This was due to a missing endpoint case that wasn't handled in the port.
The last point still have to be discarded manually because of the
dot/stroke setting of the material.
The first test `ma1.x == -1` is not necessary anymore since the index
buffer do not contain this point (which was rendered using instance
rendering before.

Compile each static shader using shaderc to Spir-V binaries.
The main goal is to make sure that the GLSL created using ShaderCreateInfo and able to compile to Spir-V.
For the second stage a correct pipeline needs to be created and some shader would need more
adjustments (push constants size).
With this patch future changes to GLSL sources can already be checked against vulkan, without the
backend finished.
Mechanism has been tested using MacOS and MoltenVK. For other OS, we should finetune CMake
files to find the right location to shaderc.

This implements the base needed for supporting multiple view concurently
inside the same drawcall.
The view used by common macros and view related functions is indexed using
a global variable `drw_view_id` which can be set arbitrarly or read
from the `drw_ResourceID`.
This is needed for EEVEE-Next shadow but can be used for other purpose
in the future.
Note that a shader specialization is needed for it to work. `DRW_VIEW_LEN`
needs to be defined to the amount of view the shader will access.
The number of views contained in a `draw::View` is set at construction
time.
Note that the maximum number of object correctly drawn by the shaders
using multiple views will be lower than thoses who don't.
This change the attribute binding scheme to something similar to the
curves objects. Attributes are now buffer textures sampled per points.
The actual geometry is now rendered using an index buffer that avoid too
many vertex shader invocation.
Drawcall is wrapped in a DRW function to reduce complexity of future
changes.
The attribute node already allows accessing attributes associated
with objects and meshes, which allows changing the behavior of the
same material between different objects or instances. The same idea
can be extended to an even more global level of layers and scenes.
Currently view layers provide an option to replace all materials
with a different one. However, since the same material will be applied
to all objects in the layer, varying the behavior between layers while
preserving distinct materials requires duplicating objects.
Providing access to properties of layers and scenes via the attribute
node enables making materials with built-in switches or settings that
can be controlled globally at the view layer level. This is probably
most useful for complex NPR shading and compositing. Like with objects,
the node can also access built-in scene properties, like render resolution
or FOV of the active camera. Lookup is also attempted in World, similar
to how the Object mode checks the Mesh datablock.
In Cycles this mode is implemented by replacing the attribute node with
the attribute value during sync, allowing constant folding to take the
values into account. This means however that materials that use this
feature have to be re-synced upon any changes to scene, world or camera.
The Eevee version uses a new uniform buffer containing a sorted array
mapping name hashes to values, with binary search lookup. The array
is limited to 512 entries, which is effectively limitless even
considering it is shared by all materials in the scene; it is also
just 16KB of memory so no point trying to optimize further.
The buffer has to be rebuilt when new attributes are detected in a
material, so the draw engine keeps a table of recently seen attribute
names to minimize the chance of extra rebuilds mid-draw.

The CameraTexCoFactors being only valid for a single view, and being only

For the Metal shader translation support for shader-global uniforms are remapped via macro's, and in such cases where a uniform name matches a vertex attribute name, compilation errors will occur due to this injected syntax being incompatible with the immediate code.
Also adding source-level function interface alternatives where sized arrays are passed in. These are not supported directly in Metal shading language and are instead handled as pointers. These pointers require explicit address-space qualifiers in some cases, if device/constant address space memory is passed into the function.

This replaces the direct shader uniform layout declaration by a linear
search through a global buffer.
Each instance has an attribute offset inside the global buffer and an
attribute count.
This removes any padding and tighly pack all uniform attributes inside
a single buffer.
This would also remove the limit of 8 attribute but it is kept because of
compatibility with the old system that is still used by the old draw
manager.
This is a new implementation of the draw manager using modern
rendering practices and GPU driven culling.
This only ports features that are not considered deprecated or to be
removed.
The old DRW API is kept working along side this new one, and does not
interfeer with it. However this needed some more hacking inside the
draw_view_lib.glsl. At least the create info are well separated.
The reviewer might start by looking at `draw_pass_test.cc` to see the
API in usage.
Important files are `draw_pass.hh`, `draw_command.hh`,
`draw_command_shared.hh`.
In a nutshell (for a developper used to old DRW API):
- `DRWShadingGroups` are replaced by `Pass<T>::Sub`.
- Contrary to DRWShadingGroups, all commands recorded inside a pass or
sub-pass (even binds / push_constant / uniforms) will be executed in order.
- All memory is managed per object (except for Sub-Pass which are managed
by their parent pass) and not from draw manager pools. So passes "can"
potentially be recorded once and submitted multiple time (but this is
not really encouraged for now). The only implicit link is between resource
lifetime and `ResourceHandles`
- Sub passes can be any level deep.
- IMPORTANT: All state propagate from sub pass to subpass. There is no
state stack concept anymore. Ensure the correct render state is set before
drawing anything using `Pass::state_set()`.
- The drawcalls now needs a `ResourceHandle` instead of an `Object *`.
This is to remove any implicit dependency between `Pass` and `Manager`.
This was a huge problem in old implementation since the manager did not
know what to pull from the object. Now it is explicitly requested by the
engine.
- The pases need to be submitted to a `draw::Manager` instance which can
be retrieved using `DRW_manager_get()` (for now).
Internally:
- All object data are stored in contiguous storage buffers. Removing a lot
of complexity in the pass submission.
- Draw calls are sorted and visibility tested on GPU. Making more modern
culling and better instancing usage possible in the future.
- Unit Tests have been added for regression testing and avoid most API
breakage.
- `draw::View` now contains culling data for all objects in the scene
allowing caching for multiple views.
- Bounding box and sphere final setup is moved to GPU.
- Some global resources locations have been hardcoded to reduce complexity.
What is missing:
- ~~Workaround for lack of gl_BaseInstanceARB.~~ Done
- ~~Object Uniform Attributes.~~ Done (Not in this patch)
- Workaround for hardware supporting a maximum of 8 SSBO.

This new implementation does all downsampling in a single compute shader
dispatch, removing a lot of complexity from the previous recursive
downsampling.
This is heavilly inspired by the Single-Pass-Downsampler from GPUOpen:
https://github.com/GPUOpen-Effects/FidelityFX-SPD
However I do not implement all the optimization bits as they require
vulkan (GL_KHR_shader_subgroup) and is not as versatile (it is only
for HiZ).
Timers inside renderdoc report ~0.4ms of saving on a 2048*1024 render for
the whole downsampling. Note that the previous implementation only
processed 6 mips where the new one processes 8 mips.
```
EEVEE ~1.0ms
EEVEE-Next ~0.6ms
```
Padding has been bumped to be of 128px for processing 8 mips.
A new debug option has been added (debug value 2) to validate the HiZ.
These are meant to provide easy shape and AABB operation for culling.
They are currently incomplete but can be extended as one see fits.
The `common_debug_shape_lib.glsl` contains helper to draw thoses shapes.
This is a complete rewrite of the draw debug drawing module in C++.
It uses `GPUStorageBuf` to store the data to be drawn and use indirect
drawing. This makes it easier to do a mirror API for GPU shaders.
The C++ API class is exposed through `draw_debug.hh` and should be used
when possible in new code.
However, the debug drawing will not work for platform not yet supporting
`GPUStorageBuf`. Also keep in mind that this module must only be used
in debug build for performance and compatibility reasons.
The new implementation leverage compute shaders to reduce the
number of passes and complexity.
The max blur amount is now detected automatically, replacing the property
in the render panel by a simple checkbox.
The dilation algorithm has also been rewritten from scratch into a 1 pass
algorithm that does the dilation more efficiently and more precisely.
Some differences with the old implementation can be observed in areas with
complex motion.
