This is because the position and width of the
text is calculated as a float. So given
// The "real" float bounds
Rectangle2D r2d = ctx.getGraphicsNode(t1).getBounds();
double x0 = r2d.getX();
double x1 = x0 + r2d.getWidth();
int intWidth = ceil(x1)-floor(x0);
This is not the same as floor(r2d.getWidth())
for obvious reasons.

Neither the correct width of t1 is the
double precision value returned by r2d.getWidth();
the rect.width() is a 'safe' width but may be
off by up to 2! counts.
