Editmesh: report a warning when fill fails

also prevent assert with zero normal
Fix T42255: "Copy Constraints" operator has to tag the affected object
and pose for depsgraph.

Otherwise the update order can be incorrect until the next sort is
executed.
Fixed warning about redefining the __SSE__ macro in VS2013
Cycles: Add "Max Bounce" control for lamps

With this setting, we can limit the influence of a lamp to a certain amount of bounces.
0 = Only direct light contribution
1 = 1 light bounce

Correct recent refactor (use generic callback)
Gooseberry request, append the file name to autosaves as well as the pid
Slight corrections to the string formatting of autosave, thanks to
Campbell for the help!
Revert "Metastrips: disallow making a metastrip with only one strip present."

This reverts commit a1578f08dc442b0c64f05a1ab18ef0fd90a9f6e4.

Looks like some workflows benefit from being able to do this
Fix T42492, Shading error with fresnel weight node.

Orthographic case needs different handling.
Editmesh: select more/less can now step over adjacent faces

This keeps a square shaped selection when using grid topology.
Fix T42525 crash when deleting lamp attached to Lamp Data material node
in material shading mode.
Fix T42497: Enlarge rename text field in File Browser

To ensure there's space for more than a few characters in the rename text fields of the File Browser, we now use a width relative to the column width (for all display modes).

Includes some edits from @campbellbarton - thanks for this!
better fix for fix T42525 (tm)

Looks like material node trees are stored directly in the material. The
reason I thought this was fixed was because my test file didn't connect
the lamp data node in the rest of the tree.

Thanks to Campbell for catching this :)
Fix T42208 color pickers are coupled.

Decouple color picker hsv data from the whole block. Basically, each
color picker now takes care of creating its own color picker role. For
this bug report it can be seen that probably HSV is not the best space
for gamma/lift/gain workflow because it is bounded at 1.0 but this is a
separate issue.
Fix assert failure in GPU codegen

Even though GLSL allows to have polymorphic functions our codegen
is not aware of this at all.

Let's rename the functions for now, but in the future would be handy
to make codegen aware of the polymorphic functions.
Cycles: Tweak to the expf() speed workaround

Add compile-time check for particular glibc version which fixed the issue.
This makes it so own-compiled blender is the fastest in the world, and the
only issue remains what should we do for release builds.

After some discussion with Campbell we decided to keep it as is for now
because slowdown is not that much noticeable. We'll disable this workaround
for release builds when all the majority of the distros will switch to the
new version of glibc.
Fix T42531: Setting 'Undo' steps to '1' causes weirdness.

Do not allow '1' value here, it's useless.

Thanks to Campbell for suggested solution here!
cmake buildfiles Cleanup / Refactor, no functional changes.
Move away from using hardcoded ${target} when calling install() in cmake
Cleanup: cycles whitespace
Add safe_normalize to cycles, avoid checking length first

This won't give any big speedup,
just avoids redundant sqrtf and may be useful in future.
