Daniel Schaefer eccb90a2d9 compton: 0.1_beta2.5 -> 6.2 (#61681)
* compton-git: 5.1-rc2 -> 6.2

vsync is now a boolean option, see:
https://github.com/yshui/compton/pull/130

menu-opacity is deprecated and there's a warning that says:
Please use the wintype option `opacity` of `popup_menu` and
`dropdown_menu` instead.

* nixos/compton: Keep vSync option backwards compatible

The new upstream option tries to make the best choice for the user.
Therefore the behaviour should stay the same with this backwards
compatibility patch.

* compton-git: Remove DRM option

It's deprecated and shouldn't be used.
https://github.com/yshui/compton/pull/130/files#r285505456

* compton-git: Remove new_backends option

Was removed in "Let old/new backends co-exist"
b0c5db9f5aa500dc3568cc6fe68493df98794d4d

* compton: 0.1_beta2.5 -> 6.2

Drop the legacy, unmaintained version and use the fork for real.
