//! The style every `DialogFrame` overlay is drawn in.
//!
//! **One style, every dialog.** The open dialog, the save dialog and the text editor are all the
//! framework's `DialogFrame`, and the cue that says which control holds the keyboard is the same in
//! all three (D3 of #189). Keeping it here is what stops the same six lines from being copied into
//! every overlay that arrives.
//!
//! **Every state that is not the pointer is a state**: the focused button and the pressed one are
//! both reversed, so pressing an `Ok` the keyboard is not on cannot look like a second kind of
//! focus. `hover` is cleared because a control under the pointer is not a state of the control.
