c434782e3a File headers: SPDX License migration
Use a shorter/simpler license convention, stops the header taking so
much space.

While most of the source tree has been included

- `./extern/` was left out.

8fb2ff458b GPUShaderCreateInfo for interface abstraction
This is a first part of the Shader Create Info system could be.

A shader create info provides a way to define shader structure, resources
and interfaces. This makes for a quick way to provide backend agnostic
binding informations while also making shader variations easy to declare.

- Clear source input (only one file). Cleans up the GPU api since we can create a
  shader from one descriptor
- Resources and interfaces are generated by the backend (much simpler than parsing).
- Bindings are explicit from position in the array.
- GPUShaderInterface becomes a trivial translation of enums and string copy.
- No external dependency to third party lib.
- Cleaner code, less fragmentation of resources in several libs.
- Easy to modify / extend at runtime.
- no parser involve, very easy to code.
- Does not hold any data, can be static and kept on disc.
- Could hold precompiled bytecode for static shaders.

This also includes a new global dependency system.
GLSL shaders can include other sources by using #pragma BLENDER_REQUIRE(...).

This patch already migrated several builtin shaders. Other shaders should be migrated
one at a time, and could be done inside master.

There is a new compile directive `WITH_GPU_SHADER_BUILDER` this is an optional
directive for linting shaders to increase turn around time.

What is remaining:
- pyGPU API {T94975}
- Migration of other shaders. This could be a community effort.

This replaces header include guards with `#pragma once`.
A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),

This patch has been generated by P1561 followed by `make format`.

65ec7ec524 Cleanup: remove redundant, invalid info from headers
BF-admins agree to remove header information that isn't useful,
to reduce noise.

- BEGIN/END license blocks

  Developers should add non license comments as separate comment blocks.
  No need for separator text.

- Contributors

  This is often invalid, outdated or misleading
  especially when splitting files.

  It's more useful to git-blame to find out who has developed the code.

4452bea2f1 move Gawain library to intern
Before now it lived in source/blender/gpu for convenience. Only a few files in the gpu module use Gawain directly.

Tested on Mac, time to push and test on Windows.

Todo: some CMake magic to make it easy to
#include "gawain/some_header.h"
from any C or H file. Main problem here is the many editors that include GPU_immediate.h which includes Gawain's immediate.h -- is there a way to avoid changing every editor's CMakeLists?

b6bd299359 Gawain: reorganize source code
Put Gawain source code in a subfolder to make the boundary between the

Changed Gawain’s license from Apache to Mozilla Public License. Has

more files soon…)

18d49a8283 Gawain: add immBeginAtMost
immBegin requires us to know how many vertices will be drawn. Most times this is fine, but sometimes it can be tricky. Do we make the effort to count everything in one pass, then draw it in a second?

immBeginAtMost makes this simple. Example: I'll draw at most 100 vertices. Supply only 6 verts and it draws only 6.

Any unused space is reclaimed and given to the next immBegin.

immBindProgram automatically packs the vertex format if needed.
