* 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.
