what exactly is this. Is it just the common places thingy to the left of explorer, or does it also include things like the background window images for special folders, or the shutdown and logoff dialogues.

why:
I made a windowblinds skin (woot! ) and I am not sure whether to check that it supports shellstyles or not. The bars in the common place thingy are skinned and the backround has corresponding colors, but the buttons aren't skinned because the standard ones look very good with it. I didn't include the backround images for special folders because I couldn't figure out how to make them work and I personally don't like them. I did skin the shutdown and logoff dialogues along with those buttons. Please enlighten me.
