[Bf-codereview] Dupli texture coordinates for Cycles (issue 6450116)

[lukas.toenne at gmail.com]

Reviewers: bf-codereview_blender.org, brechtvl,

Description:
Reimplementation of the "from dupli" texture coordinate option in
Blender Internal texture mapping.

In this initial version it's accessible as a switch in the Texture
Coordinates node. When activated, the Generated and UV coordinates are
taken from the parent object of the instance instead, just like in the
old mapping panel. Other coordinates (Object, Normal, Reflection) are
not yet implemented, can be added later.

The UI design could be changed, perhaps this should rather be a separate
new node.
