Use the geometry subtree in object nodes rather than the toplevel node tree.

This is currently a hack, since only a single geotree is used. Eventually
all geometry subtree result should just be combined.

Removed unused code.

Cleanup: De-duplicate multi-sample handling

Merge branch 'master' into id-remap

Always draw face map widgets using backface culling

Also minor cleanup.

Draw bone colors for face map widgets with transparency

Merge branch 'master' into wiggly-widgets

Added a 'PASS_MESH' node.

Make an extra copy of the resulting node DM after eval.

This is necessary unfortunately because of the unreliable nature of dm->needsFree.
Without it the BKE_object_free_derived_caches function can destroy our static
empty DM at any point.

Added an assertion to make sure we don't add invalid node instances with unknown types.

Added a graphviz debug dump function for the object modifier node tree.

Use the default output value for graph returns in case they remain unlinked.

In case of meshes this will always be an empty mesh, but it at least gives a valid return value.

Foundations for a mesh data type in bvm

Mesh type for storing DerivedMesh as a temporary storage on the node eval stack.

Use a full TypeDesc in node sockets.

For the time being this is synonymous with the base type, but in future
it could allow (fixed-size) arrays and vector semantics.

Set of basic node classes for representing modifiers in pynodes.

Simple integration of object nodes into the modifier stack evaluation.

Fix: Transforming GP Keyframes in DopeSheet was no longer possible when in EditMode

This was a consequence of the hack used to ensure that the jump keyframes operator
could correctly use GP keyframes when in the timeline and action editors.

Fix: GPencil snap cursor to selected wasn't working

Min-max weren't getting initialised correctly, causing this to fail.
