We should always process all the X events in libxcb's queue with the
server grabbed, not just when we have `pending_updates` flag set.

This is the only way to make sure we always render with up-to-date
server states.

Remove the old fading machinary. As a side-effect, animation and time
based shaders are now unified.

This can be used to prevent another animation from interrupting the
current running animation.

This adds support for desktop switching animations by keeping track of _NET_CURRENT_DESKTOP atom on the root window. 

As far as I understand this atom is set by window managers and so if it changes we can know that it's a desktop switch happening. Unfortunately window manager may need to set this BEFORE hiding/showing windows so we can animate correctly, me personally using FluxBox and this quick change pijulius/fluxbox@83ee4db  makes it work just fine.

It adds the following animation triggers:
* workspace-out
* workspace-out-inverse
* workspace-in
* workspace-in-inverse

Unfortunately had to add inverse variables too as you may navigate to the next workspace from for e.g. 1st to 2nd but you may also go to 2nd from 1st and in that case the animations have to be totally different.

Here is a config example for switching workspace:

animations = ({
    triggers = ["workspace-out"];
    offset-y = {
        timing = "0.2s cubic-bezier(0.21, 0.02, 0.76, 0.36)";
        start = "0";
        end = "-window-height";
    };
    shadow-offset-y = "offset-y";
    opacity = {
        timing = "0.2s linear";
        start = "window-raw-opacity-before";
        end = "window-raw-opacity";
    };
    blur-opacity = "opacity";
    shadow-opacity = "opacity";
},
{
    triggers = ["workspace-out-inverse"];
    offset-y = {
        timing = "0.2s cubic-bezier(0.21, 0.02, 0.76, 0.36)";
        start = "0";
        end = "window-height + window-y";
    };
    shadow-offset-y = "offset-y";
    opacity = {
        timing = "0.2s linear";
        start = "window-raw-opacity-before";
        end = "window-raw-opacity";
    };
    blur-opacity = "opacity";
    shadow-opacity = "opacity";
},
{
    triggers = ["workspace-in"];
    offset-y = {
        timing = "0.2s cubic-bezier(0.24, 0.64, 0.79, 0.98)";
        start = "window-height + window-y";
        end = "0";
    };
    shadow-offset-y = "offset-y";
    opacity = {
        timing = "0.2s linear";
        start = "0";
        end = "window-raw-opacity";
    };
    blur-opacity = "opacity";
    shadow-opacity = "opacity";
},
{
    triggers = ["workspace-in-inverse"];
    offset-y = {
        timing = "0.2s cubic-bezier(0.24, 0.64, 0.79, 0.98)";
        start = "-window-height";
        end = "0";
    };
    shadow-offset-y = "offset-y";
    opacity = {
        timing = "0.2s linear";
        start = "0";
        end = "window-raw-opacity";
    };
    blur-opacity = "opacity";
    shadow-opacity = "opacity";
})
