Guard shader storage related gets and bypass a buggy enum.
Fix T95592 OpenGL Invalid Enum

This option lets specify explicitely how the fragment shader will change
the fragment's depth.

Metal shading language follows the C++ 14 standard and in some cases requires a greater level of explicitness than GLSL. There are also some small language differences:
- Explicit type-casts (C++ requirements)
- Explicit constant values (C++ requirements, e.g. floating point values using 0.0 instead of 0).
- Metal/OpenGL compatibility paths
- GLSL Function prototypes
- Explicit accessors for vector types when sampling textures.

Adding WITH_METAL option to CMAKE to guard compilation for macOS only. Implemented stub METALBackend to mirror GPUBackend interface and added capabilities initialisation, along with API initialisation paths.
Global rendering coordination commands added to backend with GPU_render_begin and GPU_render_end() commands globally wrapping GPU work. This is required for Metal to ensure temporary resources are generated within an NSAutoReleasePool and freed accordingly.

implementation-defined value of `GL_MAX_TEXTURE_MAX_ANISOTROPY_EXT`
Allow the user to set an anisotropic filtering setting below the implementation-defined value of `GL_MAX_TEXTURE_MAX_ANISOTROPY_EXT`.
This bug-fix is also needed for 2.93 LTS.

This uses a StorageBuf as the source of indirect dispatch argument.
The user needs to make sure the parameters are in the right order.
There is no support for argument offset for the moment as there is no
need for it. But this might be added in the future.
Note that the indirect buffer is synchronized at the backend level. This is
done for practical reasons and because this feature is almost always used
for GPU driven pipeline.
|
|
This is a faster way to clear a buffer instead of reuploading new data.
It is equivalent to `memset` and runs directly on the GPU.
This is better to clear huge buffers and to avoid the sync cost of data upload.
|
|
|
|
This adds the possibility to read the stencil buffer inside shaders.
This is only available on GL 4.3 so use it accordingly.
|
|
This was getting in the way in multiple instances. Compute shaders dispatch
are still made in the presence of the last bound framebuffer even if they
do not interact with it.
|
|
|
|
|
|
|
|
Almost 1:1 identical to UniformBuf implementation.
|
|
This adds detection of the maximum number of shader storage buffer
bindings that is supported on the current platform. This can be
useful to turn off features that require compute shaders but use
more buffer bindings than available.

Some drivers for legacy platforms seem to have issues with compute
shaders, as revealed by T94936. This disables compute shader for the
known drivers where this issue is present. It is not clear if the issue
is Windows only or not, so this disable them for all operating systems.
See T94936 for a list of configurations where the issue is reproducible
or not.

This is an OpenGL 4.3 feature that enables creating a texture using a range
of the same data as another texture.
|
|
This means textures need to have the number of mipmap levels specified
upfront. It does not mean the data is immutable.
There is fallback code for OpenGL < 4.2.
Immutable storage will enables texture views in the future.

This can happen when the attribute has been optimized out by the compiler.
|
|
|
|
Optimized out attributes returns an invalid location `-1` resulting in
an undefined behavior shift.
|
|
|
|
|
|
The check was reversed, leading to less errors being reported.
|
|
Use using instead of typedef, remove redundant string init,
use "empty", address qualified auto, use nullptr.

Currently whenever gl queries are performed for the viewport, a large
1024 byte array is allocated to store the query results (256 of them).
Unfortunately, if any gizmo using a `draw_select` callback is active
(e.g. the transform gizmos), these queries (and allocations) will occur
during every mouse move event.
Change the vector to allow for up to 16 query results before making an
allocation. This provides enough space for every built-in gizmo except
Scale Cage (which needs 27 queries). It also removes unnecessary
allocations from two other related vectors used during query processing.

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

To avoid that, we simply filter using a debug group.

This might head lead to a crash when a shader uses both ubo and ssbo.

- Fix image.format conversion to string
- Fix warnings about ARB_conservative_depth not found even if GL > 4.2
- Add `array(type)` define for portable array definition

Thanks to the new `ShaderCreateInfo` we now include source files without
any modification. This let us query which are the source files passed to the
`print_log` function. The log will now include a file with row and column
number which is interpreted as a link in most IDE.
DEBUG_CONTEXT_LINES will add more lines around the error lines for more
context. This is also useful if the error line is imprecise (because of
driver bugs) and the reported line is not sufficient to know the location
of the error.
The DEBUG_DEPENDENCIES option will display the list of included files in
the shader sources. Note that it will not print generated source.
This commit also fixes some issues with unhelpful logs, bogus row & column
numbers, other error format, and bug if row was 0.
