A new option (set in the properties region) allows the user to pick the
"new viewport" for the rendering (in the UI: Modern Viewport).
For now we have a semi-blank file (view3d_draw.c) that can starts to take
over the drawing pipeline.
I can't guarantee we will be able to keep both drawing systems working
through the entire 2.8 development, but it should do for now.
also, we can use branches for some of the viewport development, but it's
better to keep things in 2.8 whenever we can, so people can test it.
Mostly this is making inlining match CUDA 7.5 in a few performance critical
places. The end result is that performance is now better than before, possibly
due to less register spilling or other CUDA 8.0 compiler improvements.
On benchmarks scenes, there are 3% to 35% render time reductions. Stack memory
usage is reduced a little too.

We *always* want to increase mat user count when from Object (and not
Data), because in that case we are moving mat from object to temp
generated mesh, material can never be 'borrowed' in that case.

If I didn't miss anything these are indeed not used. Old themes should still work (will only print info on redundant theme defines into console), but updated non-contrib themes already.
Fixes for clamp-omp, fewer shared variables, fix some cases of threads writing
to the same memory location. Issue found by Jens Verwiebe, who reports 30%
speedup with 16 core CPU, when using this with a recent clang-omp version.
Transition away from GLU and legacy matrix stack. Using point sprites eliminated the need for most of the matrix math!
Depends on decent support of large aliased points. NVIDIA is good at this, must test limits on AMD & Intel systems.
Still needs proper scaling based on view zoom.

Apparently GL_POINT_SPRITE is important to GL 3.2+ compatibility profile, not just to GL 2.1 as thought.
We'll remove this during the core profile transition.
- Explicitly specify the platform for msbuild, to facilitate builds with just the Visual C++ Build Tools installed.
- When vs2013 is not found, try looking for 2015 as a fallback
- Clear up any batch variables that might have been set from previous runs
This is also an important mathematical operation that can be folded
if it is known that one argument is a certain constant. For colors
the operation is provided as a Gamma node.
The SVM Gamma node needs a small fix to make it follow the 0 ^ 0 == 1
rule, same as the Power node, or the Gamma node itself in OSL mode.

At context startup, make sure our assumptions about the OpenGL version are true. Should match since we set up the contexts... but this is what asserts are for, to check "should"s!

'camera' Object pointer of TimeMarkers is a 'temp' hack since Durian project...
Would need to be either made definitive now, or removed/reworked/whatever.
But since we intend to use that object pointer for other needs, and current code
could lead to crashing .blend files, for now let's fix that mess (was missing
some bits in read code, and also totally ignored in libquery code).
Should be safe for 2.78a.

Notes from drawvertsN function:
this used to be called twice (once for selected/active, once for unselected -- guess: to avoid state switches[color]?)
this used to be called in a loop, too (subcurves), moved the loop here to avoid multiple init stuff
Part of T49043
It will discard the whole tile, but it's still kind of more friendly than
fully locked interface (sort of) for until tile is fully sampled.
Sorry if it causes PITA to merge for the opencl split work, but this issue
bothering a lot when collecting benchmarks.
