* 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.

* compton: 0.1_beta2.5 -> 6.2
Drop the legacy, unmaintained version and use the fork for real.
On AMD hardware with Mesa 18, compton renders some colours incorrectly
when using the glx backend. This patch sets an environmental variable
for compton so colours are rendered correctly.
Topical bug: <https://bugs.freedesktop.org/show_bug.cgi?id=104597>
While systemd suggests using the pre-defined graphical-session user
target, I found that this interface is difficult to use. Additionally,
no other major distribution, even in their unstable versions, currently
use this mechanism.
The window or desktop manager is supposed to run in a systemd user service
which activates graphical-session.target and the user services that are
binding to this target. The issue is that we can't elegantly pass the
xsession environment to the window manager session, in particular
whereas the PassEnvironment option does work for DISPLAY, it for some
mysterious reason won't for PATH.
This commit implements a new graphical user target that works just like
default.target. Services which should be run in a graphical session just
need to declare wantedBy graphical.target. The graphical target will be
activated in the xsession before executing the window or display manager.
Fixes #17858.
