Colors are often thought of as being 4 values that make up that can make any color.
But that is of course too limited. In C we didn’t spend time to annotate what we meant
when using colors.
Recently `BLI_color.hh` was made to facilitate color structures in CPP. CPP has possibilities to
enforce annotating structures during compilation and can adds conversions between them using
function overloading and explicit constructors.
The storage structs can hold 4 channels (r, g, b and a).
Usage:
Convert a theme byte color to a linearrgb premultiplied.
```
ColorTheme4b theme_color;
ColorSceneLinear4f<eAlpha::Premultiplied> linearrgb_color =
BLI_color_convert_to_scene_linear(theme_color).premultiply_alpha();
```
The API is structured to make most use of inlining. Most notable are space
conversions done via `BLI_color_convert_to*` functions.
- Conversions between spaces (theme <=> scene linear) should always be done by
invoking the `BLI_color_convert_to*` methods.
- Encoding colors (compressing to store colors inside a less precision storage)
should be done by invoking the `encode` and `decode` methods.
- Changing alpha association should be done by invoking `premultiply_alpha` or
`unpremultiply_alpha` methods.
# Encoding.
Color encoding is used to store colors with less precision as in using `uint8_t` in
stead of `float`. This encoding is supported for `eSpace::SceneLinear`.
To make this clear to the developer the `eSpace::SceneLinearByteEncoded`
space is added.
# Precision
Colors can be stored using `uint8_t` or `float` colors. The conversion
between the two precisions are available as methods. (`to_4b` and
`to_4f`).
# Alpha conversion
Alpha conversion is only supported in SceneLinear space.
Extending:
- This file can be extended with `ColorHex/Hsl/Hsv` for different representations
of rgb based colors. `ColorHsl4f<eSpace::SceneLinear, eAlpha::Premultiplied>`
- Add non RGB spaces/storages ColorXyz.

Issue is that due to the strange definition of render in grease pencil
(meaning should be rendered similar to rendering). This included normal
viewport rendering in OB_RENDER and OpenGL render in OB_RENDER.
For other rendering modes the overlay vertex opacity would be used. This
patch sets this value to 1 when rendering via a scene strip override.
NOTE: that this isn't a good solution as I expect that users want to use
the opacity of the Grease pencil object. Perhaps the GPencil team has a
better solution for it.
Tool settings for sequencer were not initialized, which caused crash
when adding strips.
There was fix for same issue in versioning rB0f81dafe6cec, but
subversion was not bumped, so files with uninitialized tool settings
may still exist.
Add `SEQ_tool_settings_get()` accessor function that will initialize

This fallback is an old hack.
It is difficult to have an orientation convention when several random
factors determine which one should be used.
In this case, to "fix" the problem, a new behavior had to be implemented.
Now the redo when moving the camera in `Camera View` has the default

When sound strip is above another strip such as movie strip, it prevents
from rendering movie strip.
This bug was introduced in 0b7744f4da. Function `must_render_strip()`
checks if there is any strip with `SEQ_BLEND_REPLACE` blending and
considers this strip as lowest strip in stack. Sound strips do have this
blend mode set, which caused the bug.
Remove all sound strips and muted strips from stack collection before
checking with `must_render_strip()` function

The CoW copy of the node group was not updated correctly after it
changed. Arguably, tagging the node tree could also be part of
`ntreeUpdateTree` (which needs to be called after changes to the
node tree anyway). However, there are many instances where the
depsgraph is tagged explicitly after `ntreeUpdateTree` is called,
so it should be fine here as well. This is similar to what is done
in `snode_dag_update`.

Accessing data through RNA should never implicitely create it. Objects'

This data (the force fields) are expected to always be there, but they

Root of the issue was actually hidden deep in depsgraph itself: it would
not properly update all of its COW IDs using a datablock when depsgraph
decides to evaluate or un-evaluate it.
This would lead to evaluated IDs pointing to either:
- orig IDs when there was an evaluated version of those (annoying bug,
but not a crashing one).
- old address of previously evaluated IDs that no longer exists in the
depsgraph (causing the crash from the report e.g.).
This commit adds an extra step at the end of nodes building, that goes
over all of already existing IDs in the depsgraph to check whether they
do one of the two things above, and tag them for COW update if so.
NOTE: This only affects depsgraph (re-)building, not its evaluation.
This remains consistent with the fact that operations that may change
the depsgraph content (like Collection exclusion etc.) need to trigger a
rebuild.
NOTE: Performances: Worst case scenarii, like (un-)excluding a whole
character collection in a production file, lead to 5% to 10% extra
processing time in depsgraph building. Most of it comming from extra COW
processing (in depsgraph's update in `build_step_finalize`), the detection
loop itself only accounts for 1% to 2% of the whole building time.

Share the pointer with the original mesh instead, this matches behavior
of all other objects edit-mode data.
Duplicating the edit-mesh pointer makes updates to edit-mesh require
a COPY_ON_WRITE update, which is currently an expensive operation
(copying the entire mesh).
Notes:
- This change is from 802027f3f8
so the edit-meshes object pointer `BMEditMesh.ob` referenced the COW
version of the object. This pointer has since been removed, so the
copy is no longer needed.
- Having a separate edit-mesh pointer could be used so linked duplicates
could have their own generated meshes. For this to be supported,
many other changes would be needed: see D10920.

Since there is a special callback for assigning the name from the
search box, and the callback doesn't call an operator or something
else that would do an undo push, I think the solution is to do it
manually here.
Another option would be adding the button flag "UI_BUT_UNDO", which
isn't set by default for search buttons, but that gives us ugly names for
the undo steps, so an explicit push is better in this case.
