Rename utility to class to be clearly a private member

Also name internal data structure ImagePreview (incase we want other kinds of previews later)

Use a resource warning

De-duplicate build-option-setting in load_kernels

Take transformation into account between the duplicator and strands
object.

The strand edit mode uses the local space of the active object, which
is the duplicator (and dupli cache owner). The strands data is in local
space of the original particle system object however, so have to
convert. This is a very hackish solution, using the first instance of
the strands data, which only works for single instance data.

remove redundant int

Refactor : Add assert and comment for clos_max

Account for d_data memory in 'get_scene_specific_mem_allocated'

Strand edit functions for storing edit data in the Cache Shape Key
modifier and editing in hair edit mode.

bpy.utils.previews api tweaks

- make BPyPreviewsCollection's annonymous
- unique id is generated automaticly
- caller store the previews in a named/meaningful location

Merge branch 'strand_editmode' into alembic

Refactor : Place output arguments at end of list and remove unused arguments

Another fix for mirror editing of strand data.

Currently strand edit mode tool use the object data 'x mirror' flag.
This flag is only available on mesh objects, but the strand editing
can be used for dupli override caches etc. as well. Eventually strand
editing should get it's own independent flag to avoid this problem.

Merge branch 'master' into asset-experiments

Merge branch 'strand_editmode' into alembic

Fix for call to mirror functions when mirroring is not enabled, giving
warnings.

Change resource management, previews now match file-io closer

Callers need to hold a reference to the preview collection and close when they're done

Comments

use easily identifiable separator for keys components

Remove redundant del statements

Avoid app._previews access via self.__class__._app

Instead import _previews globally

Also don't load bpy.utils.previews at start (now requires explicit import)
