blendify 2.0.0 Release

This release, among other minor improvements, introduces a more flexible way of defining the material, more material presets, support for different rotation representations, improved light parsing, and fast rendering with the eevee engine to preview the result.

Some of the changes are not backward compatible with the previous version of blendify; the breaking changes are listed below:

Breaking changes

• Removed attach_blend_w_camera from Scene;
  now parsing is controlled via with_camera parameter in Scene.attach_blend()
• Removed PrinsipledMaterial, a mistyped name for PrincipledBSDFMaterial;
• Renamed the quaternion parameter in Positionable to rotation;
  rotation mode is now controlled via the rotation_mode parameter;
• To compress the repository, we have cleaned the history of modifications for big files (mostly gif), resulting in a new commit tree;
• Flipped texture reading row order in TextureColors to be compatible with FileTextureColors.

Summary of other changes and improvements:

Materials

• Implemented a flexible way to define new materials using shading nodes from Blender;
  This allowed us to implement a combination of materials, e.g., PrincipledBSDF with Wireframe on top;
• Added several presets for PrincipledBSDFMaterial to ease material creation (PlasticMaterial, MetalMaterial, and similar materials with wireframe on top);

Lights

• Implemented parsing of light sources to LightsCollection from .blend file (via Scene.attach_blend());
• Added set_background_light method to LightsCollection to set ambient lighting via world shading nodes in Blender;

Object manipulation

• Extended support for different rotation representations in Positionable objects;
  Now all common representations (quaternion, Euler angles, axis-angle, rotation matrix) are supported;
• Implemented look_at as a rotation mode for Positionable objects to ease camera positioning;

Other

• Unified .blend parsing logic for parsing with and without a camera;
• Implemented fast preview via eevee engine to allow for intermediate previews of the scene;
• Added plane primitive to ease implementing shadow catchers (code is provided in Example 7);
• Added pointcloud to textured mesh conversion function in blendify.utils;
• Updated the code to rely on Blender 3.6.0 LTS.
