Used to indicate which fields in the #GdkWindowAttr struct should be honored.
For example, if you filled in the “cursor” and “x” fields of #GdkWindowAttr,
pass “GDK_WA_X | GDK_WA_CURSOR” to gdk_window_new(). Fields in
#GdkWindowAttr not covered by a bit in this enum are required; for example,
the width/``height,wclass, and window_type fields are required, they have
no corresponding flag in #GdkWindowAttributesType.
