Normal packing. The sign is stored in the A of the color buffer.
if the A == 1.0 the normal should be inverted. before use.
The reason is that packing has more precision for frontfaces, than for
backfaces
Added Object Overlap Overlay
- Added R32UI support to GPU_framebuffer
- Added R32U support to draw manager
- The overlay mode has a object data pass that will render 'needed' data to specific buffers so we can mix them together via a deferred rendering. In future will also add UV's and other data
- Overlap is implemented as an overlay so it could be used on top of the Scene lighted Solid mode (that will be rendered by Eevee.

Will be part of the collection manager where per collection the
ob->col can be set. This currently depends on DepsGraph +
CollectionManager.
I removed it for now so the code won't influence development
- added `object_color_type` where the user can set if the collection
determines the color, or the object will be used for the color.
Implemented it as an enum as later this can have a random color option.
- moved OB_LIGHTING_* to DNA_view3d_types and renamed it.
- Fixed some DRY in workbench_materials.c. Can remove more DRY's but
will need to discuss the responsibility of the workbench engine as it
might become part of the eevee renderer.
Similar materials will reuse the same shadergroup. Currently using
a custom hash function that might select too similar colors into the
same material.
Reintroduced the workbench_materials.c this file will be responsible for
material lookup/creation and shader compilation
Fixed a GPUShader mem leak
In more complex models the object color uniform data is freed before rendered.
We should copy it to local data. but for now we redirected it to a
constant.
Currently uses static lighting. Will become HDRI lighting.
Added do_versions to set default drawtype_solid and drawtype_texture to
OB_LIGHTING_STUDIO. When View3D space is created drawtype_solid and
drawtype_texture are also set to OB_LIGHTING_STUDIO.
Current studio lighting uses a dot product to simulate static lighting.
Will need to be changed in the future with different lighting models.
- added the drawtype_solid, drawtype_wireframe, drawtype_texture to
View3D
- enabled workbench panels for important render engines
- merged workbench_materials to solid_flat_mode. All draw modes will get
its own fast implementation in the workbench
