General Improvements (2023.3)

Here are the scripting, raytracing, VRED Go, and UV Editor improvements that can be found in 2023.3.

Scripting

Added an example for how to open the VRED terminal from the VR Menu. See the Menu with Show Terminal button example.
Added examples for how to render one stillframe image per viewpoint of a camera track and how to render an image sequence for camera track animation (flying to all viewpoints). See Rendering Camera Tracks.
Made the Script Editor dockable and it can now stay in front of the screen.
Added a command to convert a node to a switch.
Added support of MaterialNode to create MaterialGroup in the Scenegraph.
Added commands for Copy Transformation and Paste Transformation.

Added Denoise Alpha to Edit > Preferences > Rendering > Render Settings > Antialiasing and Render Settings > Antialiasing for toggling of alpha channel denoising and filtering of sampled environment caustics. When disabled, the alpha channel is copied from the input image without applying the denoiser, which increases render performance. We also added the Python command, setDenoiseAlpha(true/false).
Improved environment map quality on materials with low roughness in Full Global Illumination.
Improved magnification of anisotropic filtered textures.
Fixed incorrect IBL results when the lightsource is close to the pole.
