You may want to use "cleave" here, to get something like (untested):
: hello-cairo ( -- )
{ 100 100 }
[
{
[ T{ rgba f 0 0 0 1 } set-source-color ]
[ 0 0 cairo_move_to ]
[ 100 100 cairo_line_to ]
[ 100 0 cairo_move_to ]
[ 0 100 cairo_line_to ]
[ 20 cairo_set_line_width ]
[ cairo_stroke ]
[ 0 0 50 50 cairo_rectangle ]
[ T{ rgba f 1 0 0 0.8 } set-source-color ]
[ cairo_fill ]
[ 0 50 50 50 cairo_rectangle ]
[ T{ rgba f 0 1 0 0.6 } set-source-color ]
[ cairo_fill ]
[ 50 0 50 50 cairo_rectangle ]
[ T{ rgba f 0 0 1 0.4 } set-source-color ]
[ cairo_fill ]
} cleave
] make-png-image drop ;
