Fix T60132: Convert hair particles to mesh

Needed to port operator to use evaluated particle system.

But also changed interface to always show Convert button when
draw type is set to Path (Hair particle system is forced to
be draws as path). This avoid rather expensive lookup on every
redraw, but will show Convert button for un-baked particle
emitter.

Probably, an acceptable compromise.

Partial fix T60148: EEVEE hangs when anamorphic bokeh is too low

Fixed by setting the limit to the original limit I used for Cycles.
Rendering still goes extremely slow when bokeh is lower than 1.0.

But at least now it is "waitable". With lower numbers than 0.01 I don't
think we would ever get a render to finish.

@fclem feel free to address the real root of the problem, but I'm afraid
it may be a limitation of the algorithm you are using.

Fix T59768: UV context menu showing in image editor.

EEVEE DoF: Fix runtime error: division by zero when blades was 0

Even though the fragment shader was already discarding all members of
dof_bokeh_sides when blades was zero, the C code was still trying to
use this for a few divisions leading to runtime asserts.

Those are harmless yet can lead some to waste time while pursuiting
other bugs (namely a near freeze when blades aspect ratio is too low).

Fix T60044: Sculpting brush is not visible on file load

The original issue is that wm->paintcursors is empty until we go in and
out of the sculpt mode. To fix this we need to toggle inside the sculpt
mode.

This is usually tackled by ED_editors_init(), however the sculpt mode
toggling was never call because the object technically had "mode data".

Object: don't flip scale when setting dimensions

Fix T54771: Can't change multiple dimensions at once

- Use non-rna button for adjusting dimensions.
- Make Object.dimensions RNA read-only since it never worked well.
This is mainly a UI editing feature.

Cleanup: unused calculation

Fix T60099: Inconsistent normals from spin tool

Spin Tool: don't flip when using a negative angle

The intention was to flip normals when extruding in the opposite
direction, however the sign of the angle isn't meaningful unless
the geometry center and region normal are taken into account.

Disable, may add back in a way that works more predictably.
