DPI: add back option to control line width, tweak default width.

Adds thin/default/thick modes to add -1/0/1 to the auto detected line width,
while leaving the overall UI scale unchanged.

Also tweaks the default line width threshold, so thicker lines start from
slightly high UI scales.

Differential Revision: https://developer.blender.org/D2778

Fix T52334: images with non-color data should not change color space on save.

Tweak and extend POV syntax hilghting.

*Changed categories of some keywords
*reordered some longer keywords that didn't appear
*Activated another color (reserved builtins) by Leonid
*added some HGPOV and UberPOV missing keywords

While not a regression, this is new feature and would be nice to have it
backported to final 2.79.

Fix T52324: Metaball disappears when deleting first metaball object.

Lost specific MBall 'need update' case here in last year's refactor.

While technically not a regression, nice to have in 2.79.

Fix T52315: Crash on duplicating Scene without world.

Regression from rBa7b3047cefcbf, to be backported to 2.79.

Like... seriously... :|

Fix T52280: The Image node in Compositing can't read Z buffer of openEXR in 2.79

As part of the fix for T51587, I removed the Depth output for non-Multilayer
images since it seemed weird that PNGs etc. that don't have a Z pass still get
a socket for it.
However, I forgot about non-multilayer EXRs, which are a special case that can
actually have a Z pass.

Therefore, this commit brings back the Depth output for non-multilayer images
just like it was in 2.78.

Fix fixed width box layouts

Regression, to be backported in 2.79.

Fix T52260: Blender 2.79 Objects made duplicates real still refer armature proxy.

New code was handling correctly ID's internal references to self, but
not references between 'made real' different objects...

Regression, to be backported in 2.79.

Fix width estimation for empty layouts in pie menus

Fix T52263: Crash When Splitting and Merging Areas with Header Text Set.

Not a regression, but safe enough to be included in 2.79.

Fix broken API doc generation: Partially revert rBa372638a76e0

Making those arrays static remove them from exported symbols, which
breaks API doc generation script.

To be backported to 2.79 branch.

Fix T52250: Glitch in UI in the addon panel regression

fix attempt for avoiding incorrect inner collisions between constrained objects

use exact volume calculation for convexhull and mesh when calculating masses of initial objects only

fixes for FM mesh island rigidbody path problem and volume calculation

scaling was ignored and only half of the dimensions for the volume were used, thus the calculated mass was 1/8th of the
correct mass.

fix, forgot to set angular spring stiffness and damping when converting to objects

fix for break of rigidbody behavior after 2.78c and stoptriggers are speed-dependent now

versioning fixes for angular spring stiffness / damping and exposed those to FM python api

fix for initial kinematic state after triggering and jumping back to startframe

compile fixes after merge
