Needed to fix T61196, supporting clipped back-buffer in the 3D view
which is done outside the draw module.
It was also inconvenient having DRW_shader_* versions of GPU_shader_*
API calls.
- Clipping distances are now supported as a shader configuration
for builtin shaders.
- Add shader config argument when accessing builtin shaders.
- Move GPU_shader_create_from_arrays() from DRW to GPU.
* Use simple default view transform for color pickers, as Filmic does not work
well for all types of colors. We better handle this with an option and tagging
of colors as emissive or albedo like.
* For solid/workbench we also no longer use Filmic, as there is not enough contrast
and it's not really needed since this is not physically based lighting.
* For lookdev always take into account the view transform and look. Other view
settings like exposure are only taken into account if scene lighting is used,
since these are often dependent on scene light intensity.
Fixes T61022, T57649, T59363.
BF-admins agree to remove header information that isn't useful,
to reduce noise.

Developers should add non license comments as separate comment blocks.
No need for separator text.

This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
DRW_shader_get_builtin_shader can replace GPU_shader_get_builtin_shader
when we need to support clipping.
Use this for loose point & wire drawing in object mode,
clips edges in lattice edit mode.
Add 'G_draw' for all draw manager globals,
avoids adding extern to each file.
Connection between `ts` and `globals_ubo` wasn't obvious,
now called `G_draw.block` & `G_draw.block_ubo`.
Object visibility is now handled by the depsgraph iterator, but this API
was incomplete as it made no distinction for visibility of the object itself,
particles and generated instances.
The depsgraph iterator API now includes information about which part of the
object is visible, and this is used by Cycles to replace the old custom logic.
Cycles and EEVEE visibility should now be consistent, which unfortunately does
means some subtle compatibility breakage for both.
Fixes T58956, T58202, T59284.

This now only upload data per loops to the GPU, making use of index buffer
to draw polygon. This make use of the vertex cache, speed up renders
and saves a lot of vram.
Update performance is also slightly faster and can even be improved further
by updating only uvs or vcol independently.
This commits breaks texture paint batches. It will be added back in another
commit.
This makes it possible for engines to ask for batches and only fill their
data after all engine populate functions have run.
This means that, when creating the batches data we already know all the
batches that are needed for this redraw and the needed data.
This allows for less redundant data preparation and better attrib masking.
Ideally, we should run all viewports populate function before executing
the batch construction but this is not the scope of this patch.
Conversion from the old request method will be progressive and both can
coexist (see uses of mesh_create_pos_and_nor()).
This only happens after a certain wireframe threshold.
We sort triangles into 2 bins (start and end of the buffer) based on a
threshold and just draw the first bin if the wireframe slider is low enough.
This optimization is disabled for deformed meshes when playback is active.
This optimization is only implemented for meshes object for now.
This should help resolve (to some extent) T58188.
The cause is that FOREACH_OBJECT_IN_MODE_BEGIN assumed that the active
object is in the correct mode, which is wrong in this case. It also
only considered objects of the same type as active, which had to be
replaced with an explicit type parameter.
In 2.79 hiding works in paint modes with selection enabled,
so it is a missing feature. This implements it in texture
paint overlays and in workbench base shading.

Bring back per-viewport localview. This is based on Blender 2.79.
We have a limit of 16 different local view viewports.
We are using both the numpad /, as well as the regular /.
Missing features:
* Hack to make sure lights are always visible.
* Make rendered mode with external engines to support this as well
(probably just need to support this in the RNA iterators).
* Support over 16 viewports by taking existing viewports out of local view.
The code can use a cleanup pass in the future to unify the test to see
if an object is visible (or we can use TESTBASE in more places).
Now it shows more compact info below the view/object name. Render time and
memory usage is left out, as in most cases this is not so important. These
could be added back optionally if needed.
Move the weight paint drawing to the fragment shader. The shader
uses a texture that uses the U.coba_weight custom color band, or
an internal color band.
In addition to actual weights, the shader has to display two
alert colors: missing vertex group, and zero weight. The zero
weight alert has to be blended with regular weight colors,
so that a single alert vertex surrounded by weighted ones is
still visible.

We now treat Xray as being the mode where Limit selection to visible is off.
If Xray is OFF, Limit selection to visible is considered ON.
To allow 'see through wires' with solid shading (not Xray shading) we still
draw solid shading if Xray is ON with Xray Alpha set to 1.0.
This is using the existing engine (workbench forward) with 0.0 xray_alpha
and forcing wireframes on all objects.
There is no workflow/shortcut changes in this commit.
