ccead2ed9c Spreadsheet: Display geometry volume component grids
This shows a geometry's volume grids in the spreadsheet.
Three columns are displayed:
 - Name: The text name of each grid
 - Data type: Float, Vector, etc.
 - Class: Fog volume, Level Set, or unkown

In the future, values of the voxels themselves could be displayed,
but that is a much more complex problem, with important performance
implications, etc.

cd03f5b6e5 Add RNA path funcs for VolumeRender & VolumeDisplay
Without proper RNA paths, Alt-click editing properties on multiple
selected objects doesn not work (as well as the 'Copy To Selected'
operator).

Fixes T91806.

fd414b4906 Cleanup: Use const arguments for volume code
The problem was that you could getting write access to a grid from a
`const Volume *` without breaking const correctness. I encountered this
when working on support for volumes in the bounding box node. For
geometry nodes there is an important distinction between getting data
"for read" and "for write", with the former returning a `const` version
of the data.

Also, for volumes it was necessary to cast away const, since all of
the relevant functions in `volume.cc` didn't have const versions. This
patch adds `const` in these places, distinguising between "for read"
and "for write" versions of functions where necessary.

The downside is that loading and unloading in the global volume cache
needs const write-access to some member variables. I see that as an
inherent problem that comes up with caching that never has a beautiful
solution anyway.

Some of the const-ness could probably be propogated futher in EEVEE
code, but I'll leave that out, since there is another level of caching.

6471cf6bc8 UI: Clean up labels and descriptions: "Draw" to "Display"
In Blender, we used to use the term 'draw' to refer to information
displayed to the user. For version 2.80, it was decided to change these
instances to 'display' instead. This was to avoid the ambiguity between
end-user drawing tools and display options.

From the Oxford English Dictionary:
 - Draw: produce (a picture or diagram) by making lines and marks on
   paper with a pencil, pen, etc.
 - Display: show (data or an image) on a computer, television, or
   other screen.

Therefore, we should use draw when referring to drawing tools for
making marks, but use display when referring to information
shown/displayed to the user. From a user POV, the computer displays
certain information, whereas the user draws a mark.

Apparently this change was not implemented consistently, so this patch
changes all remaining relevant instances of "draw".

2917f550ca Cleanup: Fix capitalization in various UI strings
Approximately 195 changes of capitalization to conform to MLA title style.
UI labels and property names should use MLA title case, while descriptions
should be capitalized like regular prose, generally with only the start of
a sentence capitalized.

fc767502dc Python API: add volume.grids.save(filepath) to save grids and metadata to disk
Particularly useful now that we can dynamically generate volume using
modifiers. Not exposed in the user interface currently, but it can be used
by add-ons that need to export an entire scene including volumes.

ff89d101e7 UI: Changes to Viewport Display UI of Volume Object and Fluid
- Density, interpolation and slicing options in Volume Object's
  Viewport Display are now not aligned to each other as they are not
  closely related.
- Changed the enum property for slicing ('Method') to a boolean
  property 'Slice' and added a sub-panel for slicing options under
  the 'Viewport Display' panel in Volume Object and Fluid for better
  clarity.
- Renamed `axis_slice_method` to `use_slice` in the python API for
  Volume Object and Fluid.

f137022f99 Liquid Simulation Display Options (GSoC 2020)
All the changes made in the branch `soc-2020-fluid-tools` are included in this patch.

**Major changes:**

=== Viewport Display ===

- //Raw voxel display// or //closest (nearest-neighbor)// interpolation for displaying the underlying voxel data of the simulation grids more clearly.
- An option to display //gridlines// when the slicing method is //single//.

==== Grid Display ====

- Visualization for flags, pressure and level-set representation grids with a fixed color coding based on Manta GUI.

==== Vector Display ====

- //**M**arker **A**nd **C**ell// grid visualization options for vector grids like velocity or external forces.
- Made vector display options available for external forces.

==== Coloring options for //gridlines// ====

- Range highlighting and cell filtering options for displaying the simulation grid data more precisely.
- Color gridlines with flags.

- Also, made slicing and interpolation options available for Volume Object.

internally. Drawing and rendering code will follow in another commit.

Hair and PointCloud object types are hidden behind a WITH_NEW_OBJECT_TYPES
build option. These are unfinished, and included only to make it easier to
cooperate on development in the future and avoid tricky merges.
