 				Sets a custom mouse cursor image for the given [param shape]. This means the user's operating system and mouse cursor theme will no longer influence the mouse cursor's appearance.
 				[param cursor] can be either a [Texture2D] or an [Image], and it should not be larger than 256×256 to display correctly. Optionally, [param hotspot] can be set to offset the image's position relative to the click point. By default, [param hotspot] is set to the top-left corner of the image. See also [method cursor_set_shape].
+				[b]Note:[/b] On Web, calling this method every frame can cause the cursor to flicker.
