* Added the Phong BRDF from the inbuilt OSL shader library.
This can be used in OSL shaders only for now:
* phong(normal N, float exponent)
* phong_ramp(normal N, float exponent, color colors[8]
- when renderlayers could not be found in save_render_result_tile() blender would crash.
- RE_engine_end_result() / rna end_result() didn't set result argument as required.
... also some style cleanup.
This does not actually work: The context must not be shared between threads, but using the same context between different samples actually seems to prevent OSL from switching between shaders. The proper solution would be to ensure memory pooling works correctly.
This reverts commit 69f87e69258d6266dcb20f09f7e3d4021e663432.
This means that modifier would operate on buffer which was passed to it,
without creating copy of image buffer and operating on it.
All current modifiers fit into this model and if it would need to have
original buffer on modifier calculation, that particular modifier can
create copy.
Gives some percentage of boost.
Initial idea of this input was re-designed in a bit more flexible
way using modifiers.
Also since Color Balance (which was the only thing using effect
mask input) was moved to the modifiers, this input field became
rudiment.
It's pretty tricky to write versioning code to prevent possible
data in cases this field was used, but hope it wouldn't be difficult
to switch to modifiers masks.
Having two ways to control color balance now seems a bit overkill
and not clear.
Removed old Color Balance settings from the interface and logic,
added versioning code to convert this settings to modifier.
Unfortunately, since color balance was a pointer, it's not actually
possible to preserve compatibility of old files saved in new
blender and opened back in old blender.
Hopefully there's no regressions :)
Regular rendering now works tiled, and supports save buffers to save memory
during render and cache render results.

Various bug fixes by Sergey and Campbell.
* Fix for reading freed memory in some node setups.
* Fix incorrect memory read when synchronizing mesh motion.
* Fix crash appearing when direct light usage is different on different layers.
* Fix for vector pass gives wrong result in some circumstances.
* Fix for wrong resolution used for rendering Render Layer node.
* Option to cancel rendering when doing initial synchronization.
* No more texture limit when using CPU render.
* Many fixes for new tiled rendering.
during a WM_draw. tiny is max 8* size of pointer and it is maintained at
that size. So no worries there.
* cleanup some code to be certain that deinitialization happens
correctly.
