Modified Files:
Ecore_X.h ecore_x.c ecore_x_private.h ecore_x_window_prop.c
Log Message:
Add support for the proposed _NET_WM_WINDOW_OPACITY window manager hint.
At the moment does nothing useful unless you're running kdrive with a
specially patched version of Metacity ... but I just felt like putting it
in there anyways for later.
A little bit of the upcoming selections code leaked in with one of the
files in this commit.
