Renamed variables in the MaskSetMode, MaskClearMode, MaskToggleMode, and MaskHasMode functions as well as within ModesFromFlags function to improve clarity and readability of their functionality. These changes ensure that the purpose of each variable is immediately identifiable, enhancing maintainability of the codebase.
