Merge branch 'master' into asset-experiments

Merge branch 'master' into temp_custom_loop_normals

First use of txdata to transfer custom normals...

Had to add a pre/post process helper to txdata, since with clnors
we want to operate on regular normals data, but store results in
'compressed' clnor data.

Note things seems to be working basically, but the whole branch needs to
re-check how/when it's using (custom)lnors (same goes for master, actually!).

Border fixes

Depsgraph: Make ID nodes fully fisible by default

Depsgraph: Fix missing editors ID update callback invoke

This way tweaking node trees reflects on shading update in GLSL viewport.

Depsgraph: Add shading component and empty operation in Material node

This way we can easily define relations between material and other entities, plus
this allows to have generic recalc flush mechanism working just fine.

Depsgraph: Create ID nodes for material, so this way tag update doesn't go berserk

Without this DEG_graph_id_tag_update would consider delayed ID update is needed
after the graph is rebuilt, which is just wrong.

There are no relations fr now, need of them is still being investigated.

Remove Ptex UV attribute from Cycles

To me it seems reasonable to just use regular UV attribute, probably I
miss something important though...
