This in fact seems some kind of video driver limitation, because it worked fine
on windows but failed on linux here. The guess is that textures doesn't always
work on display lists, or we simply do have some wrong OGL context somewhere.
This is a workaround for until bigger viewport draw refactor is done (as Brecht
mentioned display lists are deprecated in new OGL anyway).
Root of the issue goes to the order of particle initialization which does
texture evaluation (which does depend on particle coordinate) and particle
birth coordinate calculation. So basically what happened is:
* Changing number of particles re-allocated all the particles,
which sets their coordinate to (0,0,0)
* Texture evaluation used this non-initialized coordinate
* Coordinates were calculated for particles
Reshuffled code a bit so now texture evaluation happens after particles.
coordinate calculation. Basically moved texture evaluation to particle
reset function. Reset happens after initialization anyway and it does
know particle coordinates. Also, if reset is being called without init
then it's also kind of logical to re-evaluate texture because particle
coordinates might change.
As discussed in T38340 the solution is to use the current scene from
context whenever feasible.
Composite does not use node->id at all now, the scene which owns the
compositing node tree is retrieved from context instead.
Defocus node->id is made editable by the user. By default it is not set,
which also will make it use the contextual scene and camera info.
The node->id pointer in Defocus is **not** cleared in older blend files.
This is done for backward compatibility: the node will then behave as
before in untouched scenes.
File Output nodes also don't store scene in node->id. This is only needed
when creating a new node for initializing the file format.

COLOR widgets never get created with UI_GRAD_V_ALT values. This is
intended for HSVCUBE color sliders only so reverting this to old value
before it was substituted with a define, which was -1.
There's one case where COLOR buttons get defined with a1 value different
than -1 which is in ui_def_but_rna. There the step value of the RNA
property is used. However, that meant that if step equaled to 9, which
is UI_GRAD_V_ALT value (unlikely) or if UI_GRAD_V_ALT was changed to 10
in future, or we added check for e.g. UI_GRAD_L_ALT which is 10 in HCL
branch, color widget would not get a color selection menu spawned.
Support for tagging polygon numbers when adding scanfill data,
saves having to calculate connectivity afterwards (which can take approx half overall scanfill time for complex curves).
The documentation for the -b/--background option incorrectly states that it
takes a <file>, however it can run also without a file with e.g. a script.

Issue was caused by NULL-pointer de-reference when post-processing
the frame without putting the frame to movie cache.

Issue was in fact in strip update code when transforming, in case we move both left and right
handles the strip is handled twice in the loop, but it was always updated at the end of the
first loop only...
Crash was caused by missing curve_cache due to cyclic dependency.
This commit is rather a workaround, but we couldn't really guarantee
proper behavior in cases with cyclic dependency. So rather than calling
object update directly as it used to be let's don't perform curve
deform and be safe for threading instead.
Issue was caused by clearing dirty flags from element table in bmesh before
the data was fully ready.
This confused checks happening from threads and some threads did consider
element table is usable while other thread was still filling it in.
The Fix in 273 creates a backward incompatibility:
Collada files that have been created with an older Blender version
will contain the spotlight_size in Radians where Collada wants
this value to be in DEGREE.
This fix adds a check for the Blender Version that was used to create the
Collada file. If the Collada file was made by an older version of Blender
then the importer will assume that spotlight_size is specified in RADIANS.
