 		<member name="display/window/stretch/scale_mode" type="String" setter="" getter="" default="&quot;fractional&quot;">
 			The policy to use to determine the final scale factor for 2D elements. This affects how [member display/window/stretch/scale] is applied, in addition to the automatic scale factor determined by [member display/window/stretch/mode].
+			[b]"fractional"[/b]: The scale factor will not be modified.
+			[b]"integer"[/b]: The scale factor will be floored to an integer value, which means that the screen size will always be an integer multiple of the base viewport size. This provides a crisp pixel art appearance.
+			[b]Note:[/b] When using integer scaling with a stretch mode, resizing the window to be smaller than the base viewport size will clip the contents. Consider preventing that by setting [member Window.min_size] to the same value as the base viewport size defined in [member display/window/size/viewport_width] and [member display/window/size/viewport_height].
