Fix compositor node links getting lost on file load for custom render passes.

Fix T52514: don't clear filename when dropping directory path in file browser.

Fix T52998: disabled menu entries responding to key shortcuts.

Fix T52800: fix UI flickering with Mesa on Linux.

Use triple buffer by default now on all platforms, remaing ones where:
* Mesa: seems to have been working well for a long time now, and not using
it gives issues with the latest Mesa 17.2.0.
* Windows software OpenGL: no longer supported since OpenGL 2.1 requirement
was introduced.
* OS X with thousands of colors: this option was removed in OS X 10.6, and
that's our minimum requirement.

Fix potential string buffer overruns.

Note that our library path handling is still rather dodgy on this
regards, shall take some time at some point to seriously sanitize it...

Fix T53002: Batch-Generate Previews generate empty or none image for large objects.

Camera clipping was left to default values, which won't work well for
very large (or small) objects. Now recompute valid clipping start/end
based on boundingbox of rendered data, and final location of camera.

Fix missing ID remapping in Action editor callback.

Spotted by Joshua Leung (@aligorith), thanks!

Should probably be backported to 2.79a should we do it.

Fix T52816: regression can't open file in 2.79 (crash).

Tentative fix, since I cannot reproduce thenissue for some reason here
on linux.

Core of the problem is pretty clear though, thanks to Germano Cavalcante
(@mano-wii): another thread could try to use looptris data after worker
one had allocated it, but before it had actually computed looptris.

So now, we use a temp 'wip' pointer to store looptris being computed
(since this is protected by a mutex, other threads will have to wait on
it, no possibility for them to double-compute the looptris here).

This should probably be backported to 2.79a if done.

Add some security checks against future bad float UIprecision values.

This commit and previous one should be backported to 2.79a should we
release it.

Fix (irc-reported by @sergey) invalid precision value in a float RNA property.

Maximum allowed UI float precision value is 6 (which means 7 digits).

Will change code checking on that in next commit.

Fix T52729: Decimals not showing over 100m or 100 feet

Use same 5 digits precision as we already use for e.g. Object's
location, for Object's dimensions too.

To be backported to 2.79a, should we do it.

Fix failure in our UI code that could allow search button without search callbacks, leading to crash.

Related to (exposed by) T52735, fixes the reported crash but not the
underlying issue.

To be backported to 2.79a should we do one.

Fix T52984. Trackpad rotation to natural direction

acceleration maps are kinda hard to get right... another attempt

fix, possibly return an empty mesh and default psys index is 1 now

fix for randomized particle sizes

was accessing wrong indexes after particles died

added override with particle size option to mball remesher

remesh modifier can now remesh particle systems as well

small fixes for acceleration map

refactored acceleration map, but might still have issues

also attempted to improve triggering (make exacter, but slow and error prone)
