Cycles: Correction to previous commit -- forgot to take instancing into account
Correct own regression in password button editing

Fix T41416: by iri Hnidek
UI: Don't print user passwords in info-space
Revert modal operation of cursor. This change was far less innocent than
was first thought and could mess up tweaking events for the left mouse.
Attempt to fix 32bit OSX buildbot, need to link against UTF Collada lib
Fix part of T41297.

Add precision mode to radial operator by keeping the shift key pressed.
Precision mode works by checking difference between absolute window
coordinates and the point where shift was pressed and adding those to
the distance between that point and the radial center. This allows
bigger negative/positive range than using a strict radial scheme.
OSX/Scons: make sure BF_OSL implies BF_LLVM
OSX/SCONS/buildbot: last commit made BF_COLLADA_LIB tweak obsolete
Fix crash on texture painting after new scene is added, reported by
kopias on irc, thanks.
Deactivate last active button for pie menu popups.
Last fix wasn't complete, sorry for that..
Aaaarh! aaargh!
Pie menus:

If user drags away from initial position, menu changes to drag style and
returning to that position won't remake the menu click-style. Allows to
use the threshold indicator to cancel the pie.
Cycles: Avoid segment NULL check, we access it before this function already.
Cycles: Avoid intermediate function when we sample all lamps.
Switch sampler icon to the right, it's easier for artists to access.
Cleanup: typos and extra brackets.
Cycles: Optimization for Heterogeneous Volume Shadows.

* Don't compute expf() for every step, instead sum the intermediate values and calculate it every N (8 for now) steps. This helps a few percent (~5% on a cube with wave texture) in my tests here.
Cycles: Optimize Equi-Angular sampling using binary range search.

Patch by Lukas Tönne and myself.
Fix 'quick smoke' not rendering anything (texture coordinates was left unset)

Not quite sure why default did not work here, might need further investigation.
