Allow using faders with a square form factor in horizontal orientation, especially when the widget's width and height are equal.

Currently, faders placed in a perfect square container always behave vertically. This limits design flexibility, particularly when trying to create compact and symmetrical layouts where horizontal operation would be preferred.

– Enable the option to define orientation (horizontal or vertical) independently of aspect ratio

– Alternatively, automatically set fader direction based on drag direction or allow defining direction explicitly in settings

– Allow locking direction to prevent accidental axis changes

– More intuitive and flexible interface design

– Better compatibility with square UI layouts

– Enables new creative control surface designs

– Aligns with user expectations from other DAWs or controller apps
