User-defined compiler control symbol

{{fbdoc item="syntax"}}##
	#define FB_NO_GFXLIB
##
{{fbdoc item="desc"}}
	Defining ##FB_NO_GFXLIB## tells the compiler not to treat selected graphics-library command words as built-in gfxlib command keywords.
	
	This is useful in larger programs or libraries that do not use the legacy graphics command surface and need names such as ##Screen##, ##Paint##, or ##Window## to be available as normal identifiers.
	
	The affected gfxlib command words are ##PSET##, ##PRESET##, ##POINT##, ##CIRCLE##, ##WINDOW##, ##PALETTE##, ##SCREEN##, ##SCREENQB##, ##PAINT##, ##DRAW##, and ##IMAGECREATE##.
	
	##FB_NO_GFXLIB## affects parsing only after the symbol has been defined.  It does not remove libraries that are explicitly requested through other code, and it does not change the behavior of already-parsed source.
