UI: add non-linear slider support

This patch introduces non linear sliders. That means, that the movement
of the mouse doesn't map linearly to the value of the slider.

The following changes have been made.

- Free logarithmic sliders with maximum range of (`0 <= x < inf`)
- Logarithmic sliders with correct value indication bar.
- Free cubic sliders with maximum range of (`-inf < x < inf`)
- Cubic sliders with correct value indication bar.

Cubic mapping has been added as well, because it's used for brush sizes
in other applications (Krita for e.g.).

To make a slider have a different scale type use following line in RNA:
`RNA_def_property_ui_scale_type(prop, PROP_SCALE_LOGARITHMIC);`
or:
`RNA_def_property_ui_scale_type(prop, PROP_SCALE_CUBIC);`

Test the precision, step size and soft-min if you change the scale type
of a property as it will feel very different and may need tweaking.

Performance: GPU Batch Baseline TestCase.

When using a dense mesh and transforming a small number of verts the mesh received a copy-on-write signal. This will free all GPU batches. No reuse is currently possible.
This patch adds a test case that can be used as a baseline to optimize the cache construction in the draw module.

USD Import: don't modify import params.

Fixed the unit conversion code to avoid changing the
import params scale member, to keep the params identical
to what the user specified. Also updated the USDXformReader
logic to use the scale value stored in the settings, to take
into account the unit scale factor.

Dyntopo now updates the existing pbvh on undo instead of building
a new one from scratch, an operation that can be slow despite being
threaded.

PBVH building is a memory bound operation (not just on the CPU side
either, remember the draw buffers have to be fully regenerated too).
Incrementally updating it this way is enormously faster (about as fast
as non-dyntopo undo).

The downside is we don't have the convienience of users regularly
building the pbvh from scratch anymore. Dyntopo does try to
join empty PBVH nodes (which happens after every stroke), but
that's not a complete substitute for a decent tree balancer.
That's on the todo list.
