Cleanup: Rename graphics-lib to graphics-binding

Merge branch 'master' into soc-2019-openxr

Proper management of OpenXR graphics bindings for session setup

OpenXR needs to interface with some graphics library (OpenGL, Vulkan,
DirectX, etc.). This is done through graphics binding extensions. The
OpenXR specification requires these to be properly set up before a
session is created.

Adds the following:
* Support priority list of multiple graphics binding extensions (e.g.
check OpenGL extension availability first, DirectX on Windows second,
etc.)
* Barebones for passing graphics library data to OpenXR session
creation. This is highly system dependent, e.g. it requires GLX data
for OpenGL on X11 systems (XrGraphicsBindingOpenGLXlibKHR). More work,
including additions to GHOST, will be needed once I get to the more
graphics related stuff.
* Create an own graphics context for the VR session. It's not doing
anything useful yet. This is just to fool the Monado OpenXR runtime
so that it actually attempts to create the OpenXR session.
* Had to add two CMake modules for platform dependent #define's required
by the OpenXR specification.

Adding a new axial orientation to the blender toolbox. It allows for precise axis control of translation even when objects are parented to one another.

Merge remote-tracking branch 'origin/master' into soc-2019-npr

LANPR: Software mode now allows camera lens shift.

initial particle action abstraction

compute new positions and velocities in separate buffer

cleanup naming

ArrayRef.copy_from

LANPR: sample and batch pool goes to lanpr_share.

use NamedBuffers in more places

rename buffer accessors

rename Vec3 to float3

LANPR: hide render_buffer from SceneLANPR, implemented copy and free functions. No memory leaks on software mode now.

Merge branch 'master' into greasepencil-object

LANPR: Renoved workbench engine registeration. Now LANPR registers correctly. Memory free working.

Split profile path creation widget from colormapping code with added files

add byte attribute type
