SVN commit 813283 by mart:

new BackgroundHint:
TranslucentBackground, now used by folder view.
when an applet has TranslucentBackground set, it loads
"widgets/tranlucentbackground" as its own background
when that svg does not exists in theh them it falls back to
"widgets/background" instead of translucentbackground of the default
theme
