This commit makes some preliminary fixes and tweaks aimed to make blender
compilable with C++11 feature set. This includes:
- Build system attribute to enable C++11 featureset.
It's for sure default OFF, but easy to enable to have a play around with
it and make sure all the stuff is compilable before we go C++11 for real.
- Changes in Compositor to use non-named cl_int structure fields.
This is because __STRICT_ANSI__ is defined by default by GCC and OpenCL
does not use named fields in this case.
- Changes to TYPE_CHECK() related on lack of typeof() in C++11
This uses decltype() instead with some trickery to make sure returned type
is not a reference.
- Changes for auto_ptr in Freestyle
This actually conditionally switches between auto_ptr and unique_ptr since
auto_ptr is deprecated in C++11. Seems to be not strictly needed but still
nice to be ready for such an update anyway/
This all based on changes form depsgraph_refactor branch apart from the weird
changes which were made in order to support MinGW compilation. Those parts of
change would need to be carefully reviewed again after official move to gcc49
in MinGW.
Tested on Linux with GCC-4.7 and Clang-3.5, other platforms are not tested and
likely needs some more tweaks.

Basically, before drawing X-Rays, we now bind a second depth buffer.
After drawing XRays, we do an extra resolve pass where we overwrite the
non-XRay depth buffer in pixels where the depth is not maximum (which
means background pixel, since depth is cleared before drawing X-Ray
objects).
This ensures both scene and X-Rays keep their depth values and are ready
for compositing. Well, the odd effect due to depth discontinuities can be
expected, and X-Rays are a bit more expensive (extra buffer + resolve pass)
but at least X-Rays won't invalidate depth values anymore. Whee!

This commit introduces a few ready made effects for the 3D viewport
and OpenGL rendering.
Included effects are Depth of Field, accessible from camera view
and screen space ambient occlusion. Those effects can be turned on and
tweaked from the shading panel in the 3D viewport.
Off screen rendering will use the settings of the current camera.

It is based on fmath.h from OIIO and could be used to give some speedup
in areas where absolute accuracy is not so critical.

Original patch by @random (D765) with some minor work done by @campbell
and me.
At this place, I'd like call out a number of people who were involved and
deserve a big "Thank you!":
* At the first place @randon who developed and submitted the patch
* The Blendercn community which helped a lot with testing - espacially
* @yuzukyo, @leon_cheung and @kjym3
* @campbellbarton, @mont29 and @sergey for their help and advises during
* review
* @ton who realized the importance of this early on and asked me for
* reviewing
We are still not finished, as this is only the first part of the
implementaion, but there's more to come!

This is added in the spirit of the general cycles GLSL system
which is pretty much WIP still.
This will only work on cycles at the moment but generating for blender
internal is possible too of course though it will be done in a separate
commit.
This hasn't been tested with all and every node in cycles, but
environment and regular textures with texture coordinates work.
There is some difference between the way cycles treats some coordinates,
which is in world space and the way GLSL treats them, which is in view
space.
We might want to explore and improve this further in the future.
...also </drumroll>

Configuration used to override the link flags, it better restore them
once the configuration is done.

This is mainly to address old issue when one need to have SDL library installed
in order to use our official builds. Some hip distros already installs SDL,
but it's not quite the same across all the variety of the distros.
We also now switching to SDL-2.0, most of the distros have it in repositories
already, so it shouldn't be huge deal to install it if needed.

Now we build 2 .cubins per architecture (e.g. kernel_sm_21.cubin, kernel_experimental_sm_21.cubin).
The experimental kernel can be used by switching to the Experimental Feature Set: http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Experimental_Features
This enables Subsurface Scattering and Correlated Multi Jitter Sampling on GPU, while keeping the stability and performance of the regular kernel.

Patch by Sergey and myself.
Developer / Builder Note:
CUDA Toolkit 6.5 is highly recommended for this, also note that building the experimental kernel requires a lot of system memory (~7-8GB).

Main idea of this change is to make a small executable which
will set OMP_WAIT_POLICY environment variable and then will
launch blender itself.
This is a teporary solution for the time being we'll have a
more clear solution to high CPU usage with OpenMP when building
with MSVC.

For now it was mainly about OpenCL wrangler being duplicated
between Cycles and Compositor, but with OpenSubdiv work those
wranglers were gonna to be duplicated just once again.
This commit makes it so Cycles and Compositor uses wranglers
from this repositories:
- https://github.com/CudaWrangler/cuew
- https://github.com/OpenCLWrangler/clew
This repositories are based on the wranglers we used before
and they'll be likely continued maintaining by us plus some
more players in the market.
Pretty much straightforward change with some tricks in the
CMake/SCons to make this libs being passed to the linker
after all other libraries in order to make OpenSubdiv linked
against those wranglers in the future.
For those who're worrying about Cycles being less standalone,
it's not truth, it's rather more flexible now and in the future
different wranglers might be used in Cycles. For now it'll
just mean those libs would need to be put into Cycles repository
together with some other libs from Blender such as mikkspace.
This is mainly platform maintenance commit, should not be any
changes to the user space.

- important: requires cmake >= 2.8.12 to read minor version right,
aka older cmake rates 10.10 lower than 10.6 for example ! ( sigh )

Yep, at last it's here!
There are a few minor issues remaining but development can go on in
master after discussion at blender institute.
For full list of features see:

Thanks to Sergey and Campbell for the extensive review and to the
countless artists that have given their input and reported issues during
development.

This way no access to automated tests variables will happen.
Ideally it should be something more like using blenderlite
with just Cycles enabled, but let's keep it for a bigger
clean up.
|

No need to run automated tests for cudakernels target. TThis could
be harmless because CUDA binaries are built in the another chroot.
|
|
We should do autotests only after setting path to sconsign,
otherwise using the same working directory and different
build directories will eventually break.
|
|
|
|
as we always get sdk properly fron ccflags in subcompiles
|
|
build environments and prepend SDK_FLAGS to CFLAGS always
|
|
Issue was caused by OSX tweaks happening in the SConstruct
after the old location of autotest.
|

Brings new bounds limiting and also prepares build system
for the changes in the upstream.
Namely shared_ptr header and namespace is now being detected
by a build system rather than by hacks in the code.
This commit includes some changes to auto-detection flags
in SCons, presumably adding more consistency there. This
is main changes which are suppoed to be reviewed here.

- moved assumed location of omp lib to blender libs
- prepared libiomp5 to link out of the box with cmake
- changed according in scons
- introduced a local var C_VENDOR, cause Apple clang 3.4 may not include omp support yet
- added a linklibs for msgfmt ( may not be needed for other than OSX )

use the svn clang version instead of Apple compiler naming,
this also makes Brecht’s cycles sse/avx conditionals behave right
