2022-03-22Fix T96308: Mesh to BMesh conversion doesn't calculate vertex normalsHans Goudey
Currently there is a "calc_face_normal" argument to mesh to bmesh conversion, but vertex normals had always implicitly inherited whatever dirty state the mesh input's vertex normals were in. Probably they were most often assumed to not be dirty, but this was never really correct in the general case. Ever since the refactor to move vertex normals out of mesh vertices, cfa53e0fbeed7178c7, the copying logic has been explicit: copy the normals when they are not dirty. But it turns out that more control is needed, and sometimes normals should be calculated for the resulting BMesh. This commit adds an option to the conversion to calculate vertex normals, true by default. In almost all places except the decimate and edge split modifiers, I just copied the value of the "calc_face_normals" argument. Differential Revision: https://developer.blender.org/D14406

2022-03-14Auto-generate RNA-structs declarations in `RNA_prototypes.h`Julian Eisel
So far it was needed to declare a new RNA struct to `RNA_access.h` manually. Since 9b298cf3dbec we generate a `RNA_prototypes.h` for RNA property declarations. Now this also includes the RNA struct declarations, so they don't have to be added manually anymore. Differential Revision: https://developer.blender.org/D13862 Reviewed by: brecht, campbellbarton

2022-03-14GPencil: Fix offset modifier negative scale thicknessHenrik Dick
If the scale in the offset modifier was set to a value lower than -1, the object would get mirrored. The problem was, that the thickness was set to 0 by that. This fix makes the thickness calculation only use the absolute values. Differential Revision: http://developer.blender.org/D14324

2022-03-08GPencil: New "Additive" mode for build modifierMarc Chéhab
The new mode only builds the new strokes in each frame. The code is assuming somebody uses "additive" drawing, so that each frame is different only in its NEW strokes. Already existing strokes are skipped. I used a simple solution: Count the number of strokes in the previous frame and ignore this many strokes in the current frame.

2022-02-18Cleanup: Rename original curve object type enumHans Goudey
This commit renames enums related the "Curve" object type and ID type to add `_LEGACY` to the end. The idea is to make our aspirations clearer in the code and to avoid ambiguities between `CURVE` and `CURVES`. Ref T95355 To summarize for the record, the plans are: - In the short/medium term, replace the `Curve` object data type with `Curves` - In the longer term (no immediate plans), use a proper data block for 3D text and surfaces.

2022-02-10Fix T95458: Line art ignores curve objects with no evaluated meshHans Goudey
Some curve objects don't have an evaluated mesh at all, but line art currently assumes that all curve objects have one before converting it to a mesh internally. Fix this by checking if the curve object has an evaluated mesh before skipping it. The remaining problem is that evalauted from non-mesh objects or evaluated curves from non-curve objects, etc. will be ignored if "Allow Duplicates" is off. That's a different problem though.

2021-11-23Fix broken handling of constraints reordering with library overridesJulian Eisel
Alternative to D13291 (description partially copied from there). New drag & drop reordering code would call constraints reordering operator with the generic context, and not the one from the panel's layout. missing the "constraint" member which is mandatory for poll function to properly deal with override vs. local constraints. For this to work in a decent way, there needs to be some panel-wide context that we can restore when executing callbacks outside of the normal draw context. So similar to uiLayoutSetContextPointer() to set context on a layout level, this introduces UI_panel_context_pointer_set() for panel level context (this calls the former for the current panel root layout as well).
