[Feature request]: Custom LED Zones

[raybantracing]

Is your feature request related to a problem? Please describe

Currently, in some games with large and persistent overlays (e.g., MOBAs or similar), the Ambilight effect on the bottom of the screen remains fixed to the overlay color.

There are many other games besides MOBAs that have this issue, for example, any game with a minimap that is always visible on the screen.

Describe the solution you'd like

It would be very useful to be able to freely move the LED capture zones directly on the test image. This would allow users to avoid overlay areas and capture only the actual gameplay area.

Even games very different from MOBAs, like Battlefield 6 for example, would benefit from the ability to move and resize the LED capture zones.

Even Path of Exile 2 has same issue. I have a blue and red halo on the bottom corner of my desk with it.

This is something I've been working on for a while… more info later.
