// normally we would only draw stuff in subitem stages
// this broke when we tried drawing focus rects in postpaint; the drawing either kept getting wiped or overdrawn, mouse hovering had something to do with it, and none of the "solutions" to this or similar problems on the internet worked
// so now we do everything in the item prepaint stage
// TODO consider switching to full-on owner draw
// TODO only compute the background brushes once?
