The conservative depth shader is ~4.5x slower than the normal one as it
uses geometry shader and fragment shader discard.
This patch also includes a hack to also fix the view parallel planar
geometry and the really small wire objects.
For some reason, the conservative raster fix does not work with normal
selection but does with box select.
This is a fix for T63356.

When using duplicate linked meshes, objects that are not in edit-mode will be drawn as
it is in edit mode, when another object with the same mesh is in edit mode.
This will not be the case when one of the objects are influenced by modifiers. The change
reflects more how it was done in Blender 2.79.
The current change introduces a draw manager method that checks in detail who is responsible
for the drawing (render engine or overlay engine). If the edit mesh is not the original or
the object that is drawn doesn't draw the original mesh the object will be drawn by the render
engine.
Known Limitation of this patch is that the rendering outside edit mode doesn't reflect the
latest changes until the user switches between object and edit mode. When there are no
modifiers in use, the updating is done immediately.
IMO this would be sufficient for blender 2.82, it also fixes parts of T72733.
The updating of the surface batches requires more development and is
post-poned for now.

This moves the backface culling to the fragment shader to avoid all the
limitations of the current system. This has a cost but it is unlikely that
bone drawing will be a bottleneck.
In blender 2.79 you could use a render result as a camera background
image. This is useful during layout/compositing. During Blender 2.80
development there were 2 issues introduced that removed this feature.
* to receive a render result the image required a lock. This lock wasn't passed and therefore no image was read from the result. Generating an GPUTexture from an Blender image also didn't do the locking.
* the iuser->scene field wasn't set what is required for render results.
This change adds an optional `ibuf` parameter to `GPU_texture_from_blender` that can be passed when available.

I doubt we can do much better. Most of the aliasing comes from the edge
detection which does not use a lot of samples. We could use more samples
but then the detection becomes way more complex and expensive.
The second issue comes from the reconstruction (AA pass) that only bleed
adjacent pixels in if their line direction is perpendicular to the offset.
This makes corner gaps on certain diagonals.
We can't use the fast path when the mesh is used by mulitple objects and so
slower sculpting is expected then. But fake users should not affect this. This
also fixes the same type of error in a few other areas.
Blender supports locking vertex groups to prevent changes to the
weights. However, as mentioned in comments for D3837, it is hard
to use this because there is no interface for locking in 3D View.
This adds a red shade to bones that are associated with a locked
weight group during weight paint mode, as the first step to adding
such interface. The next step is adding a pie menu for lock/unlock.

When in sculptmode the wireframe coloring should always be disabled.
When an object was sculpted but had modifiers this was not detected and
the colors were still shown.
This fix will disable wireframe coloring for any object that is in
sculptmode.
Vertex colors behaved differently as the paint overlay mixed the colors
in display mode and the results was multiplied on top of the original
shading.
This patch will align the implementation to texture painting where the
colors are drawn by the workbench engine so the correct shading is
applied.
This also means that we don't show the vertex colors overlay when not
in solid mode.

Due to recent refactoring of the overlay unification the camera limits
were also visible when the overlays were turned off. This was because
the `draw_extra` had an exception for when looking through the camera.
This change also takes the global hide overlays into account. So now the
camera limits will not be drawn when overlays are turned off. This also
fixed other camera related overlay drawing.

Viewport: Disable Clipping For EEVEE and External Renderers
Currently it is possible that, when using viewport clipping, the display and tools communicate
different information to the user then the renderer does. The reason is
that the renderer does not support viewport clipping. Both EEVEE and
Cycles do not support it.
This patch will disable the clipping in all the tools and drawing code
when the viewport drawing mode is `Material Preview` or `Rendered`.
This patch introduces a `RV3D_CLIPPING_ENABLED` util that checks if
clipping is enabled for the given `rv3d` and `v3d`. Also in places where
it was needed we added the `ViewContext` as a carrier for the `View3D`
and `RegionView3D`.
There are a few areas in the tooling (select, projection painting) that
still needs to be tackled after this patch.

Multisample buffers were used for smooth line drawing. As we now have
an algorithm that doesn't need the multisample buffers we can remove
them.
The user preference for viewport multi_sampling is replaced by single
toggle overlay `use_overlay_smooth_wire`. By default this setting is
enabled as the new drawing is really quick (<1ms) and uses zero hacks.

The Camera Background Images uses a alpha under blending. For alpha
under blending to work correctly the framebuffer containing the result
of the render engine needs to be active
(`DefaultFramebufferList.default_fb`) and the source blend color needs
to be premultiplied with alpha.
Due to recent refactoring this wasn't the case and it seemed that the
background image was drawn in front of the scene. This patch sets the
correct state so it seems to be drawn behind the scene.
