a704a66914 Adding some verbose documentation 
I thought this was already clear enough, but apparently not.

f2b3e1f712 Eevee: Fix T52480: Can't reproduce Metallic transparency with Principled + Mix Shader 
You can now use a transparent shader as a completly transparent bsdf. And use whatever alpha mask in a mix shader between a transparent bsdf and another bsdf.

4aee701f00 Fix T52679: Hole in bake normal 
In fact, any type of baking might have caused holes in mesh.

The issue was caused by zspan_scanconvert() attempting to get order of traversal
'a-priori', which might have failed if check happens at the "tip" of span where
`zspan->span1[sn1] == zspan->span2[sn1]`.

Didn't see anything bad on making it a check when iterating over scanlines and
pick minimal span based on current scanline. It's slower, but unlikely to cause
measurable difference. Quality should stay the same unless i'm missing something.

74eed8e30e Fix T52705: Lamps shadows are not refreshed when tweaking lamps parameters 
Lamp and camera datablocks updates should flush some updates to corresponding
objects. Currently it's done as Parameters -> Parameters relations.

d126ffbea4 DRW: Use static list (array) of texture/ubo to track bound textures/ubos. 
This is in order to use the same texture on multiple sampler.
Also texture counter is reset after each shading group. This mimics the previous behaviour.

35ee9ff7a0 Fix T52682: When hair number=faces number, particles/face = 1 , actually some hair is overlap. 
Just using same code for distribution for face/volume as the one
changed/used for vertices since some months.

Note that this change is breacking compatibility, in that distribution
of particles over faces/volume may not be exactly the same as
previously.

9fdf094b85 Eevee: Shadows: Filtering improvement. 
- Replace poisson by concentric samples: Less variance. They are sorted by radius then by angle.
- Separate filtering into 2 blur. First blur is 3x3 box blur. Second is user dependant.
- Group fetches by group of 4.

716f7859a8 Eevee: Add Cascaded Shadow Map support with filtering. 
This brings some data structure changes.
Shared shadow data are stored in ShadowData (in glsl) (aka EEVEE_Shadow in C).
This structure contains the array indices of the first shadow element of this shadow "object".
It also contains how many shadow to evaluate (to be used for Multiple shadow maps).

The filtering is noisy and needs improvement.

- Use only one 2d texture array to store all shadowmaps.
- Allow to change shadow maps resolution.
- Do not output radial distance when rendering shadowmaps. This will allow fast rendering of shadowmaps when we will drop the use of geometry shaders.

- Use indices instead of character args.
- Use numbered macros instead of variadic args.

Parsing using rtags used over 11gb of memory. While this should be
resolved upstream (report as #1053), the extra complexity didn't give
any real advantage.
