This forces the full geometry when that overlay is enabled.
I would rather not support this and leave that bug as a know issues/
limitation because this is terrible for performance and people may not
be aware that by enabling the option they are disabling the
optimization.

Don't use BKE_view_layer_context_active_PLACEHOLDER which is marked
as "never use this".
In fact, it isn't needed to lookup for camera in the tracking function
at all: camera object is always explicitly passed to it.
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.
Only Metaballs are left unsupported.
However, the implementation does not match 100% with cycles which converts
all objects to meshes.
Fixes T63424 EEVEE: Normal map node doesn't works with curve objects
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.

Try to never do operation twice and try to use MADD operations. Even if this
is very unlikely to make any difference, it can help compilers do some
optimization. I did not measure any difference as probes have much higher
impact on render time because of texture lookups.
Note that disk light is currently the most expensive light type so it
does not hurt to micro optimize.
This was due to the fact the drawing code was expecting the editpoints
to be equaly spaced. Reuse the code in particle.c to output the select
mask in red color channel of the particle (which is unused in new code).
Instead of changing the modifiers behavior, we make sure to always use
the data->totcol instead of the ob->totcol. Also we centralize getting
this number to avoid future issues.
