The UV color changed after these changes.

This partially reverts commits rBAfdebdd681f0b, rBA563ea27eb1a8 and rBAb56a6acb9f4f.

And fixes T101134.

We still need to find an appropriate way to replace `glEnable(GL_LINE_SMOOTH)`.

The issue was introduced in cf773d42 and vis caused
by a lack of class unregister.

Fixes regression tests, as well as usecase when a user
toggles the addon off and on again.

* Move into its own sub-panel inside the Keyframes panel

* Use column layout for Wireframe Toggle.
* Move into its own sub-panel.

This data-block indicator is no longer needed now that the Node Editor
has a context path overlay introduced in Blender 3.0

Since 2.8 the Shader Editor has a popover with a UIList of all materials,
much more complete than the dropdown implementation in Amaranth.

Good to see Amaranth features being replaced by built-in ones in Blender :D

* AMTH_NODE_OT_show_active_node_image in Node Editor
* AMTH_VIEW3D_OT_render_border_camera in 3D Viewport

FBX exporter code was only supporting "Face Corner - Byte Color"
attribute type, using the deprecated Mesh.vertex_colors API. Update
the to use the new attributes API, and to handle all the attribute
combinations.

An option to pick between sRGB (default, matches current behavior),
Linear (requested in T82847) or None (don't export/import any color
attributes) has been added to the exporter and the importer.

Small micro optimization

Add more features for Material and ImageTexture settings:
1. The ability to change Interpolation Mode of the texture (linear, closest, cubic, smart).
   Before there was only linear as default.
2. The ability to change the extension parameter.
3. The ability to change a Blend Mode (Blend, Clip, Hashed).
   Before there was only Blend (or Opaque if "Use Alpha" is unchecked) as default.
4. In "Alpha Blend" case, added the "Show Backface" checkbox.
5. The ability to change the Shadow Mode (Clip, Hashed, Opaque) or disable casting shadows.
   Before there was only "Alpha Clip" as default.
6. The ability to enable Backface Culling.

Reworked:
1. Compositing Nodes, Material Settings and Texture Settings are in different layouts now.
2. "Use Alpha" checkbox has moved from "Texture Setting" to "Material Settings".

"Add/Remove nested from selection" was inverting the selection for the
branch instead of adding or removing.  This fixes it to behave similarly
to toggling nested RTOs.

Bring back the auto-generated block delimiters
Also: sort unregister() in reverse order to register()

Revert part of rBAad1966474ed2 in nw_check() which was giving no benefit
afaict (and instead tried to access space.node_tree for Spaces other
than the Node Editor, spamming the console with errors).
