Comment 76 for bug 491521

Got it! :)
Thanks... unfortunately I'm a bit busy, but if you have a small patch
for murrine I will be glad to add a more complete rgba support

> Bug description:
> For Lucid, I'd like to get the new decorations feature integrated.  This patch adds support for doing client-side window decorations, which pulls in support for RGBA colormaps.
>
> The new decorations feature requires explicit support from a theme before it becomes active (it defaults to being disabled).  However, RGBA support is enabled by default and there is a chance for some fallout from this being added.
