Yes. It appears to me to offer a mechanism to minimise dependencies in 
MythMusic.

If, for example, it was desired to add two additional visualisations to 
MythMusic then that would most likely correspondingly add two additional 
dependencies (on the visualisation libraries in question) where as using 
libvisual offers the ability to add a single additional dependency (on 
libvisual) yet still provide two, or more, additional visualisations.

The vast majority of the work in producing these patches was involved in 
modifying MythMusic to enumerate the available visualisations and modifying 
MythTV to provide a mechanism of presenting a multi-select configuration 
widget.

Sorry it took so long, but as always, it was more work than I had originally 
imagined ;-)
