We had too many warnings lately... was awaiting that someone would kill them - didn't happen -> goes to my commit ratio! :P

This was already the case for most users of ray-cast.
Doing this avoids 2x normalize calls per ray-cast in many places.

- Add blentranslation `BLT_*` module.
- moved & split `BLF_translation.h` into (`BLT_translation.h`, `BLT_lang.h`).
- moved `BLF_*_unifont` functions from `blf_translation.c` to new source file `blf_font_i18n.c`.

ImBuf types were getting stored as bitflags in a 32bit integer which had
already run out of space. Solved the problem by separating file type to
an ftype enum, and file specific options to foptions.

The issue was caused by the conflict between preview render which would set
R_NO_IMAGE_LOAD flag on the renderer and texture samplers called outside of
the render pipeline trying to use this flag.
Now the sampler functions accepts extra argument so render pipeline can
still skip image load, but calls outside of the pipeline will nicely load
all the images.
Not cleanest change in the world but good enough to unlock gooseberry team,
and assuming we already had pool passed all over the place it should be all
fine.
Will need to reshuffle arguments into SamplerOptions structure later.

Makes usage of those funcs much more clear, we even had mixed '!strcmp(foo, bar)'
and 'strcmp(foo, bar) == 0' in several places...

Opted to keep includes if they are used indirectly (even if removing is possible).

Normals for each kdtree node were allocated but never used,
and search args only use in particles/boids code.

updates.
This file crashes on loading with NULL pointer access to curve_cache:
{F77132}
The pdInitEffectors function was amalgamating the simple
collection of effector objects with an automatic precalculation for
curve guides and the like. This precalculation requires object data
that may not be available until the DAG has finished.
Since for DAG dependencies only the list of effectors is required,
added an argument to disable precalculation when collecting effectors.

Summary:
Made objects update happening from multiple threads. It is a task-based
scheduling system which uses current dependency graph for spawning new
tasks. This means threading happens on object level, but the system is
flexible enough for higher granularity.
Technical details:
- Uses task scheduler which was recently committed to trunk
(that one which Brecht ported from Cycles).
- Added two utility functions to dependency graph:
* DAG_threaded_update_begin, which is called to initialize threaded
objects update. It will also schedule root DAG node to the queue,
hence starting evaluation process.
Initialization will calculate how much parents are to be evaluation
before current DAG node can be scheduled. This value is used by task
threads for faster detecting which nodes might be scheduled.
* DAG_threaded_update_handle_node_updated which is called from task
thread function when node was fully handled.
This function decreases num_pending_parents of node children and
schedules children with zero valency.
As it might have become clear, task thread receives DAG nodes and
decides which callback to call for it.
Currently only BKE_object_handle_update is called for object nodes.
In the future it'll call node->callback() from Ali's new DAG.
- This required adding some workarounds to the render pipeline.
Mainly to stop using get_object_dm() from modifiers' apply callback.
Such a call was only a workaround for dependency graph glitch when
rendering scene with, say, boolean modifiers before displaying
this scene.
Such change moves workaround from one place to another, so overall
hackentropy remains the same.
- Added paradigm of EvaluaitonContext. Currently it's more like just a
more reliable replacement for G.is_rendering which fails in some
circumstances.
Future idea of this context is to also store all the local data needed
for objects evaluation such as local time, Copy-on-Write data and so.
There're two types of EvaluationContext:
* Context used for viewport updated and owned by Main. In the future
this context might be easily moved to Window or Screen to allo
per-window/per-screen local time.
* Context used by render engines to evaluate objects for render purposes.
Render engine is an owner of this context.
This context is passed to all object update routines.

also replace callocs with mallocs since zeroing memory can be avoided.

It greatly helps getting rid of that "noise" that occurs if you use really steep objects (like cubes) as a brush. New default value is 1.0 which is just high enough to only get rid of the sharpest spikes, so if you want really smooth waves it's better use higher values.
This also seems to "fix" bug [#35413].

inconsistency between 2.67/2.68RC and previous versions
This was in fact really nasty bug, caused by multitex_nodes
function using global variable R (which is a copy of current
renderer). this variable is not initialized to anything
meaningful for until first rendering (preview or final)
happened.
Since multitex_nodes might be used outside of render pipeline,
made it so whether CM is on or off as an argument to functions
multitex_ext_safe and multitex_ext. Now multitex_nodes() is
only shall be used for stuff happening from render pipeline!
Also needed to make some changes to other places, so all the
usages of texture sampling knows for the fact whether CM is
on or off.
And one more change is related on behavior of dispalcement,
wave, warp, weightvg modifiers and smoke. They'll be always
using CM off since texture is used for influence, not for
color.
It's rather bigger patch, but it's mostly straightforward
changes, which we really need to be done.

but its not needed.
Now add asserts to make sure this layer is only added once the modifier stack has been calculated.
this saves normal layer being calculated whenver vertex normals need updating.
|
|
Also done a few cleanup here and there...
|
|
- remove unused defines.
- quiet some shadow warnings.
- bevel, ifdef out some asserts that are too common.
- style

through parent chain longer than 2 objects.
Maximum number of parents updated is now 5. Hopefully this will be enough until Blender has better subframe sampling system.
