This is a second attempt to get the crash fixed. The original fix
worked, but it was reverted by d3e0d7f082.
Now the logic goes as:
- All pointers which we can not have shared (the ones which are
owned by the runtime) are cleared.
- The rest of runtime stays untouched.
This seems to be enough to keep particles happy.
This changes the bent normal effect to be a bit more subtle.
I also tuned down the bent normal blending factor so mesh faceted look may
appear more in occluded regions. this is to increase the fidelity of the
indirect lighting. This blending might be a parameter in the future.

This commit adds support for new curve tool and adds more functionalities to the existing primitives, including new handles, editing, stroke thickness curve, noise, preview of the real stroke, etc.
Thanks to @charlie for his great contribution to this improvement.
This replaces the test of consistency and capacity made with `GL_PROXY_TEXTURE_..` on AMD GPUs with one that checks only if the texture fits the limits of size and layer.

Pinning doesn't really change the geometry, so we don't really have a
tag for this. Using '0' for now (same we use for Mark Seam).
I will check with Sergey Sharybin which flag to use instead.
We could use ID_RECALC_GEOMETRY to match the notifier, but even the
simpler ID_RECALC_SELECT would do it.
NLA strips support using the keyframe values in a variety of ways:
adding, subtracting, multiplying, linearly mixing with the result
of strips located below in the stack. This is intended for layering
tweaks on top of a base animation.
However, when inserting keyframes into such strips, it simply inserts
the final value of the property, irrespective of these settings. This
in fact makes the feature nearly useless.
To fix this it is necessary to evaluate the NLA stack below the
edited strip and correctly compute the raw key that would produce
the intended final value, according to the mode and influence.

Basically uiRNACollectionSearch->but_changed was always NULL for the
search templates. So skip_filter would always be true, and we would
never filter.
An alternative fix would be to add the following to the begin of
`template_search_add_button_searchmenu`:
```
static bool always_true = true;
template_search->search_data.but_changed = &always_true;
```
This changes a bit the batches data structure. Instead of using one
vbo per material we use one for all material and use index buffers for
selecting the correct triangles.
This is less optimized than before but has potential to become more
optimized by merging the wireframe data vbo into the shading one.
Also the index buffers are not strictly necessary and could be just
ranges inside the buffer. But this needs more adding things inside
GPUIndexBuf.
Shaded triangles are not yet implemented (request from gpumaterials).
This also changes the mechanism to draw curve normals to make it not
dependant on normal size display. This way different viewport can
reuse the same batch.
