Yes, it will be compiled automatically.

So, for modern linux distributions, gnuplot will depend on more packages 
then until now. Or some "optimized" distributions could even distribute 
both gnuplot/X11 and gnuplot/X11+WX.

it is easier to modify $HOME/.gnuplot

Yes, wxt has nicer drawings.

I just try to measure it (averaged over 10 times of
plot 'out.gpbin' binary with image):

# Results:  512^2 image: x11 takes 0.25 second, wxt 0.5 seconds
# Results: 1024^2 image: x11 takes 0.8  second, wxt 1.4 seconds
# Results: 2048^2 image: x11 takes 3.2  second, wxt 5.0 seconds

(I use it for images mainly under Octave.)

I think Timothee said that's the speed of pango which will be optimized 
later on.

yes

Because he can choose?
