The following code locations,  including the varient named method table slots.

Headers/Additions/GNUstepGUI/GSMethodTable.h:111:  void (*GSShowText__)
Headers/AppKit/DPSOperators.h:165:GSShowText(GSCTXT *ctxt, const char * string, 
size_t length)
Headers/AppKit/DPSOperators.h:690:GSShowText(GSCTXT *ctxt, const char * string, 
size_t length)
Headers/AppKit/DPSOperators.h:692:  (ctxt->methods->GSShowText__)
Headers/AppKit/DPSOperators.h:693:    (ctxt, @selector(GSShowText: :), string, 
length);
Headers/AppKit/NSGraphicsContext.h:308:- (void) GSShowText: (const char 
*)string : (size_t) length;
Source/NSGraphicsContext.m:559:  methodTable.GSShowText__ =
Source/NSGraphicsContext.m:560:    GET_IMP(@selector(GSShowText::));
Source/NSGraphicsContext.m:1069:- (void) GSShowText: (const char *)string : 
(size_t) length

Headers/gsc/GSGStateOps.h:75:- (void) GSShowText: (const char *)string : 
(size_t) length;
Source/cairo/CairoGState.m:416:- (void) GSShowText: (const char *)string : 
(size_t)length
Source/gsc/GSContext.m:420:- (void) GSShowText: (const char *)string : (size_t) 
length
Source/gsc/GSContext.m:422:  [gstate GSShowText: string : length];
Source/gsc/GSGState.m:626:- (void) GSShowText: (const char *)string : (size_t) 
length
Source/gsc/GSStreamContext.m:286:- (void) GSShowText: (const char *)string : 
(size_t)length



Also the same applies to the similarly named Text methods in the method table 
located alongside GSShowText:

GSGetTextPosition
GSSetTextPosition
GSSetTextDrawingMode  (and the GSTextDrawingMode enum typedef)
GSGetTextCTM
GSSetTextCTM
GSSetCharacterSpacing
GSSetFontSize

There are few or no backend specific implementations,  and no gui calls;
so do they actually serve a useful purpose?

The comments in NSGraphicsContext could be read as them having some future use 
wrt
to implementing Quartz.  But I guess not while still bearing the GS prefix.
