XFCE/XFWM4: darker & black version not reflected, accent color not shown & rimless not rimless

[mseveritt]

Dear Vince, in XFCE 4.16, there seems to be issues with XFWM4.

• The color versions darker & black is not reflected: (appeared with --tweaks darker & --tweaks nord darker, similar effect with --tweaks black)

• If an accent color is used (e.g. -t blue), the rim is still in white and also the close button is white when hovered:

• If rimless is used, there is still a rim:

Is it possible to fix that? Many thanks in advance also for the development of this beautiful theme of yours.
