GC gc;

Description
Xlib normally defers sending changes to the components of a GC to the server until a graphics function is actually called with that GC.
This permits batching of component changes into a single server request. In some circumstances, however, it may be necessary for the
client to explicitly force sending of the changes to the server. An example might be when a protocol extension uses the GC indirectly, in
such a way that the extension interface cannot know what GC will be used. In a case like this, the extension library could use XFlushGC()
to force any cached changes to the GC it will use to be flushed to the server.
