This commit adds a sample-based profiler that runs during CPU rendering and collects statistics on time spent in different parts of the kernel (ray intersection, shader evaluation etc.) as well as time spent per material and object.
The results are currently not exposed in the user interface or per Python yet, to see the stats on the console pass the "--cycles-print-stats" argument to Cycles (e.g. "./blender -- --cycles-print-stats").
Unfortunately, there is no clear way to extend this functionality to CUDA or OpenCL, so it is CPU-only for now.

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.
Meshes from evaluated objects may already have modifiers applied, but
that's not the case for curves, we need to do that when converting them
to meshes.
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.
See T57857 for discussion. This reverts:

Tools can define a function that generates the tooltip using a function,
this takes the tools keymap as an argument which can be used
to extract keys to include in the tip.
A few reasons motivating this change:
* It works well for all devices: mouse, trackpad, and tablet pens.
* For beginners or users coming from other software, it's easier to get
started and avoids an initial stumbling block.
* Many users in 2.7 (about half?) were already using left click select, so
combined with the above advantages it makes for a practical default.
Note that we continue to support right click select, as many experienced
Blender users (and developers) see efficiency advantages in this approach.
The option to switch is in the first time setup splash screen, and in the
user preferences.
Curve/surface/text final data may be an evaluated mesh instead of a
displist, when some modifiers (constructive ones in particular) are
applied to it.
Note that this is just getting feet wet, whole draw code suffers from
the same issue! :P
