This commit contains all the remained parts needed for initial integration of
OpenSubdiv into Blender's subdivision surface code. Includes both GPU and CPU
backends which works in the following way:
- When SubSurf modifier is the last in the modifiers stack then GPU pipeline
of OpenSubdiv is used, making viewport performance as fast as possible.
This also requires graphscard with GLSL 1.5 support. If this requirement is
not met, then no GPU pipeline is used at all.
- If SubSurf is not a last modifier or if DerivesMesh is being evaluated for
rendering then CPU limit evaluation API from OpenSubdiv is used. This only
replaces the legacy evaluation code from CCGSubSurf_legacy, but keeps CCG
structures exactly the same as they used to be for ages now.
This integration is fully covered with ifdef and not enabled by default
because there are several TODOs to be solved first:
- Face varying data interpolation is not really cleanly implemented for GPU
in OpenSubdiv 3.0. It is also not implemented for limit evaluation API.
This basically means we'll have really hard time supporting UVs.
- Limit evaluation only works with adaptivly subdivided meshes so far, which
basically means all the points of CCG are pushed to the limit. This gives
different result from old code.
- There are some serious optimizations possible on the topology refiner
creation, which would speed up initial OpenSubdiv mesh creation.
- There are some hardcoded asumptions in the GPU and DerivedMesh areas which
could be generalized.
That's something where Antony and Campbell can help, making it so the code
is structured in a way which is reusable by all planned viewport projects.
- There are also some workarounds in the dependency graph to make sure OpenGL
buffers are only freed from the main thread.
Those who'll be wanting to make experiments with this code should grab dev
branch (NOT master) from
https://github.com/Nazg-Gul/OpenSubdiv/tree/dev
There are some patches applied in there which we're working on on getting
into upstream.
CCFLAGS are used for both C and C++ compilers and one is better not to pass
C-related flags to C++ compiler. C-compiler flags are to be passed via CFLAGS
variable.
We need to register the exception handler slightly differently here, as
well as adding DbgHelp as a library, but according to docs it should be
supported in recent Windows editions (Win XP included even).
We can try it first and revert if there are issues.
So, it turns out my changes here the other day were a bit too over-eager:
-Wdeclaration-after-statement and -Wstrict-prototypes only applied to C code
and not C++ (which that set of flags was getting included for too).
However, -Wno-char-subscripts is fine where it is now, so I've left it in place
The warning flags in C_WARN were not actually getting included
(most notably, the one disabling the pointless + braindead one
about using chars to index into arrays - given that we only use
unsigned chars everywhere). Maybe this should get done for the
other scons platforms too?
- fix dead blender.org link (build dependencies)
- rewrite $BLENDERHOME/{config,tools}/* to $BLENDERHOME/build_files/scons/{config,tools}/*

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 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.

Also move this to a generic place in SConstruct instead of having this
defines in 6 different configurations.
Should not be functional changes, but please verify all the platforms.
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.

This also updates the configurations to build kernels for compute capability
5.0 cards, when using and older CUDA toolkit version this will be skipped.
Also includes tweaks to improve performance with this version:
* Increase max registers on sm_30, sm_35 and sm_50
* No longer use texture storage on sm_30
Fixes T39423: Blender crashes on iv41 encoded videos in thumbnail display mode
Libraries are still being committed to the svn, so compilation might be broken
for a while. Sorry for this, but can't really be avoided.
Also, some typos in scons are possible.
Some int/float conversion warnings were disabled by buildsystems but
re-enabled by BLI_winstuff.h, the warnigns relate to conversions not
considered issues on other systems so better just quiet them.
