Options that specify how to scale the panel area when the aspect ratio of the current screen resolution does not match the reference resolution. See PanelSettings.screenMatchMode.
| MatchWidthOrHeight | Scales the panel area using width, height, or a mix of the two as a reference. | 
| Shrink | Crops the panel area horizontally or vertically so the panel size never exceeds the reference resolution. | 
| Expand | Expand the panel area horizontally or vertically so the panel size is never smaller than the reference resolution. |
