Constant xcb::xproto::CW_BACK_PIXMAP

pub const CW_BACK_PIXMAP: Cw

Overrides the default background-pixmap. The background pixmap and window must have the same root and same depth. Any size pixmap can be used, although some sizes may be faster than others.

If XCB_BACK_PIXMAP_NONE is specified, the window has no defined background. The server may fill the contents with the previous screen contents or with contents of its own choosing.

If XCB_BACK_PIXMAP_PARENT_RELATIVE is specified, the parent's background is used, but the window must have the same depth as the parent (or a Match error results). The parent's background is tracked, and the current version is used each time the window background is required.
