Implementation of OpenVDB as a possible cache format for smoke
simulations.

This commits implements OpenVDB as an extra cache format in the Point
Cache system for smoke simulations. Compilation with the library is
turned off by default for now, and shall be enabled when the library is
present.

A documentation of its doings is available here: http://
wiki.blender.org/index.php/User:Kevindietrich/OpenVDBSmokeExport.

A guide to compile OpenVDB can be found here (Linux): http://

OpenGL: combine multiple GL_LINES into fewer draw calls

Incidentally, one of the removed glBegin(GL_LINE) calls should?ve used
GL_LINES with an S, which was a GL_INVALID_ENUM error.

OpenGL: tiny state-change fix

Only re-enable blending if the function that disables it was actually
called.

Still not ideal flipping this on & off repeatedly, but now there are
fewer flips.

OpenGL: call glLineWidth less often

Each LINES draw call is now responsible for its own line width. No need
to set it back to its 1.0 default after every draw.

This eliminates half our calls to glLineWidth , similar to last week?s
work on glPointSize.

Math Lib: optimize segment-plane clipping

Calculate the clipped min/max factor along the segment,
only applying to the coordinates at the end (will give better precision too).

Also make split input/output args.

Cycles: Change several default values (first batch).

This changes the following defaults:

- Render settings:

* Samples: 100
* Preview Samples: 50
* Filter: Blackmann-Harris
* Tile Order: Hilbert Spiral

- Lamp settings:

* Use MIS: On

- Material settings:

* Volume Sampling: Multiple Importance

Old files are not affected, I tested the versioning code back and forth.
More changes are to come (World, BVH...) but that needs a bit more work.

Fix part of T47025: Shadow pass error: Black shadow.

Skipping computing of shadow pass when diffuse color is pitch black is fine... unless
you actually need/want that shadow pass!

The 'noisy' issue with picture texture remains a bit mysterious to me currently. :/

Fix T45523: "View All" in Graph Editor does not respect Y axis with small values

The previous threshold used to prevent the Graph Editor from imploding if
presented with a flat (or nearly flat, accounting for floating point precision)
curve was too coarse, meaning that in some cases, the "View All" tool would end
up behaving weirdly.

Dopesheet: Make frame range for new editor instances saner, by basing them on the current frame range

This brings the dopesheet more in line with the NLA and Graph Editors, where
similar initial ranges were also used. The benefit is that it should save
animators a small amount of time getting the dopesheet timeline into the
right zoom level before starting work.

Fix T46657: VSE: Strip length jumps to a negative number.

OpenGL: cleanup

- LINE_STRIP to LINES when only drawing one
- group state changes for easier reading
- general cleanup

OpenGL: remove unneeded state changes

UI_panel_category_draw_all was setting PolygonMode to LINES before
drawing LINES.

stitch_draw was setting PolygonMode to its default FILL value ? any
function that deviates from the default should?ve changed it back to
FILL.

OpenGL: draw box outlines with lines, not rectangles

2 reasons:
- fewer state changes (PolygonMode)
- glRect goes away in later GL versions

OpenGL: remove glGet with unused result

This code is disabled but still?

OpenGL: remove extra vertex in arrowhead

Now draws 2 lines instead of 3 (with a zero-length middle).
Same visual result.

OpenGL: pull glBegin/End out of loops

When drawing 2D grid and 3D axes.

GPencil: Select Grouped (Shift G)

This commit adds a "Select Grouped" operator. Although it is set up to
allow more types of "grouping" in future, it current only supports
a single mode (i.e. "Same Layer"). As a result, it does not pop up
any menus/submenus in all the usual places.

OpenGL: fewer state changes for wireframe PBVH

Wireframe drawing doesn?t use the following GL state, so don?t update
these:
- ShadeModel
- NormalPointer
- ColorPointer

Normal & color data are still uploaded as part of the interleaved VBO,
but those attributes are disabled for wireframe.
