License headers: add SPDX licenses for '*.glsl' files When GLSL sources were first included in Blender they were treated as data (like blend files) and had no license header. Since then GLSL has been used for more sophisticated features (EEVEE & real-time compositing) where it makes sense to include licensing information. Add SPDX copyright headers to *.glsl files, matching headers used for C/C++, also include GLSL files in the license checking script. As leading C-comments are now stripped, added binary size of comments is no longer a concern. Ref !111247

Overlay Engine: Refactor & Cleanup This is the unification of all overlays into one overlay engine as described in T65347. I went over all the code making it more future proof with less hacks and removing old / not relevent parts. Goals / Acheivements: - Remove internal shader usage (only drw shaders) - Remove viewportSize and viewportSizeInv and put them in gloabl ubo - Fixed some drawing issues: Missing probe option and Missing Alt+B clipping of some shader - Remove old (legacy) shaders dependancy (not using view UBO). - Less shader variation (less compilation time at first load and less patching needed for vulkan) - removed some geom shaders when I could - Remove static e_data (except shaders storage where it is OK) - Clear the way to fix some anoying limitations (dithered transparency, background image compositing etc...) - Wireframe drawing now uses the same batching capabilities as workbench & eevee (indirect drawing). - Reduced complexity, removed ~3000 Lines of code in draw (also removed a lot of unused shader in GPU). - Post AA to avoid complexity and cost of MSAA. Remaining issues: - ~~Armature edits, overlay toggles, (... others?) are not refreshing viewport after AA is complete~~ - FXAA is not the best for wires, maybe investigate SMAA - Maybe do something more temporally stable for AA. - ~~Paint overlays are not working with AA.~~ - ~~infront objects are difficult to select.~~ - ~~the infront wires sometimes goes through they solid counterpart (missing clear maybe?) (toggle overlays on-off when using infront+wireframe overlay in solid shading)~~ Note: I made some decision to change slightly the appearance of some objects to simplify their drawing. Namely the empty arrows end (which is now hollow/wire) and distance points of the cameras/spots being done by lines. Reviewed By: jbakker Differential Revision: https://developer.blender.org/D6296

GPU: Shader: Make info files generated This is the first step of moving the create infos back inside shader sources. All info files are now treated as source files. However, they are not considered in the include tree yet. This will come in another following PR. Each shader source file now generate a `.info` file containing only the create info declarations. This renames all info files so that they do not conflict with their previous versions that were copied (non-generated). Pull Request: https://projects.blender.org/blender/blender/pulls/146676

GPU: Change GLSL include directive This changes the include directive to use the standard C preprocessor `#include` directive. The regex to applied to all glsl sources is: `pragma BLENDER_REQUIRE\((\w+\.glsl)\)` `include "$1"` This allow C++ linter to parse the code and allow easier codebase traversal. However there is a small catch. While it does work like a standard include directive when the code is treated as C++, it doesn't when compiled by our shader backends. In this case, we still use our dependency concatenation approach instead of file injection. This means that included files will always be prepended when compiled to GLSL and a file cannot be appended more than once. This is why all GLSL lib file should have the `#pragma once` directive and always be included at the start of the file. These requirements are actually already enforced by our code-style in practice. On the implementation, the source needed to be mutated to comment the `#pragma once` and `#include`. This is needed to avoid GLSL compiler error out as this is an extension that not all vendor supports. Rel #127983 Pull Request: https://projects.blender.org/blender/blender/pulls/128076

Overlay-Next: Initial implementation This contains the basis of the new overlay engine. Only a few overlays are ported for proof of concept of the new design. This new design unifies the selection drawing with the overlay-next engine. It now becomes responsible of selection in object mode. For this we create a dedicated shader module that patches the shaders for selection. Note that the gizmo selection still uses the occlusion queries and edit-mode the current selection engine (select_engine.c).
