This changes a bit how the userprefs solid lights works. They are not
visible until enabling the "Edit Solid Light" checkbox. Once enabled the
current studiolight used for solid mode will be overwritten.
Once the lighting settings are tweaked, the user can click the
"Save as Studio light" button to save the current settings.
This makes it easy to create new lighting without messing the other
presets.
The studio lights are stored as ASCII files on the disk using a dead
simple custom format.
The UI/UX is not perfect and will be improved in other commits.
Also includes:
* Separate LookDev HDRI selection from Solid Lights
* Hide LookDev HDRIs from the Solid Lights selection list
For most brushes, texture painting uses a special mask accumulation
table in order to ensure that the amount of added color only increases
when the same pixel is touched multiple times by the stroke.
Unfortunately, only the mask texture was added to the mask before
this check, while normal, stencil, texture alpha masks were applied
after this check. This means that the check can pass if e.g. the
pressure is increased, but the final mask value is actually lower.
One might think that the mask values are fixed per pixel, but with
symmetry that isn't true. The result is a nasty stripe artifact due
to the discrete cutoff nature of the accumulation test.
In order to fix this, apply all masks before accumulation.
This allows primatives to be drawn from the center using the ALT key.
Also fixes SHIFT constraint not working correctly in all directions.
Both options can be used together.

Not sure what those #ifdef's were supposed to do exactly... But one
thing is for sure, clearing that flag in particlesettings after first
encounter would prevent transferring it properly to other objects that
would use same particlesettings.
The original offset was wrong because it applied a constant to
homogenous coordinates (the actual depth is z/w), which broke
totally if near clip distance was reduced.
A correct depth offset has to take slope into account like
glPolygonOffset in order to avoid dotted lines caused by
interpolation precision variations. When drawing wire lines
however only the slope of the line itself is accessible, so
also generally increase the offset when the object is close.
Sculpt (and paint) modes rely on valid evaluated data at their initialization.
Added code to ensure that in `ED_object_mode_toggle()`, when relevant
toggle operator requires it (looks like sculpt/paint should be the only
ones affected, although particle edit may be too...).
Some space types are exposed as multiple space types,
previously the key binding to set the space type would use the last
used space-type.
Now pressing the key again cycles to the next space sub-type.
Without this, shortcut display is confusing since some space types share
a key. Keymap display will need to be updated to support this.
To make consistent with Left click select, now if click outside any point, all points are deselected.
Reduced the circle of selection to get more precission. The radius used before was too wide.
Note: There is a minimum distance to consider outside selection area.
The old onion skinning used in 2.7x has been ported and converted to 2.8. Only basic features have been included. For more advanced onion skin features, use grease pencil objects.
Onion Skin is supported in View 3D and Sequencer.
Not exactly sure why we did not have cached displist for bevel object
here... But anyway, that conversion operation should really happen
outside of depsgraph evaluation area, so makes sense to do it as when
generating geometry for rendering, imho. Also solves issues like loosing
hidden parts of the curve/surface, etc. Still using viewport resolution
for curves, though.
This is in order to have more flexible ligthing presets in the future.
The diffuse lighting from hdris was nice but lacked the corresponding
specular information. This is an attempt to make it possible to customize
the lighting and have a cheap/easy/nice-looking pseudo-PBR workflow.
* Add cheap PBR to Workbench with fresnel and better roughness support.
This improves the look of the metallic surfaces and is easier to control.
* Add ambient light to studio lights settings: just a constant color added
to the shading.
* Add Smooth option to studio lights settings: This option fakes the
effect of making the light bigger making the lighting smoother for this
light. Smoother lights gets reflected like a background hdri.
* Change default light settings to include the smooth params.
* Remove specular highlights from flat shading. (could be added back but
how do we make it good looking?)
* If specular lighting is disabled, use base color without using metallic.
* Include a lot of code simplification/cleanup/confusion fix.
The idea is to make main thread and job threads to be scheduled
on CPU dies which has direct access to memory (those are NUMA
nodes 0 and 2).
We also do this for new EPYC CPUs since their NUMA nodes 1 and 3
do have access but only to a higher range DDR slots. By preferring
nodes 0 and 2 on EPYC we make it so users with partially filled
DDR slots has fast memory access.
One thing which is not really solved yet is localization of
memory allocation: we do not guarantee that memory is allocated
on the closest to the NUMA node DDR slot and hope that memory
manager of OS is acting in favor of us.
