Cleanup: reorder logic of read_mesh_sample.

Moved some code around. Got brush strength working.

Fix vertex colors read/write.

Fixed a bug where some vertices under the brush wouldn't paint.

cleanup in manta export. obj file export is not needed anymore

De-duplicate cache file loading logic.

Fix compile error (from change in master).

Merge branch 'master' into soc-2016-pbvh-painting

Fixed memory leak on map.

Fix graph return values: Not all value types are returned as duals.

Merge branch 'master' into alembic_basic_io

Cleanup: use normal_short_to_float_v3.

Split curves reader/writer in a separate file.

Fix for graph function signature: use pointers also for aggregate and struct types.

Initial support to export curves.

finish the rough pipeline, begin debugging

Use the LLVM backend for modifier nodes.

This currently fails, because the actual mesh nodes are not yet implemented
in the LLVM backend.

Reduce repetitive code in the C API by defining static node graph signatures.

Node graph inputs/outputs are now defined statically and graph instances
can be constructed by passing these as ArrayRefs. The code for compiling
various node graph types can then be unified.
