Fix recursive menus respawning on selection

Fix here is a bit hacky, we do not draw the menu and we simply await for
key release to stop the handler, or else the pie menu gets respawned
immediately.

Allow recursive menus in pies.

By returning the handler function to the general menu recursive section.
we can handle any menus that exist in the pie pieces. For now the
drag/release style pies do not work very well with this (menu is
respawned as soon as we select something in the child menu) but I hope
this can be improved further.

Minor bug fixes and several correction.

method for transforming meshes back from [-1,1] coords; sdf fields for obstacles and inflow meshes added

Fix compilation on gcc (minimalist changes, only tackled errors, not warnings).

Fixed two cases of 'code before var declarations'.
Did not touch to missing 'static' for functions, nor 'UNUSED' parameters...

rootchan variables are unused for constructing relations.

Simplified operation building: Use ID pointers and component identifiers
directly instead of passing around nodes.

This is to some degree a revert of previous changes to add such nodes
explicitly. However, it only applies to ID and component nodes, which
are really nothing more than categories (sorting operations by ID and
components).

The only exception now are the node tree build functions, which still
take a "owner_node" and need to be looked at.
