XSetArcMode can generate BadAlloc, BadGC, and BadValue errors.
The XSetSubwindowMode function sets the subwindow mode in the specified
GC.
XSetSubwindowMode can generate BadAlloc, BadGC, and BadValue errors.
The XSetGraphicsExposures function sets the graphics-exposures flag in

DIAGNOSTICS
BadAlloc The server failed to allocate the requested resource or server
memory.
BadGC A value for a GContext argument does not name a defined GCon-
text.
BadValue Some numeric value falls outside the range of values accepted
by the request. Unless a specific range is specified for an
argument, the full range defined by the argument's type is ac-
cepted. Any argument defined as a set of alternatives can
generate this error.
