Fix T39286: Display percentage ignored in Cycles viewport.
The threaded depsgraph update changes included a cleanup of the global
is_rendering flag, which was replaced by a general EvalContext being
passed to dupli functions.
Problem is that the global flag was true for viewport duplis before
(ugly hack), which was used as a check for generating dupli orco/UV from
mesh data layers. The new flag is stricter and only true for actual
renders, which disables these attributes and breaks the Cycles
Texture Coordinates and UVMap nodes.
The solution is to extend the simple for_render boolean to an enum:
* VIEWPORT: OpenGL viewport drawing (dupli tex coords omitted)
* PREVIEW: Viewport preview render (simplified modifiers)
* RENDER: Full render with all details and attributes
There are still some areas that need to be examined, in particular
modifiers seem to totally ignore the EvaluationContext!
Instead they generally execute without render params from the depsgraph
(BKE_object_handle_update_ex) and are built with render settings
explicitly.

New properties 'line_color' and 'line_priority' are added to Material ID data blocks.
The 'line_color' property allows users to specify a per-material line color that can be
used as a Freestyle line color through Material color modifiers of line style settings.
The new line color property is intended to provide a solution for line color
stylization when a proper Freestyle support for Cycles is implemented (likely
as part of the upcoming Blender 2.72 release; see Patch D632). Materials in
Cycles are usually set up using shader nodes, and Freestyle won't be capable
of retrieving colors and other properties from node-based materials any soon.
The new line color property of materials addresses this foreseen limitation by
providing artists with an intuitive alternative mean to specify line colors on a
per-material basis independently from node trees.
The 'line_priority' property gives users a way to control line colors at material
boundaries. When a line is drawn along a feature edge at material boundaries,
one of the two materials on both sides of the edge has to be picked up to
determine the line color. So far there was no way to control this selection
(which was in effect at random). Now the material with a higher line color
priority will be selected.
The new per-material line settings are shown in the new Freestyle Line tab in
the Material context of the Properties window (only when Freestyle is enabled).
In rB78c491e the `initialize_particle` function was split into 2 parts for particle texture initialization.
The texture init part however also initializes birth times, which is now missing in the main init function
in some cases (notably when setting start/end directly without a subsequent time step).
Blender Internal only uses materials with non-zero user counter for SSS and new
mutable libblock copy was keeping users counter at zero.
Now it sets user counter to 1, which is a bit of arguable decision, but which
also kind of makes sense -- meaning callee owns the copied block.
A bit hackish solution for now, cleaner solution we'll look into as a
part of the new DAG project, when it's clear what kind of data is passed
to the evaluation callbacks.
This way it's not needed to include BLI_threads.h from the
BKE_main.h which helps avoiding adding PThreads includes to
each library which uses Main on Windows.
From the API point of view it's now MainLock* and to lock or
unlock the main you're to use BKE_main_(un)lock().
This solves compilation error on Windows with SCons.
Disclaimer: The author of this patch is Geoffrey Gollmer (gomer). I only updated the patch to the current git master status, reworked several parts to fit well with current coding style and applied several fixes.
This actuator allows users to show/hide the mouse cursor using logic bricks, as well as control object rotation with a mouse in the BGE.
The mouse rotation is flexible enough to allow any type of mouse look, as well as banking for flight controls.

Added a lock to the Main which is getting acquired and released
when modifying it's lists.
Should not be any functional changes now, it just means Main is
now considered safe without worrying about locks in the callee.
Current temporary data of Blender suffers one major issue - default 'temp' dir on Windows is never
automatically cleaned up, and can end being quite big when used by Blender, especially when we have
to store per-process data (using getpid() in file names).
To address this, this patch:
* Divides tempdir paths in two, one for 'base' temp dir (the same as previous unique tempdir path),
the other is a mkdtemp-generated sub-dir, specific to each Blender instance.
* Only uses base tempdir when we need some shallow persistance accross Blender sessions - and we always
reuse the same filename (quit.blend...) or generate small file (crash reports...).
* Uses temp sub-dir for heavy files like pointcache or renderEXRs (Save Buffer option).
* Erases temp sub-dir on quit or crash.
To get this working it also adds a working 'recursive delete' to BLI_delete() under Windows.
Note that, as in current code, the 'recover render result' hack-feature that was possible
with SaveBuffer option is still removed. A real renderresult cache feature will be added
soon, though.

When converting text to value, units' "value" had only 6 digits of precision,
leading to annoying loss of precision esp. when mixing big and small units
(like e.g. miles and inches).
