GP: Change canvas titles

These changes are to harmonize names.

Cleanup: convert smoke modifier from DerivedMesh to Mesh.

Cycles: keep material settings panel closed by default.

Revert "Fix: setUp of ID Property tests failed"

This reverts commit 52cee1a23c92d30b241d58f7ed65a951ff034dee.

Fix: setUp of ID Property tests failed

Subdiv: Fix crash subdividing mesh withotu faces

Multires: Support sculpting on a lover levels

Added propagation of displacement to a higher levels.

Has the same limitation as reshape from object, which makes
grids somewhat choppy due to linear interpolation nature.

This is to be addressed next.

Multires: Fix reshaping from object at lower level

This brings basic implementation of displacement propagation
to a higher levels. Currently does linear interpolation between
grid points at which reshape happened. It makes results a bit
choppy, proper solution would be to use some interpolation
weights from the limit patch.

UI: fractional DPI scaling of splash, instead of always 1x or 2x.

GP: Fix select tools from toolbar error

The operators used were not the right ones.

Fix minor typo in comment.

GP: Convert lock axis to popover

Fix missing edge in shape-to-wire utility

Gizmo: spin tool XYZ axis toggles

New handle type for initial spin,
gives clear differentiation between do & redo (similar to extrude).

Some tweaks still required to match T56571.

Gizmo: enable spin tool redo gizmos again

- Add x,y rotate and translate controls.
- Remove x-depth adjustment.

Gizmo: fix incorrect dial clip scaling

Failed with obvious error when the dials scale wasn't 1.0

Updated gpu.types.GPUOffscreen.py example file

The image I get is a bit too dark, which is the same I get in the viewport
itself when there is no Display Device. So I believe for cases like this
we need to have color management on top of the buffer.

Also, on EEVEE it looks like it needs to clear some extra buffers. You can see
that, by rotating the camera view around.

That said, this is the first step to bring back fun addons
that use external offscreen buffers.

Note: When using gpu offscreen with POST_VIEW (as oppose to POST_PIXEL)
I get a crash with DST having 0xFF..

Cleanup: style, use raw strings

Merge branch 'master' into blender2.8
