There were two problems:
* The stroke was deleted if the last point was selected. Now
the stroke is flipped because is faster.
* If the second point was selected, the first point was removed
because the internal api, removed one point strokes by
default. This was done becaus ethe tools that used this API
did not need one point strokes as result. Now this optional
and keep one point strokes.

This function allows to set the start point for cyclic strokes.
The function is required by a new modifier and operator
that are currently under development.
|
|
It's better to keep stroke as first parameter.
|
|
This makes the api more portable and not depend on
any visual area for background tasks like future modifiers.
|
|
Actually, when you increase the thickness of the stroke in the outline conversion, the shape of the stroke changes and becomes thicker.
This commit includes a new algorithm to correct this problem. A new `Keep Shape` parameter allows you to disable it because, for artist reasons, it may be good to keep the old algorithm and change the shape.

This patch makes the grease pencil smooth operation symmetric.
It also increases the performance a lot if strong smoothing is
required. Additionally there is an option for the position smooth
operation to keep the shape closer to the original for more iterations.
Since the result differs from the previous algorithm, versioning is used
to change the iterations and factor to match the old result.

1. Now handles cyclic strokes correctly.
2. Added a sharp threshold value to allow preservation of sharp corners.

his new modifier is equals to the existing mesh modifier but adapted to grease pencil.

When cut an stroke using the option Flat Caps, the falt was not done if the cut was done in the middle of the stroke.
Now the flat is applied to the segments created and also some cleanup of the code done.

Extend the stroke following an approximated circluar/helical curve.
This can be used as an effect for lineart or on its own as helix generator.

When joining two strokes in paint mode using the auto merge option, the join was very hard if the thickness was too different.
This patch adds a smooth to the join in order to get better transition.
Also fixed the problem to join existing strokes very far from actual stroke.
Some cleanup and rename of old code is included in order to make code more readable.

This patch adds the missing ability to keep the vertex groups when converting to a grease pencil object. This is increadible useful to create rigged grease pencil objects which move together with rigged meshes.

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)
Example of PDF export: https://youtu.be/BMm0KeMJsI4

This commit is a refactor of the fill tool to solve several problems we had since the first version of the tool.
Changes:
* The filling speed has been improved for each step of the process with the optimization of each algorithm/function.
* New `AutoFit` option to fill areas outside of the viewport. When enable, the total size of the frame is calculated to fit the filling area.
* New support multiframe filling. Now it is possible to fill multiple similar frames in one go.
* New `Stroke Extension` option to create temporary closing strokes. These strokes can be displayed and adjusted dynamically using wheel mouse or PageUp/Down keys.
* Parameter `Resolution` now is named `Precision` and has been moved to topbar.
* `Resolution` now has decimals and can be lower than 1 to allow quick filling in storyboarding workflows. Maximum value has been set as 5.
* Parameter `Simplify` has been moved to Advanced panel.
* Improved fill outline detection. In some cases, the outline penetrated the area to be filled with unexpected results.
* Fixes some corner case bugs with infinite loops.
As a result of this refactor, also these new functionalities has been added.
* New support for multiframe in `Draw` mode. Any drawing in active frame is duplicated to all selected frame.
* New multiframe display mode. Keyframes before or after of the active frame are displayed using onion colors. This can be disable using Onion overlay options.

This patch introduces a new BKE function that performs a uniform subdivide.
The goal of this function is to subdivide the stroke to reach a target number of points while maintaining its shape, color, and weights.
This is done by repeatedly subdividing the longest edge in the stroke. Every subdivision adds a new point at the exact middle point of an edge.
The function is intended to be used in the interpolation operators to give better results when interpolating between different sized strokes.

This option joins any stroke with an end near the actual stroke. Now it is not limited to the last stroke, any stroke in the same layer for the actual frame can be joined. The join can join two strokes drawing a third stroke.
If the end and the start of the result stroke are very small, the stroke is changed to be cyclic automatically.
There is a limit distance to join the stroke, if the distance is greater than this value, the strokes are not joined. Actually, a constant, threshold distance is used, but we could expose
as a parameter in the UI in the future.
The tool can be used with freehand drawing or with primitives.
Note: Great part of the patch is just a refactor of the old code to make it accessible and to keep code organized.

This patch is the result of the GSoC 2020 "Editing Grease Pencil Strokes
Using Curves" project. It adds a submode to greasepencil edit mode that
allows for the transformation of greasepencil strokes using bezier
curves. More information about the project can be found

There were some problems when converted several objects at the same time, especially with the material conversion. The problems were more visible when bake an animation with several objects at the same time.
* Now the layer name include the object name.
* Reorganize how the materials are generated including object name.
* Fix color not converted to sRGB.
* Avoid triangles when generate the stroke. This fix a draw manager issue and also add more geometry to use later.
* Code cleanup.

A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),
because they are used in other places.

When the mesh is linked, the materials can not be available or be the same assigned to mesh. Now, if the mesh is linked, a simple two materials conversion is used.
To get the full list of materials, the mesh must not be linked.
Also checked some indexes to be sure never get a wrong value and that materials are not created again and again.

This patch adds two options:
- Convert a mesh to grease pencil strokes.
- Bake the mesh animation into grease pencil strokes.
Both are related and must be included in the same patch.
Related to tasks: T77629 and T77630
Notice: The conversion is done for mesh edges and it's not considering any visibility clipping. All edges are exported, no matters if it's visible or not.
Example of Convert a Mesh to Grease Pencil strokes:

This conversion was inspired by the technique used by @luamono in this tweet: https://twitter.com/luamono/status/1239983662176841730
