> With dark color schemes the previews of the text styles are usually unusable. Reason is that the usual document text colors are dark and made for a white paper background, but for the comboboxes and the listviews with the styles the UI background is used, not the one of the document. This is inconsistent with the preview area of the stylemanager, where a white background is used, not the UI one.

Pointers welcome. That could also be used to control the background of the preview box in the stylemanager, which is currently hardcoded to white. So at least this patch makes all previews consistent.
