Vampire: The Masquerade - Redemption intro video scaled

When fullscreen resolution is set to something low and different from aspect
ratio of the monitor, winewayland scales it up, but positions it on the left,
rather than in the middle of the screen and leaves the mismatching area
transparent.

This happened for example in the intro video of Vampire: The Masquerade -
Redemption. The video is 640x346 and my screen is 2560x1440.

See attached screenshot for how it looks.

It would be better if the scaled window was positioned in the middle, with some
black bands for areas that are caused by mismatch in aspect ratio.

Even better if this behavior could be configurable, i.e. where to position,
what to use for bands, like transparent, solid color / what color, etc.
