animation: add animation_opacity_min, for reduce flicker

Thank you for your contributions!

The blacklist code looks great.

The code for the minimum opacity looks good too, but I question its inclusion. ~Why do you think it is necessary/desirable? It seems to me that it is a workaround for #19, which isn't necessarily bad, but if that's the case, it does not tackle the root cause at all -- and that's bad.~ Sorry, I didn't properly read your last message. What do you mean by "flicker"? (The point about the root cause probably still stands, though.)

About flicker, I can show you gif.

// Only animate opacity here if we are resizing
// a transparent window
process_window_for_painting(ps, w, w->win_image,
    w->opacity >= 1 ? 1.0 : w->animation_progress,
    &reg_bound, &reg_visible,
    &reg_paint, &reg_paint_in_bound);

// Only do this if size changes as otherwise moving 
// transparent windows will flicker and if you just
// move so slightly they will keep flickering
if (resizing) {
         process_window_for_painting(ps, w, w->old_win_image,
     1.0 - w->animation_progress,
     &reg_bound, &reg_visible,
    &reg_paint, &reg_paint_in_bound);
}

When window be moving slightly, animation_progress always loop between 0 to 1. (xserver continuously send moving requests)

Update? This is a really important piece as some programs are pretty much unusable with animations.
