c1b85103fe GPU: Added testcase for SSBO/Compute.
Test case is a smaller step towards supporting Vulkan. Other
test cases rely on SSBOs as well so it is better to first satisfy
this step before handling the others.

87a923fdb6 GPU: Add SSBO binding test to new structure.
This test was added to test the shader info structure binding
information for SSBOs. It still used the legacy GLSL structure.

ce13d0d326 GPU: Only compile test shaders when test cases option is enabled.
The glsl files + create infos of shaders that are only used
during development where still being compiled into blender.

This isn't needed and shouldn't be included. This change will
only include them when WITH_GTEST and WITH_OPENGL_DRAW_TESTS are
enabled. All other cases those files will be skipped.

d4d4efd3d3 GPU: Use create info for compute test cases.
Compute test case still used legacy API to construct
GLSL shaders. This change will migrate it to use the
GPUShaderCreateInfo's.

In preparation to run test-cases against non-opengl
back-ends.

125b283589 GPU: Add Math libraries to GPU shaders code
This implement most of the functions provided by the BLI math library.
This is part of the effort to unify GLSL and C++ syntax. Ref T103026.

This also adds some infrastructure to make it possible to run GLSL shader unit
test.

Some code already present in other libs is being copied to the new libs.
This patch does not make use of the new libs outside of the tests.

Note that the test is still crashing when using metal.

a296b8f694 GPU: replace GLEW with libepoxy
With libepoxy we can choose between EGL and GLX at runtime, as well as
dynamically open EGL and GLX libraries without linking to them.

This will make it possible to build with Wayland, EGL, GLVND support while
still running on systems that only have X11, GLX and libGL. It also paves
the way for headless rendering through EGL.

libepoxy is a new library dependency, and is included in the precompiled
libraries. GLEW is no longer a dependency, and WITH_SYSTEM_GLEW was removed.

Includes contributions by Brecht Van Lommel, Ray Molenkamp, Campbell Barton
and Sergey Sharybin.

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

Follow the SPDX license specification: https://spdx.org/licenses

While most of the source tree has been included

- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they
  use different header conventions.

doc/license/SPDX-license-identifiers.txt has been added to list SPDX all
used identifiers.

f53bd31690 Cleanup GPU/Draw test cases.
In preparation of supporting vulkan. Draw/GPU tests should use
GPU_TEST or DRAW_TEST macros. These macros will run the test
on available drawing context backends like OpenGL or Vulkan.

As in master there is only an OpenGL backend nothing changed.

87055dc71b GPU: Compute Pipeline.
With the compute pipeline calculation can be offloaded to the GPU.
This patch only adds the framework for compute. So no changes for users at
this moment.

NOTE: As this is an OpenGL4.3 feature it must always have a fallback.

Use `GPU_compute_shader_support` to check if compute pipeline can be used.
Check `gpu_shader_compute*` test cases for usage.

This patch also adds support for shader storage buffer objects and device only
vertex/index buffers.

An alternative that had been discussed was adding this to the `GPUBatch`, this
was eventually not chosen as it would lead to more code when used as part of a
shading group. The idea is that we add an `eDRWCommandType` in the near
future.
