The XtGetGC function returns
a sharable, read-only GC. The parameters to this function are the same as
those for XCreateGC except that a widget is passed instead of a display.
XtGetGC shares only GCs in which all values in the GC returned by XCreateGC
are the same. In particular, it does not use the value_mask provided to
determine which fields of the GC a widget considers relevant. The value_mask
is used only to tell the server which fields should be filled in with widget
data and which it should fill in with default values. For further information
about value_mask and values, see XCreateGC in the Xlib - C Language X
Interface.
The XtReleaseGC function deallocate the specified shared GC.
