This mean we can now have different shadow resolutions for both.
However each shadow type keep the same size accross all lamps because of
future "real" Cube Shadowmaps limitation and to save texture sampler slots.
That said the cascade shadow resolution could (in the future) still be
changed to be adjustable per sun lamp.
Existing code checked pose/edit mode to check for transforming in an
objects local space.
This added many similar checks all over the code,
which leads to confusion.
Multi-edit caused a regression in UV transform since where UV's
had the object matrix applied by accident.
Now there is a boolean to use a local matrix,
this allows for any mode to have a 4x4 matrix
applied w/o adding mode specific checks everywhere.
Initial review of the shard shadows in the workbench engine.
Speed optimizations like transform feedback are not implemented yet. I first want this part to be reviewed and merged.
@fclem please check the note in drw_stencil_set it was holding back nequal == 0 as by default DST.stencil_mask was set to 0. questioin is should we remove the whole check or not.
Also I am still looking for a better name (or split the enum) for DRW_STATE_STENCIL_DEPTH_FAIL_INCR_DECR_WRAP

Those should be used in priority when you need to create either a new
datablock in Main, or a new temp one. Lower level BKE_libblock_...
should only be used when you need a very specific, uncommon behavior.
The value of epsilon was never used to create this bvhtree because whenever we activate this constraint, a bvhtree with parameter epsilon 0.0 was created and cached.
Seems to be only related on linked nature of particles.
This is caused by some conflicting optimization done for viewport, which
does not do particles re-calculation if they do not depend on time
(which is crucial for big layout scene grass fields) and particle render
setting switch which was relying on fact that render pipeline will do
particle update via time dependency.
Now we extent an old workaround for invisible objects, which now also
deals with particles in the same way as old dependency graph was dealing
with this: tag object data for update if there is particle system.
There shouldn't be any speed difference between old and new depsgraph,
since tagging was already needed and was happening.
In Blender 2.8 such things should be easier to deal with since the whole
depsgraph is to be evaluated for render engine anyway.
`MREMAP_RAYCAST_APPROXIMATE_BVHEPSILON(ray_radius)` greatly increased the radius making for example that 0.1 becoming 1.5
Now the result is much more predictable.
