use int's for kdopbvh start/stop axis since there were loops comparing with other ints.

use min_ii/max_ii over MIN2 MAX2

fix [#32855] Obj im and export and the file path and name

file selector now uses previously used settings for operators rather then over riding them with the currently open blend file.

comment R_SEQ_GL_REND flag, opengl render now does gl previews.

- enable GPU mipmap generation by default (Sergey and I wanted to change this before but it was too close to release).
- set opengl-solid display for the sequencer preview.

enable rendering from the sequencer again. this was working since 2.4x and shouldn't have been disabled.

rename axis_primary_v3() to max_axis_v3() to avoid confusion with axis_dominant_v3(). also add min_axis_v3().

Final fix for [#31017] Particles not generated on Grid Distribution
* In some cases a quad would be intersected twice so particles near this double-intersection point were not generated in grid distribution due to being marked as outside the surface.

Partially replace convex hull implementation with Bullet implementation

* Bullet's convex hull implementation is significantly more robust
than the one I implemented, as well as being faster.

* This fixes bug [#32864] "Convex Hull fails in some cases."
projects.blender.org/tracker/?func=detail&aid=32864&group_id=9&atid=498

That bug, and others like it, relate to the poor handling of
co-planar surfaces in the input. Pretty much any model that is
simple-subdivided a few times gave very bad results before, Bullet's
implementation handles this much better.

* In order to ensure a smooth transition, the Bullet output is
translated into the existing HullTriangle hash structure. This makes
it easy to ensure that the existing slot output stays the same; the
interactions between the slots are somewhat complicated, detangling
is a TODO.

Patch Bullet to make it's convex hull implementation usable in BMesh

* Add access to the original indices for vertices

* Add a very simple C API for convex hull

* Add this patch to the patches folder and update readme.txt

Separate languages file generation code into its own script (much better this way, so that we can regenerate that file without update whole trunk!).

Also add es_ES (Spanish from Spain) language, as we have a po for it!

Fix #2 for [#32954] Crash when activating 'International Fonts' in User Preferences

I though allocating zero-sized mem would return a NULL pointer, but it looks like it does not... :/ Anyway, Blender should no more crash in case languages file is missing, will just use default (system) locale...

Fix #27834: AAO color bleeding failure case with raytraced shadows.

Fix knife sensitivity issue (#30637): better calculation of how
to clamp distances in ortho mode.

Cycles: update buffers only once in a while when progressive refine is used

It'll mimic the same behavior as regular tile rendering update and it should
give pretty noticeable boost on simpler scenes.

Solve unresolved call of min(int&, unsigned int&)

Alternative could be using unsigned ints for min/max chunks.

Fix #32951: Progressive refine crashing Blender when used with multiple cuda

Issue was caused by offline rendering could have been allocated the same tile
to different devices and in this case buffers would become invalid.

Made it more clear in the code, so now it's flag for tile manager to indicate
whether tiles should always be allocated for the same device or not.

Also cleaned a way how tile index for progressive refine is calculating,
which is now avoids tricky computation based on tile coordinate and it's
dimensions.

reduce float comparisons for keying operation and despill.

use min_ max_ functions in more places.
also fix minor error in MOD decimate when the modifier did nothing the reported face count would be wrong.
