Changing blurEnabled and opacity for a single instance of PopupDialog

[jeffduet]

I have a need to change PopupDialogOverlayView.blurEnabled and .opacity for a single instance of PopupDialog, and not for others. While I can change PopupDialogOverlayView.appearance() before and after I use the dialog, that is a bit hacky and I would like to figure out the cleanest way to change these parameters for a single instance.

If this is not possible now then I would like to have this feature added if possible.
