Fix#21187: 2.5svn26947 - particles + meta sphere = crash in rendering
Use separated displists for mballs in view3d and render stuff.
Do not recalculate displist for view3d while rendering - mball.c
uses several global variables which shouldn't be accepted from
parallel threads.
* Fractional frames support has been changed to use a new var, scene->r.subframe.
This is a 0.0-1.0 float representing a subframe interval, used in generating a final float
frame number to evaluate animation system etc.
* Changed frame_to_float() and some instances of bsystem_time() into a convenience function:
float BKE_curframe(scene) which retrieves the floating point current frame, after subframe
and frame length corrections.
* Removed blur_offs and field_offs globals. These are now stored in render, used to
generate a scene->r.subframe before render database processing.
by default now on all platforms since it shouldn't crash anymore if SSE is
not there. If this breaks compilation on some platforms, please let me know.
* Enabled premultiplication for packed images
* Added pack/unpack operator to image template
* Moved brightness/contrast corrections to after de-premultiplication in image texture sampling
- on instances last hit optimization was jumping to the last hit face
inside an instance without doing space transformation.
Fixed by making last hit optimization jump to the root node of the instance
instead of the last hit face.
* Path drawing now works for non hair particles.
* Should fix the following bugs too:
[#21316] Hair weight drawing is wrong
[#21923] Consistent Crash When Rendering Particle Scene.
[#21950] Path rendering option for particles causes crash
Now, rather than the bit-too-alarming stop sign, threaded wmJobs
display a progress indicator in the header. This is an optional feature
for each job type and still uses the same hardcoded ui template
(could use further work here...).
Currently implemented for:
Render - parts completed, then nodes comped
Compositor - nodes comped
Fluid Sim - frames simulated
Texture Bake - faces baked
Example: http://mke3.net/blender/devel/2.5/progress.mov
- fix implicit decloration of DAG_scene_sort()
- same fix for tiff as made in renderbranch
- rename 'combined peak' --> 'peak' for shorter messages while rendering.
* Take border render into account when drawing grid before for render
result becomes visible.
* Use antialiasing for rendering icon previews.
* Fix Full Sample not drawing render result while rendering.
* Mesh Deform Modifier: also forgot to commit this file.
* Division by zero fix for TNT SVD code.
* Sound fix, in case ffmpeg decode fails, don't use the samples.
* Fix for incorrect bounds of transformed objects in new raytracing code.
* Gave memory arena's a name used for allocations for easier memory
usage debugging.
* Dupligroup no_draw option was using layers but not restrict view/render
setting. (not a bugfix exactly but would do display list context switching
while drawing for no reason).
* Fix objects instanced on hair particles not giving consistent results
when the object is transformed.
* New math functions: madd_v4_v4fl, len_squared_v3v3, interp_v4_v4v4v4,
mul_v4_m4v4, SH and form factor functions, box_minmax_bounds_m4.
* mul_m4_m4m4 and mul_m3_m3m3 now accept the same pointers for multiple
arguments.
* endjob callback for WM jobs system.
* Geometry node uv/color layer now has search list/autocomplete.
* Various small buildsystem tweaks, not strictly needed yet in trunk.
* Some cases of struct name being set where it shouldnt have been.
* Spelling: wich --> which
* Copy and initialize uv modifier scale, remove unneeded enum.
* Ability to pin any object into the context.
* Update uv window while transforming (useful when used with UVProject modifier)
* Patch by Wahooney, so new template's are internal text and dont get saved over
by mistake.
* Fix for https://bugzilla.redhat.com/show_bug.cgi?id=572186
Bug 572186 - [abrt] crash in blender-2.49b-5.fc12: Process
/usr/bin/blender.bin was killed by signal 6 (SIGABRT). Original fix submitted
by Jochen Schmitt.
* [#21816] bpy.data.add_image has stopped working on Windows. moved to
bpy.data.images.load(), missed this call.

mask, also avoid making vertex groups if they will not be filled.
* Add back image pin option in image editor header.
* Fix deep shadow not respecting Cast Buffer Shadows option.
* Tangent space normal map baking should work again now.
* Fix a problem with particle duplis, due to own bugfix for #20350,
the problem for that seems to be in dupliverts, not particles.
* Fix external multires data link getting lost on exiting editmode.

if compositing, sequencer, fields, etc should be rendered, or if the
render does that itself. The weak point is that this only applies to
rendering, so if you open the compositor, it will still run on the
rendered result. Enabled by default, set to False to disable.
* Viewer node could free image while it is being redrawn, viewer image
buffers now need acquire/release to be accessed as was already the
case for render results.
* The Composite node could free the image buffers outside of a lock,
also causing simultaneous redraw to crash.
* Especially on Windows, re-rendering could crash when drawing an image
that was freed. When RE_RenderInProgress was true it would access the
image buffer and simply return it while it could still contain a pointer
to a render result buffer that was already freed. I don't understand
why this case was there in the first place, so I've removed it.
Possibly fixes bugs #20174, #21418, #21391, #21394.
