This commit integrates the work done so far on the new dependency graph system,
where goal was to replace legacy depsgraph with the new one, supporting loads of
neat features like:
- More granular dependency relation nature, which solves issues with fake cycles
in the dependencies.
- Move towards all-animatable, by better integration of drivers into the system.
- Lay down some basis for upcoming copy-on-write, overrides and so on.
The new system is living side-by-side with the previous one and disabled by
default, so nothing will become suddenly broken. The way to enable new depsgraph
is to pass `--new-depsgraph` command line argument.
It's a bit early to consider the system production-ready, there are some TODOs
and issues were discovered during the merge period, they'll be addressed ASAP.
But it's important to merge, because it's the only way to attract artists to
really start testing this system.
There are number of assorted documents related on the design of the new system:
* http://wiki.blender.org/index.php/User:Aligorith/GSoC2013_Depsgraph#Design_Documents
* http://wiki.blender.org/index.php/User:Nazg-gul/DependencyGraph
There are also some user-related information online:

* http://code.blender.org/2015/03/more-dependency-graph-tricks/
Kudos to everyone who was involved into the project:
- Joshua "Aligorith" Leung -- design specification, initial code
- Lukas "lukas_t" Toenne -- integrating code into blender, with further fixes
- Sergey "Sergey" "Sharybin" -- some mocking around, trying to wrap up the
project and so
- Bassam "slikdigit" Kurdali -- stressing the new system, reporting all the
issues and recording/writing documentation.
- Everyone else who i forgot to mention here :)
Doesn't mean we're 100% ready for the transition, but need to start somewhere
anyway. Changes:
- OSL is no longer supporting cpp and requires usage of Boost Wave.
So now Wave component of Boost is optionally demanded when looking for the
Boost libraries if OSL is enabled.
Only did this for Linux, MSVC seems already using Wave. Not sure about OSX.
- Because of the same reason OSL should be moved prior Boost for linker.
- Whole archive trick makes it so linking fails with duplicated symbols, so
removed it for the new OSL. Didn't see issues with this so far.
- Added some code to check OSL version on Linux. Would need to move all that
to FindOpenShadingLanguage.cmake which we can get from Cycles standalone
repository.
So in theory no affect on current stup would be made at all.
- Added some tweaks to buildbot files. It now seems to be happy with the new
OSL libraries, but again, those tweaks are not in action yet.
All this was tested on Linux only. Win/OSX might still need some tweaks to
support new OSL.
P.S. This doesn't mean we're pushing OSL update yet, just making some
preliminary tweaks to avoid entropy of PITA when we'll actually want to
switch.
code.
The implicit solver itself should remain agnostic to the specifics of
the Blender data (cloth vs. hair). This way we could avoid the bloated
data conversion chain from particles/hair to derived mesh to cloth
modifier to implicit solver data and back. Every step in this chain adds
overhead as well as rounding errors and a possibility for bugs, not to
speak of making the code horribly complicated.
The new subfolder is named "physics" since it should be the start of a
somewhat "unified" physics systems combining all the various solvers in
the same place and managing things like synchronized time steps.
Generally for build systems, libraries that do not depend on other
libraries, such as system libraries, OpenGL etc always go at the end.
We could even get rid of some duplicate dependency libraries here but
auto duplication by build systems and differences between OSs make this
difficult.
GTest still duplicates all libraries twice to solve some issues which is
weird (maybe libs are not sorted correctly for some reason? needs
investigation)
This commit contains all the tweaks which were missing in initial patch
re-integration from the standalone Cycles repository.
This commit also contains an utility cmake macro to help linking targets
with different libraries for release/debug builds, the name currently is
target_link_libraries_decoupled
it gets a target and list of libraries and makes sure debug builds are
using libraries with "_d" suffix.
After all this changes it'll hopefully be easier to interchange patches
between blender and standalone repositories, because they're now quite
identical.
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.

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.

This solves missing requests package reported on the systems where it's
located in dist-packages rather than in site-packages.
To do this there's now a helper macros which handles both requests and
numpy now and could be used for more packages in the future.

This patch creates an interface for selection mechanisms in opengl. This
makes it possible to switch between occlusion query based or select
rendermode based selection transparently.
This is really useful on graphics drivers that do not accelerate the
select rendermode path (some ATI cards are notorious for this, and the
new path is used by default there), since occlusion queries are always
hardware accelerated due to their use in games.
The option can be found under system - selection. Auto just enables
occlusion queries for ATI users while the rest of the options enforce
one of the two methods always.
There is just one known change, previous code enforced nearest bone to
always get selected, even when mouse selecting near the same position, I
couldn't replicate the behaviour though.
patch by me with edits and review by Campbell.
Thanks!
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.

Needed to make the blender link libraries a global property
now that tests are parallel to source directory.
Current sort order for blender link libraries doesn't work
for tests that start with few defined symbols. Doubling the
lib list works, but a TODO to find a better way (probably
using CMake's own mechanism for tracking dependencies).
Using unordered_map and unordered_set C++ container types currently
requires careful testing or usage of boost, due to the various confusing
C++ version differences in include paths and namespaces.
Libmv defines tests for these cases in cmake and scons, such that ceres
can use any available implementation, or fall back too std::map/std::set
if none can be found.
This patch generalizes this buildfile code by providing a Blender macro.
* cmake: defines both the variables used by libmv at them moment as well
as 2 variables UNORDERED_MAP_INCLUDE_PREFIX and UNORDERED_MAP_NAMESPACE,
which can later be used in other C++ parts for convenience.
* scons: adds a tool script returning the include prefix and namespace.
Libmv checks these to define the appropriate definitions for ceres.

this allows for updating icons without committing a new PNG each time
(which is inefficient with git). The data files are converted into a
PNG at builds time and used just as they were before.
Made it so if there's release/datafiles/locale/po
folder, then all the .po files will be converted
to .mo at blender compile time and installed to
an appropriate location.
Uses small own implementation msgfmt which is
based on msgfmt.py from Python project, but also
supports contexts.
There's no functional changes for until we've
switched to use source .po files instead of
pre-compiled .mo.
P.S. Well, there's one change which is msgfmt.cc
being compiled even if it's not used, but
would rather not clutter code with checks
since pretty soon we'll use this program
anyway.
Added new build option WITH_JACK_DYNLOAD for CMake and
WITH_BF_JACK_DYNLOAD for SCons, which means there'll be
no build-time linking against libjack and getting symbols
from libjack will happen runtime using dlopen and dlsym
tricks.
Alternative would be to use weak linking, but it'll require
having wrapper for preloading libjack.
This new options are disabled by default and they only
intended to be used on linux. Other platforms shall not
be using this and there shall be no functional changes
on non-linux platforms at all.
