Implement standalone options to separately reverse vertical and horizontal scrolling [enhancement]

[yctay]

Description

When reverse scrolling is selected, both vertical and horizontal scrolling are affected.

On my mouse (Logitech MX Master 3), vertical and horizontal scrolling are opposites, which is to say:

With reverse scrolling enabled:

• Vertical scrolling is reversed.
• Horizontal scrolling is normal.

With reverse scrolling enabled:

• Vertical scrolling is normal.
• Horizontal scrolling is reversed.

Proposal

Implement standalone options to separately reverse vertical and horizontal scrolling.
