__FB_GFXLIB3__
Intrinsic define set when gfxlib3 is selected.
#ifdef __FB_GFXLIB3__
The compiler defines __FB_GFXLIB3__ when the -gfx3 option selects the opt-in gfxlib3 runtime. A source file can make the same selection by defining the symbol before it first includes fbgfx.bi. Including fbgfx3.bi also defines it before loading the common graphics declarations.
The symbol is defined without a value. Test it with ifdef or defined() instead of treating it as a numeric expression.
