.
The fix makes sure that "Smooth Thickness" works on the first
iteration by using a fixed value of `20` as the loop limit. This
makes sure that for every iteration, we run the smoothing of the
thickness 20 more times.

Now `ED_view3d_backbuf_depth_validate`, `ED_view3d_draw_depth` and
`ED_view3d_draw_depth_gpencil` are unified in `ED_view3d_depth_override`.
This new function replaces `ED_view3d_autodist_init`.
Also, since `ED_view3d_depth_update` depends on the render context, and
changing the context is a slow operation, that function also was removed,
and the depth buffer cached is now updated inside the new unified drawing
function when the "bool update_cache" parameter is true.
Finally `V3D_INVALID_BACKBUF` flag has been renamed and moved to
`runtime.flag`.

The problem was produced because the strokes were selected, but the loop to clear this flag before applying cutter was using unlocked layers only, and the protected layer flag was not reset.
Now, the flag is reset for all layers, locked and unlocked.
When interpolate, the stroke order was not correct because it was assumed the GHash iter would return the items in the same order of insertion, but this is false.
Now, a list is used to keep the order of the strokes and the Hash is used to get the relationship between strokes as before.
Tracing images to grease pencil objects creates sometimes artifacts, as seen, for example, when tracing the attached image. {F9910821}
I have found the same behavior both in the 2.92 release and in the current 2.93 master.
The artifacts are caused by a variable that's not initialized or updated when finding a point tagged as POTRACE_CORNER.
This patch solves this issue.

This patch adds support to export and import grease pencil in several formats.
Inlude:
* Export SVG
* Export PDF (always from camera view)
* Import SVG
The import and export only support solid colors and not gradients or textures.
Requires libharu and pugixml.
For importing SVG, the NanoSVG lib is used, but this does not require installation (just a .h file embedded in the project folder)

This adds the LineArt grease pencil modifier.
It takes objects or collections as input and generates various grease
pencil lines from these objects with the help of the active scene
camera. For example it can generate contour lines, intersection lines
and crease lines to name a few.
This is really useful as artists can then use 3D meshes to automatically
generate grease pencil lines for characters, enviroments or other
visualization purposes.
These lines can then be baked and edited as regular grease pencil lines.

Before only it was only possible interpolate frames of `Keyframe` type. Now all types except `Breakdown` can be used.
`Breakdown` cannot be used because it would be impossible interpolate two times because the extremes of the interpolation would change and the clean operator would not work.
When adding a notifier, `reference` data can be passed. The notifier system
uses this to filter out listeners, for example if data of a scene changes,
windows showing a different scene won't get the notifiers sent to their
listeners.
For the `NC_SPACE` notifiers, a number of places also passed the space as
`reference`, but that wasn't used at all. The notifier would still be sent to
all listeners in all windows (and the listeners didn't use it either). Causing
some unnecessary updates (e.g. see ed2c4825d3).
With this commit, passing a space will make sure the notifier is only sent to
that exact space. Some code seems to already have expected that to be the case.
However there were some cases that passed the space as `reference` without
reason, which would break with this commit (meaning they wouldn't redraw or
update correctly).
Corrected these so they don't pass the space anymore.
Now, if the Autokey is not enabled, a new frame is not created and it is used the last active one. If no active frame, a message is displayed and the operation is canceled.
This is a common request for 2D artists.
Also, grease pencil was not working as Blender does in other areas.

In Blender, we used to use the term 'draw' to refer to information
displayed to the user. For version 2.80, it was decided to change these
instances to 'display' instead. This was to avoid the ambiguity between
end-user drawing tools and display options.
From the Oxford English Dictionary:
- Draw: produce (a picture or diagram) by making lines and marks on
paper with a pencil, pen, etc.
- Display: show (data or an image) on a computer, television, or
other screen.
Therefore, we should use draw when referring to drawing tools for
making marks, but use display when referring to information
shown/displayed to the user. From a user POV, the computer displays
certain information, whereas the user draws a mark.
Apparently this change was not implemented consistently, so this patch
changes all remaining relevant instances of "draw".

Multiply the two number together. If the sign of the result is positive, then the sign was the same. If the sign of the result is negative, then the signs were different.
Improved the calculation of the distances and changed the variable names to make it more readable.
Still, there are some corner cases that could be not handled properly, but we keep as is to test more real drawings to analyze if the small number of corner cases needs to be fixed or not.
Following with the changes included to interpolate strokes of different number of points, a full review has been done in the interpolation tools.
* Interpolate now is a tool and not an operator. It was not logic to have this tool as a button.
* Interpolate tool parameters have been moved to topbar.
* Interpolate popover has been removed from topbar and interpolate `Sequence` operator has been moved to grease pencil menu.
* Interpolate Sequence now include a Redo panel.
* Interpolate tool now allows to select the strokes by pairs. This allows to interpolate any stroke with any stroke and not as before that it was only possible by drawing order. If no stroke is selected, the interpolation is done as before.
* Now is possible interpolate again if a previous keyframe exist. Before, it was impossible to interpolate two times in same frame and this made impossible to do the interpolation by groups of frames.
* New automatic option to `Flip strokes` if the stroke and end are not in the right position. Also the flip can be set manually for corner cases.
* Cleanup of menus related to interpolate.
* Fixed some bugs and removed parameters from scene because now all are tool or operator contained.
* Some code cleanup and function renames.
This commit also includes the some codebase to future implementation of the concept `Vertex Active` that now does not exist in grease pencil.
