Visualizer

[Doralitze]

The following issues still need to be resolved:

• Fix issue that W channel is not used in RGBW mode
• Fix issue that directly looking into a beam does not render any light. A lense flare is not required, just a flat texture providing the current color
• Fix behavior of dimmer channel
• Load max movement angles from fixture definitions.
• Refactor source code to implement separation of concerns (for example one should have different classes for different fixture renderers
• Add setting (General) to show file to load specified stage file automatically. @Doralitze will take care of this.
• Remove default stage file from source tree.

Remaining issues will be addressed in future work.

[Doralitze]

• Regarding refactoring: model/stage.py should be a package with classes from that file being in their own files.
• resource/data/stage.yaml should be removed.
• stage_editor_widget must be splitted into multiple files as well.
• In addition, the GL control logic and side bar widgets in stage_editor_widget should be separated.
• The shaders in stage_gl_widget.py should be separate files in the source tree.
• The model loading should be moved from stage_gl_widget.py to a separate class and file.
• The methods _traverse_gltf and _upload_vao also belongs to the 3D model class.
• A visualizer fixture needs to have its own class with capability mixins (for example can_move or emits_light) to ensure one can add fixtures with different traits (For example an LED bar which cannot move but has many pixels in its matrix) later on.
• Fix ruff issues

After each change, functionality must be tested in order to avoid regression.
After all of this is addressed, a second round of refactoring might be in order.
