0579eaae1f Cycles: Make all #include statements relative to cycles source directory
The idea is to make include statements more explicit and obvious where the
file is coming from, additionally reducing chance of wrong header being
picked up.

For example, it was not obvious whether bvh.h was refferring to builder
or traversal, whenter node.h is a generic graph node or a shader node
and cases like that.

Surely this might look obvious for the active developers, but after some
time of not touching the code it becomes less obvious where file is coming
from.

This was briefly mentioned in T50824 and seems @brecht is fine with such
explicitness, but need to agree with all active developers before committing
this.

Please note that this patch is lacking changes related on GPU/OpenCL
support. This will be solved if/when we all agree this is a good idea to move
forward.

bc652766e8 Cycles: Expose passes size to device tasks
This is needed so devices can know the size of a tile buffer before any
tiles are acquired.

a2ebc5268f Cycles: Refactor Progress system to provide better estimates
The Progress system in Cycles had two limitations so far:
 - It just counted tiles, but ignored their size. For example, when rendering a 600x500 image with 512x512 tiles, the right 88x500 tile would count for 50% of the progress, although it only covers 15% of the image.
 - Scene update time was incorrectly counted as rendering time - therefore, the remaining time started very long and gradually decreased.

This patch fixes both problems:
First of all, the Progress now has a function to ignore time spans, and that is used to ignore scene update time.
The larger change is the tile size: Instead of counting samples per tile, so that the final value is num_samples*num_tiles, the code now counts every sample for every pixel, so that the final value is num_samples*num_pixels.

Along with that, some unused variables were removed from the Progress and Session classes.

92774ff792 Cycles: Use explicit qualifier for single-argument constructors
Almost in all cases we want such constructors to be explicit, there are
exceptions but only in few places.

9a76354585 Cycles-Bake: Custom Baking passes
The combined pass is built with the contributions the user finds fit.

It is useful for lightmap baking, as well as non-view dependent effects
baking.

The manual will be updated once we get closer to the 2.77 release.
Meanwhile the new page can be found here:

3918c8b9a5 Cycles: Optionally output luminance from the shader evaluation kernel
This makes it possible to move some parts of evaluation from host to the device
and hopefully reduce memory usage by avoid having full RGBA buffer on the host.

b3299bace0 Cycles: Pass requested tile size to the device via device task
This is currently unused but crucial for things like calculating amount of
device memory required to deal with the tasks.

Maybe not really best place to store it, but consider it good enough for now.

29f6616d60 Cycles: viewport render now takes scene color management settings into account,
except for curves, that's still missing from the OpenColorIO GLSL shader.

The pixels are stored in a half float texture, converterd from full float with
native GPU instructions and SIMD on the CPU, so it should be pretty quick.
Using a GLSL shader is useful for GPU render because it avoids a copy through
CPU memory.

a18112249d Cycles / Non-Progressive integrator:
* Non-Progressive integrator is now available on the GPU (CUDA, sm_20 and above). 

Implementation details:
* kernel_path_trace() has been split up into two functions:
kernel_path_trace_non_progressive() and kernel_path_trace_progressive().

* We compile two CUDA kernel entry functions (in kernel.cu) for the two integrators, they are still inside one .cubin file but due to the kernel separation there should be no performance problem. I tested with the BMW file on my Geforce 540M and the render times were the same for 100 samples (1.57 min in my case).

This is part of my GSoC project, SVN merge of r59032 + manual merge of UI changes for this from my branch.

3b88a29abf Cycles: progressive refine option
Just makes progressive refine :)

This means the whole image would be refined gradually using as much
threads as it's set in performance settings. Having enough tiles is
required to have this option working as it's expected.

Technically it's implemented by repeatedly computing next sample for
all the tiles before switching to next sample.

This works around 7-12% slower than regular tile-based rendering, so
use this option only if you really need it.

This commit also fixes progressive update of image when Save Buffers
option is enabled.

And one more thing this commit fixes is handling display buffer with
Save Buffers option enabled. If this option is enabled image buffer
wouldn't have neither byte nor float buffer until image is fully
rendered which could backfire in missing image while rendering in
cases color management cache became full.

This issue solved by allocating byte buffer for image buffer from
tile update callback.

Patch was reviewed by Brecht. He also made some minor edits to
original version to patch. Thanks, man!
