In final rendering mode the display type was tested for
visibility flag. This should only occus when doing viewport
rendering

This makes it easier to exclude a surface from casting shadows and can be
used to manipulate the shadows even for opaque surfaces.
Versionning ensure that old behavior is transfered to new rendering logic.
Draw manager was checking for particles being enabled in viewport, but
actual evaluation was happening for render. Now the check in draw manager
properly follows current evaluation mode.
Additionally, de-duplicated some check, by moving everything needed to
a single place.
Annoying part is the const-cast, that could be cleaned up later by
modifying some underlying functions.
This was due to environement not being rendered with alpha blending. So
color was still written and contributed to the final render color. Now
we multiply by background alpha so that it removes any background pixels
intensity.
For this reason this made the (incorrect) final premult unecessary.
Main change are:
- the fresnel LUT is separated from the main GGX LUT.
- LUTs use sqrt(1.0 - NV) as roughness remapping. Improving precision and
removes needs for acos().
- LTC LUT is normalized by matrix middle component. Improving precision.
BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
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This is often invalid, outdated or misleading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.
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`.
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.
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.

The crash only occurs with Intel 3rd generation GPUs.
It occurs because the program needs to be used at least once in the opengl context in which it is created.
This is a nasty bug. Because the node does not get properlly tagged as SSS
(sss_id is 0) but is still evaluated (so tagging the GPUMaterial as having
SSS). The sssProfile UBO is still declared and we need to bind something
to it.
This is more like a static optimisation when some parameters are set to 1.0
or 0.0. In theses case we use a more optimized version of the node.
This also revisit the transmission parameter behaviour to make it closer to
cycles.
Some of them are unecessary and should be removed from the shader instead.
But for now we need a quick fix for the crashes happening on some platforms.
See T55475.
