[feature request] visual filters

[ghost]

hi, this is in no way an actual request/demand,
but more of an early stage idea,
gracefully "dumped" here for some creative brain storming.. (so feel free to close it..).

There is a growing trend of YouTubers making poor (not to mention annoying) use of the screen.

here is an example:

I though some time now of some visual filters,
implementation can be a div, solid-filled color (user may select the color to match the video's actual background), placed in top-most z-index order (or at least above the playing-video layer),
it can stay there for a specific time, similar to how all the existing filter already work (but obviously it also requires holding an additional placement-data, top-left, height, width or something like that).

it is also similar to the way the YT-player implements over-the-video banners.

here is quick and dirty "mock" (using some graphic editor):

Video_2022-01-12_213225.wmv_compatibility.mp4

---

a possible extended visual filter can stretch the video,
from a point, to fill the current video container.

Video_2022-01-12_213402.wmv_compatibility.mp4

stored data would probably require the square measurements, and starting-ending times again.
