Engine is not stored in WorkSpaces. That defines the "context" engine, which
is used for the entire UI.
The engine used for the poll of nodes (add node menu, new nodes when "Use Nodes")
is obtained from context.
Introduce a ViewRender struct for viewport settings that are defined for
workspaces and scene. This struct will be populated with the hand-picked
settings that can be defined per workspace as per the 2.8 design.
* use_scene_settings
* properties editor: workshop + organize context path
Use Scene Settings
==================
For viewport drawing, Workspaces have an option to use the Scene render
settings (F12) instead of the viewport settings.
This way users can quickly preview the final render settings, engine and
View Layer. This will affect all the editors in that workspace, and it will be
clearly indicated in the top-bar.
Properties Editor: Add Workspace and organize context path
==========================================================
We now have the properties of:
Scene, Scene > Layer, Scene > World, Workspace
[Scene | Workspace] > Render Layer > Object
[Scene | Workspace] > Render Layer > Object > Data

Although this wasn't so obvious since it
only showed up for factory settings and in the preferences window.
Panel display order depends on registration order,
Sorry for the noise. On the bright side we no longer need to move
classes around to re-arrange panels.
This mostly affects physics panels. Any engines relying on
RenderEngine.use_game_engine flag to show/hide panels will need to be
updated. The COMPAT_ENGINES technique is how we usually deal with this.
One issue with use_game_engine is that I cannot find a way to set it; it
appears only the BGE can set it. This means (without this commit)
external RenderEngines cannot get rid of the default physics panels.
The RE_GAME flag (the C flag behind use_game_engine) is pretty hacky
and we should look into removing its usage where possible.
Notes:
* Did not touch to addons, that's up to the authors. ;)
* Did not removed any "name" field below lists. We might want to do this in some cases (less UI clutter), but probably not always, so will let maintainers of the related areas decide here.
It greatly helps getting rid of that "noise" that occurs if you use really steep objects (like cubes) as a brush. New default value is 1.0 which is just high enough to only get rid of the sharpest spikes, so if you want really smooth waves it's better use higher values.
This also seems to "fix" bug [#35413].
It introduces a new (py-extendable and registrable) RNA type, UIList (roughly similar to Panel one), which currently contains only "standard" list's scroll pos and size (but may be expended to include e.g. some filtering data, etc.). This now makes lists completely independent from Panels!
This UIList has a draw_item callback which allows to customize items' drawing from python, that all addons can now use. Incidentally, this also greatly simplifies the C code of this widget, as we do not code any "special case" here anymore!
To make all this work, other changes were also necessary:
* Now all buttons (uiBut struct) have a 'custom_data' void pointer, used currently to store the uiList struct associated with a given uiLayoutListBox.
* DynamicPaintSurface now exposes a new bool, use_color_preview (readonly), saying whether that surface has some 3D view preview data or not.
* UILayout class has now four new (static) functions, to get the actual icon of any RNA object (important e.g. with materials or textures), and to get an enum item's UI name, description and icon.
* UILayout's label() func now takes an optional 'icon_value' integer parameter, which if not zero will override the 'icon' one (mandatory to use "custom" icons as generated for material/texture/... previews).
Note: not sure whether we should add that one to all UILayout's prop funcs?
Note: will update addons using template list asap.

* Added per surface options "influence scale" and "radius scale" for tweaking brush settings individually for each surface.
* Added option to completely disable drying. This should be nice for indefinitely spreading paint etc.
* Improved paint mixing algorithm.
* "Paint effects" now work in relative mesh space instead of global. This means that effect speed remains same for identical shapes regardless of their size.
* Complete rewrite of "spread effect" algorithm. It now works much better in all test cases done. Old algo sometimes produced artifacts and stopped spreading too early.
* Adjustments / rewrite on some parts of dripping algorithm to make it work better with transparent paint.
* Added a new "color dry" setting. It can be used to define wetness level when paint colors start to shift to surface "background". Lower values can be useful to prevent spreading paint from becoming transparent as it dries, while higher (default) values give better results in general.
* Fix: If multiple displace/wave surfaces were used simultaneously, displace was applied using wrong normal.
Please note that due to these changes in "paint effects" system older save files may require some tweaking to match results from previous versions.

Rationale: the name was confusing and not always used consistently, and this
map itself is not something that can be layered, rather the map can be used
as texture coordinates in some layered setup.
The original intent was to indicate this contained more than just UV's, but
the game engine settings have already been moved out, and apparently users
didn't really get this from the name anyway.
if a value other than 1/0 was given it would use an uninitialized pointer too (compiler warning, review should pick up this stuff).
also renamed some RNA attrs:
output_name --> output_name_a
output_name2 --> output_name_b
do_output1 --> use_output_a
do_output2 --> use_output_b
do_smudge --> use_smudge
max_velocity --> velocity_max
* Renamed "Sharp" proximity falloff to "Constant".
* Added a new "Negate Volume" option for "Volume + Proximity" brush.
* Possible fix for random particle clipping errors.
* Code cleanup, changed some splits to row's, much nicer when you only use 2 properties in a row.
* if > elif
* Removed some duplicated code for an if/elif/else check
Did some minor separator() changes too.
* Redesigned alpha blending and paint drying algorithms. Now it gives much better results when using low brush alpha or when surface has initial color set.
* Fix: "Slow" dissolve/dry was scaled incorrect when using substeps. Also adjusted time to better match non-"slow" setting.
* Fixed possible issues when using image textured brush.
* Fix: particle brush panel was no longer visible since last commit.
* Adjusted default surface values.
* Some more code cleanup.
* Fix: Wave "timescale" also changed simulation behavior. Now different timescale values will lead to nearly identical results, just slower or faster.
* Added "Displace Factor" setting for vertex displace surfaces. You can use it to adjust final displace strength or use negative values to paint bumps.
* Added clamp/map value to wave image sequence output settings.
* RNA description tweaking.
* General code tweaking.
* Brush ui still had references to old "Non-Closed" property.
Note that old Dynamic Paint saves no longer work in carrot revisions 40411 and later due to new modifiers that were added into trunk. :(
