Jonathan Corwin has proposed merging lp:~j-corwin/openlp/transparent into
lp:openlp.
Requested reviews:
OpenLP Core (openlp-core)
For more details, see:
https://code.launchpad.net/~j-corwin/openlp/transparent/+merge/87530
This change allows a Theme to have a Transparent background (again) so that the
desktop or any other applications can be viewed behind the lyrics.
Note it wouldn't work on non-composite Linux desktops so this would need to be
documented.
I made a change to the routine that grabs the preview of the display for the
slidecontrollers and theme wizard since the old way didn't work with
transparency. I don't know if this has any side effects, I didn't spot any at
my end but any testing would be appreciated.
