Use a global node index assignment to enable sorted sets for nodes.

This simplifies code generation because we can use a set with efficient
lookup which also keeps a valid ordering of nodes as dictated by links.
Since any generated code uses only subsets of nodes, the ordering still
is valid for any BasicBlock.

Moved BasicBlock out of the Compiler struct.

Fix for missing stack indices in expression blocks.

When creating an expression block, the parent block stack indices must
initialize the local index map, so that external variables can be accessed.

cannot have heat, flame, fuel, react grids here

Merge branch 'master' into openvdb

Started Velvet support in viewport code.

PRB viewport : Adding lamp support and post effects. and lots of gpu stuff.
No more leaks.

Move pyrna_set_to_enum_bitmap to bpy_rna.c

Fix docstring and broken logic (inversion between key and value filtering).

Link to valid set values

Merge branch 'master' into tmp-id-users

Correction to last commit and add docstring

Add key and value type filters

allows for eg:

bpy.data.user_map(key_types={'MESH'}, value_types={'OBJECT', 'MATERIAL'})

Without this, return values could get very large.

set shards to passive if shard weight (average vertex weight) is > 0.0f instead of 0.5f, this allows to keep shards passive in case they dont get enough weightpaint (in case they are inside, and interpolation of weights is not enough)
