--- * textStyle - an optional table, defaults to `nil`, specifying that a string message should be converted to an `hs.styledtext` object using the style elements specified in this table. This table should conform to the key-value pairs as described in the documentation for the `hs.styledtext` module. If this table does not contain a `font` key-value pair, one will be constructed from the `textFont` and `textSize` keys (or their defaults); likewise, if this table does not contain a `color` key-value pair, one will be constructed from the `textColor` key (or its default).
--- * padding - the number of pixels to reserve around each side of the text and/or image, defaults to textSize/2
--- * atScreenEdge - 0: screen center (default); 1: top edge; 2: bottom edge . Note when atScreenEdge>0, the latest alert will overlay above the previous ones if multiple alerts visible on same edge; and when atScreenEdge=0, latest alert will show below previous visible ones without overlap.
--- * atScreenOffset - a table specifying x and y offset for atScreenEdge, defaults to x = 0, y = 0
--- * fadeInDuration - a number in seconds specifying the fade in duration of the alert, defaults to 0.15
--- * fadeOutDuration - a number in seconds specifying the fade out duration of the alert, defaults to 0.15
