2022-06-08CMake: optionally disable OBJ, STL & GPencil SVG supportCampbell Barton
The following CMake options have been added (enabled by default), except for the lite build configuration. - WITH_IO_STL - WITH_IO_WAVEFRONT_OBJ - WITH_IO_GPENCIL (for grease pencil SVG importing). Note that it was already possible to disable grease pencil export by disabling WITH_PUGIXML & WITH_HARU. This is intended to keep the lite builds fast and small for building, linking & execution.

2022-06-03Compositor: add pre/post/cancel handlers and background job infoPhilipp Oeser
Main motivation is from T54314 where there was no way to read from a Viewer image datablock after the compositor has run. The only solution there was to do a full rerender (which obviously takes much longer). Adding a handler avoids having to rerender. This uses new syntax from rBf4456a4d3c97 and also adds "COMPOSITE" as a job type that can be queried by `bpy.app.is_job_running`. NOTE: there is another issue when multiple viewers are used and these get active via RNA (compo execution is not triggered there yet -- unlike when a viewer is selected in the Editor -- this is an issue of `ED_node_set_active` vs. only `nodeSetActive`, but this will be tackled separately) Maniphest Tasks: T54314 Differential Revision: https://developer.blender.org/D15078
2022-06-02Cleanup: remove "<pep8 compliant>" from headersCampbell Barton
It can be assumed that all scripts comply with basic pep8 formatting regarding white-space, indentation etc. Also remove note in best practices page & update `tests/python/pep8.py`. If we want to exclude some scripts from make format, this can be done by adding them to `ignore_files` in: source/tools/utils_maintenance/autopep8_format_paths.py Or using `# nopep8` for to ignore for individual lines.

2022-06-02PyDoc: reference enum instead of inliningCampbell Barton
2022-06-02Expose background job info to PythonSybren A. Stüvel
Add `bpy.app.is_job_running(job_type)` as high-level indicator. Job types currently exposed are `WM_JOB_TYPE_RENDER`, `WM_JOB_TYPE_RENDER_PREVIEW`, and `WM_JOB_TYPE_OBJECT_BAKE`, as strings with the `WM_JOB_TYPE_` prefix removed. The functions can be polled by Python code to determine whether such background work is still ongoing or not. Furthermore, new app handles are added for `object_bake_{pre,complete,canceled}`, which are called respectively before an object baking job starts, completes sucessfully, and stops due to a cancellation. Motivation: There are various cases where Python can trigger the execution of a background job, without getting notification that that background job is done. As a result, it's hard to do things like cleanups, or auto-quitting Blender after the work is done. The approach in this commit can easily be extended with other job types, when the need arises. The rendering of asset previews is one that's likely to be added sooner than later, as there have already been requests about this.

2022-05-26UI support for showing candidates for string propertiesCampbell Barton
Currently strings are used for cases where a list of identifiers would be useful to show. Add support for string properties to reference a callback to populate candidates to show when editing a string. The user isn't prevented from typing in text not found in this list, it's just useful as a reference. Support for expanding the following strings has been added: - Operator, menu & panel identifiers in the keymap editor. - WM operators that reference data-paths expand using the Python-consoles auto-complete functionality. - Names of keying sets for insert/delete keyframe operators. Details: - `bpy.props.StringProperty` takes an option `search` callback. - A new string callback has been added, set via `RNA_def_property_string_search_func` or `RNA_def_property_string_search_func_runtime`. - Addresses usability issue highlighted by T89560, where setting keying set identifiers as strings isn't practical. - Showing additional right-aligned text in the search results is supported but disabled by default as the text is too cramped in most string search popups where the feature would make sense. It could be enabled as part of other layout tweaks. Reviewed By: brecht Ref D14986
2022-05-25PyDoc: fix generated output for gpu.shaderCampbell Barton
Inclining built-in shader descriptions used the wrong indentation level. Link to the built-in shaders instead which avoids the indentation error and de-duplicates the list which is already shown on the page.

2022-05-20CMake: fix AUDASPACE disabling WITH_PYTHON for BlenderCampbell Barton
When AUDASPACE couldn't find NUMPY, it would disable WITH_PYTHON for the rest of Blender. Now setting the value globally is only done for standalone AUDASPACE builds. Now it's possible to build Blender with AUDASPACE & PYTHON but without NUMPY. While this isn't an especially important configuration to support, having Python mysteriously disabled is a hassle to troubleshoot. NOTE: extern/audaspace/CMakeLists.txt has become out sync with the original [0], it seems this is being maintained in our repository.

2022-05-09EEVEE & Viewport: Add a built-in shader called 3D_IMAGE, and expose to the ↵Shashank Shekhar
python API Adds an example python script to the documentation for the 3D_IMAGE shader. The **use-case** is to draw textures with 3D vertex positions, in XR views as well as non-XR views (in a simpler manner). **Testing**: I've tested that this compiles and works on my Macbook (with the example python script included in this change). I don't have access to a Windows or Linux machine right now, but this change doesn't look platform-specific and no new glsl shaders have been added or edited by this change. I'll try to get access to a Windows machine, but if someone does have one, I'd be really grateful if they could try this change. Thanks! **Problem addressed**: The existing 2D_IMAGE shader (exposed in the python API) gets near-clipped when drawn in the XR view, regardless of the near-clip settings. Additionally, the 2D_IMAGE shader only accepts 2D positions for the image vertices, which means drawing textures in 3D requires providing 2D coordinates and then pushing a transform-rotate-scale matrix to the GPU, even for non-XR (i.e. WINDOW) views. The 3D_IMAGE shader is simpler: it accepts 3D vertex positions, and doesn't require any additional work by the scripter. **Workaround**: The current workaround is to use custom shaders in the python script. **Non-intrusive change**: No new glsl shaders were added. This change just bundles two existing shaders: the vertex shader used by the 3D_IMAGE_MODULATE_ALPHA shader, and the fragment shader used by the 2D_IMAGE shader.

As `GPU_PRIM_LINE_LOOP` is not supported on Vulkan or Metal and `GPU_PRIM_TRI_FAN` is not supported on Metal, they will be removed in future releases. So it is important to inform users that they are obsolete and may not be supported for a long time.
