Now that the new 3D viewport draws to a multisample offscreen buffer, there is
no good reason anymore to create an entire multisample window and pay the
performance/memory cost for other regions that don't need it.
GL_MULTISAMPLE now only gets enabled for offscreen buffers, so we don't need
to check for it throughout the UI code anymore.

This adds midlevel and object/world space for displacement, and a
vector displacement node with tangent/object/world space, midlevel
and scale.
Note that tangent space vector displacement still is not exactly
compatible with maps created by other software, this will require
changes to the tangent computation.

Previously only scalar displacement along the normal was supported,
now displacement can go in any direction. For backwards compatibility,
a Displacement node will be automatically inserted in existing files.
This will make it possible to support vector displacement maps in the
future. It's already possible to use them to some extent, but requires
a manual shader node setup. For tangent space maps the right tangent
may also not be available yet, depends on the map.

This converts object space height to world space displacement, to be
linked to the new vector displacement material output.

Brushes themselves are still affected by the mask, but the viewport is not
showing the mask. This way it's easier to see details while sculpting.

Was due to the fact that the instances don't have a "static" obmat that can be referenced to use as a uniform.
Solution : precompute the full matrix for each bone and pass it as instance data. (theses are copied into a buffer and can be discarded right away)
Note: this could be optimized further and make only one drawcall (shgroup) to draw all bone instance of one type (vs. one call per armature).
This is a special memory manager that keeps memory blocks ready to send as vbo data.
Since we loose which memory block was used each DRWShadingGroup we need to redistribute them in the same order/size to avoid to realloc each frame.
This is why DRWInstanceDatas are sorted in a list for each different data size.
ntree_shader_relink_displacement is creating a transient node that does not have a correct original to point to.
In this case we revert to constant uniform.
This option prevent from automatically blurring the albedo color applied to the SSS.
While this is great for preserving details it can bleed more light onto the nearby objects since the blurring will be done on pure "white" irradiance.
This issue is to be tackled in a separate commit.
