XSetFillRule() can generate BadAlloc, BadGC, and BadValue errors.

BadAlloc	The server failed to allocate the requested source or server memory.
BadGC	A value for a GContext argument does not name a defined GContext.
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 accepted. Any argument defined as a set of alternatives can generate this error.
