Fix T44137: bpy.path.is_subdir fails

`bpy.path.is_subdir("/abc/def/ghi","/abc/de")` incorrectly returned True

Fix: AUD_OpenALDevice::getPosition returns negative values

Reported by Antony Riakiotakis. The problem was the seeking code.

A more forward thinking version of previous commit

Basically same as 581afa9da37, but I guess we can assume that scopes added in future
to the image preview may also want to use the viewrect from the original ibuf.

Fix T44121: VSE Preview scaling issue when using proxies and Show Overexposed

Yet another fix for crashing particles.

minor cleanup: alignment

Fix T43694, by Krzysztof Re�?ko (chrisr), reviewed in D1177.

Added some guards to prevent clumping to non existing particles. Also, adjusted threaded child path evaluation, so each child is evaluated once - previously virtual parents were done twice.

Fix 2 typos ( shakin' hands )

Fix T44133 SSAO in OpenGL rendering from orthographic camera did not
work

Safe to include in final release

Fix crash with computers not supporting high quality depth of field.

Fix T44026: ID prop delete leaves names in _RNA_UI

Attempt to fix an error in compilation of geometry shaders in Intel 4000
cards (see T44072)

use BKE_mball_tessellate.h include

also remove unused includes

BKE_mball: split tessellation into its own file

this has a lot of its own local structs, functions,
better to keep isolated from general metaball selection/library logic.

Change Enables proxy operator to Copy proxy operator.

Allows to change and copy settings much easier, also allows things like
directory settings etc to be copied over.

Fix for crash when using particle emission with clump/roughness curves
in a smoke sim.

This interaction between sims is totally stupid and must be recoded
entirely in some utopian future.

Allow multiple strips to use the same directory when custom proxy
directory is used.

This is done by appending the name of the file as extra folder. Existing
projects may need to regenerate their proxies but it should be possible
now to have all proxies nicely in the same custom folder.

Next commits will include operators to copy directory settings between
selected strips, making the process faster.

Fix T44128: Ray visibility only enables diffuse if glossy is also enabled

Issue was caused by accident in c8a9a56 which not only disabled glossy
reflection if Glossy visibility is disabled, but also Diffuse reflection.

Quite safe and should go to final release branch.
