Handling bkgset() and friends

When bkgdset() is called the "background is combined (OR'ed) with all non-blank
characters that are written into the window with waddch."  Unfortunately, there is no CSI that corresponds to this operation.  When I honor CSI ED and similar sequences how would I know what color to fill the cell with?  Looking at the sequences emitted by ncurses, it *seems* like it might be reasonable to assume that the foreground and background colors that are set just before CSI ED is called should be regarded as the default fg / bg combination.  Is that a inference to run with?
