Fix T56789: There was issue with certain driver with glGenerateMipmap and
GPU_DEPTH_COMPONENT24.
In this case we just create a complete texture with mipmaps manually
without downsampling / initializing the data.
This reorganizes the cloth UI, and changes some of the behaviour to be
more reasonable.
Changes included here:
* Reorganized cloth panels
* Improved some tooltips
* Removed `vel_damping` option
* Removed cloth pinning checkbox
* Removed stiffness scaling checkbox
* Separated shrinking from sewing
* Separated self collisions from object collisions

Avoids invisible objects from being considered visible when they
are used as driver variables.
If those cases are actually coming from a visible object, then
deg_graph_build_flush_visibility() will ensure visibility is
properly flushed there.
Allows to go to sculpt mode, do brush strokes, get out of sculpt mode
and have deformation preserved.
The issues currently is that the current implementation of CCG
storage is created from the limit surface, without displacement
taken into account. It is trivial to get displaced coordinates,
but it is more tricky to get displaced normals. This is something
to be solved next.
Another limitation is that this only works for sculpting at a maximal
multires level. There is code to be done to support propagation
of displacement onto a higher levels.
The function is supposed to be called for original object.
Draw manager abuses this a bit, will solve later by moving
PBVH (re)creation to dependency graph.
At the time being, stop adding object evaluation to draw
manager, this is really where it does not belong to.
Flat shaded grids are now rendered as a long triangle strip with
degenerate triangles.
Smooth shaded grids are not changed.
Also add back fast navigate. The only difference with 2.79 is that fast
navigate + flat shading will show slitly "incorrect" smooth face. But that's too
much effort to fix for what it is.
That bug probably did not affect 2.7x, only 2.8 with COW copying IDs in
threads... But root of the issue is that underlying boost i18n lib does
not support well multi-threaded access. So simply forbid any translation
from non-main thread. This *may* be an annoying limit at some point, but
doubt it will be any issue currently.
