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.
