Since rB2a7a01b339ad, `lineSmooth` has lost its default value of true.
So set the value when creating the shader.

This should have no functional changes.
This reduce the complexity of the shader by only supporting 2 colors.
We never use more than 2 color in practice and this makes usage not require
a UBO.
Since shader sources are now parsed on demand via `GPUShaderCreateInfo`,
sources are not available to be read via
`GPU_shader_get_builtin_shader_code`.
Currently this results in a crash as the code tries to read `NULL`
pointers.
`GPU_shader_get_builtin_shader_code` was created with the intention of
informing the user how a builtin shader works, thus "replacing"
detailed documentation.
Therefore this function doesn't really have a practical use in an addon.
So, instead of updating the function (which would require several
changes to the gpu module), remove it and improve the documentation.

This shader needs to use the same interface as the OCIO shader. On Linux
and Windows this seems to be the case. On MacOS however there is a
mismatch that makes the overlay texture to be completely black when
switching to workbench in the Shader workspace.
This is just a temporarily work-around as this should be solved. Due to
the poor GPU debugging facilities on Mac we haven't been able to
pin-point the root cause.
This patch converts GPU_SHADER_2D_IMAGE_MULTI_RECT_COLOR shader to use
the GPUShaderCreateInfo pattern. It can be used as a reference when
converting other shaders.
In this special case the flat uniform vector cannot be used anymore as it
doesn't fit as push constants. To solve this a uniform buffer is used.
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.

Issue introduced in {7e66616b7e15} where the shader was replaced with a
2d image shader. This patch reverts several commits that removed the 3d
image shader.
No functional change.
The shader is complicated by itself, having hardcoded values makes it
even more cryptic.
I also renamed the shader because the shader is not for the keyfarme diamond only,
but for all the keyframe shapes.

This follows the GPU module naming of other buffers.
We pass name to distinguish each GPUUniformBuf in debug mode.
Also remove DRW_uniform_buffer interface.
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`.
