Fix #33486: cycles CPU image textures were offset wrong by half a pixel compared
to OpenGL/CUDA/OSL rendering.

fix for EDBM_index_arrays_ensure not working as intended.

add threshold for bmesh & openmp so its not used with low poly meshes, BM_OMP_LIMIT may need tweaking.

add destructive argument to bmesh.update_edit_mesh()

make EDBM_index_arrays's stay in memory, blender was allocating an array and filling it for verts/edges/faces on every redraw.

this may introduce bugs which I didn't catch, but they are very easy to identify in a debug build which has asserts to ensure the arrays are valid before use.

in my own test drawing ~98,304 quads - this gave an overall ~16% drawing speedup.

Fix #33485: cycles OSL now autodetects the presence of emission and transparent
closures to enable multiple importance sampling and transparent shadows.

use htype flags as arguments to EDBM_index_arrays_init(), no functional changes.

use openmp to thread some common bmesh operations
- BM_mesh_elem_toolflags_ensure / bmo_flag_layer_alloc / bmo_flag_layer_free / bmo_flag_layer_clear
- BM_mesh_select_flush
- EDBM_index_arrays_init

notes:
- mostly use openmp `sections` to split operations on vert/edge/face since this is a fairly minor change.
- split tool flag pool in 3, this means we can allocate exact sizes needed and iterate on them in threads without alloc'ing.

assert in debug builds if MEM_ alloc's are called in openmp threads.
note: the caller can do locking to prevent errors - but this isn't being done in blender yet, so this prevents accidental allocs in openmp for now.

replace BLI_array_declare with BLI_array_staticdeclare() and BLI_array_alloca() for smaller arrays.

Further fix for svn:executable.

Fix for svn:executable.
Reported by Bastien Montagne, thanks!

A big cleaning patch by Bastien Montagne (thanks a lot!)

* Split and moved Cycles�?? render layers panels into the render_layer
context as well (would be nice to hide this context when not needed,
e.g. with the BGE, but this is not so easy to do nicely...).

* Fixed some inconsistencies with trunk (probably due to svn merge
glitches) using r52858 as reference. Also recovered the missing
release/bin/blender-softwaregl file.

* A bunch of style code fixes in Blender's own code (not Freestyle
itself yet): line lengths, spaces around operators, block formatting,
headers, etc. In rna_linestyle.c, color_blend_items was replaced by
ramp_blend_items (exported from rna_material.c).

Fix for cloth/smoke: Collision and flow objects always had to be on the same layer.

Reported and patch by MiikaH

Install dependencies used to always mark schro as used for suse.
Now it should respect all features option.

Also removed some duplicated entries.

OSL Shader Files:
* Simplify default color values, where each component was the same.
* Initialize closures as Null Closure, rather than assigning an existing closure, gets overwritten anyways.

change to r52888, since we dont always want ED_view3d_offset_distance() to give a corrected value, instead pass a fallback so callers don't allow zero by accident.

fix for building with msvc

image stamp data's strings could be short enough not to fit the entire ID name length.

replace BLI_array_fixedstack_declare with() new macro BLI_array_alloca() which uses stack memory always and doesn't need to be freed explicitly.
