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.

This patch will apply the view transform when a movie clip is used as
camera background image. It does this by rendering the image in the
color buffer when it needs the view transform. For other images it uses
the overlay buffer.

The underlying type of the enum cannot be fixed here due to its usage
in C code.
All the values possible in the width of the underlying type are not
valid for an enum.
Only 0 to (2*max - 1) if all enumerators are unsigned.
So the macro asks for the biggest value among the //listed// ones.
If any enumerator C is set to say `A|B`, then C would be the maximum.
(2*max-1) is used as the mask.
The warnings (for each enum modified in this commit):
GPU_vertex_buffer.h:43:1: runtime error: load of value 4294967291
which is not a valid value for type 'GPUVertBufStatus'

This directly adress the issues caused by rB536c2e0ec916.
Since the state tracking is done at a lower level, using the bgl
functions needs to be safegarded by the state manager.
The current workaround is to bypass `apply_state` when inside a
callback that used a `bgl` function.
Related to T80730.
This fix T81003.
Also this fix the default blend equation for callbacks.
Fixes T80169 T81289.
This makes wide line supported on MacOS and other implementation that
does not support wide line by default.
This workaround works for all Line types but only if using one of the 5
default shaders.
The workaround is completely isolated and invisible to the outside. It has
no side effect.
Note: This does not affect the GPUBatch drawing.
This was caused by a missing state apply.
We force the GPUState to be set after the callbacks to avoid
desync between our state tracker and the real gl state.
This fixes some issues but a better general fix for all BGL would
be better.
This fix T80297 2.91 texture alpha is not transparent
This wraps the functionality used to speedup EEVEE volumetrics.
This touches the rendering code of EEVEE as it should fix a mis-usage of
the GL barrier. The barrier changed type and location, removing an
unused barrier.
In recent refactoring {a9f2ebb21508} an issue was introduced that the
opengl rasterizer would be disabled when only writing to a stencil
buffer.
This fix adds stencil writing to the write mask and set it. This makes
the write map not evaluate to GPU_WRITE_NONE and the rasterizer will be
enabled in `GLStateManager::set_write_mask`.

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

This is in order to disolve GPU_draw.h into more meaningful code blocks.
All the Image related function are in `image_gpu.c`.
All the MovieClip related function are in `movieclip.c`.
The IMB module now has a connection with GPU. This is not strickly
necessary and the code could be move to `image_gpu.c` if needed.
The Image garbage collection is also ported to `image_gpu.c`.
Also put glDisable(GL_DITHER) in it since we don't even use it (but is
enabled by default).
Also leave GL_MULTISAMPLE on by default since it has no impact on non-MSAA
framebuffers.
- Move gpuPush/Pop from GPU_draw.h into GPU_state.h
as this is for pushing/popping state.
- Add 'GPU_STANDALONE' define, to bypass use of user-preferences
for theme colors and pixelsize, as well as pbvh init/free functions.
Needed to get GHOST tests working again.
BF-admins agree to remove header information that isn't useful,
to reduce noise.
