[Bug 5382] Add QT/GTK Integration

[WineHQ Bugzilla]

--- Comment #33 from Bamm Gabriana  ---
Let me try again: What I meant was that the default prefix is the only one that
I can assume to exist; all other prefixes are on a path that is arbitrarily
decided by the user.

Hence, if I automate writing system colors into wine when user change themes,
then $HOME/.wine is the only one that I can automate.

If user creates a new wine prefix for an app he installs, then user would have
to manually run the script on that prefix:

WINEPREFIX=/path/to/prefix /path/to/script

to update its system colors before he runs his app. This manual act by the user
is what I want to avoid.

If someone runs a program in wine, the program should appear in the current
theme colors, without end user having to do anything.
