bump version to 6.3

I noticed that a non-trivial amount of dwm's work on my machine was from
drw_text, which seemed weird, because I have the bar disabled and we
only use drw_text as part of bar drawing.

Looking more closely, I realised that while we use m->showbar when
updating the monitor bar margins, but don't skip actually drawing the
bar if it is hidden. This patch skips drawing it entirely if that is the
case.

On my machine, this takes 10% of dwm's on-CPU time, primarily from
restack() and focus().

When the bar is toggled on again, the X server will generate an Expose
event, and we'll redraw the bar as normal as part of expose().

-18:17 < Biolunar> when i change my resolution in dwm (to a smaller one) and then back to the native, the top bar is not repainted. that's since 5.7.2, in 5.6 it worked fine

-voltaic reports this:
-
-When I use two monitors, one larger in resolution than the other, the
-bar is drawn using the smaller x-dimension on both screens. I think
-what's happening is that there are two bars drawn, but the short bar
-is always on top of the long bar such that I can't see the information
-under the short bar. If I switch to the small screen, hide the short
-bar, and then switch to the large screen, the long bar is drawn
-correctly.
-
-A similar problem occurs when I have started dwm on a small resolution
-monitor (laptop screen) and then I switch to a large external display.
-When I do this, the bar itself is drawn for the original smaller
-resolution, but the information to be printed on the bar is
-right-aligned for a longer bar. So what I see is a bar that has the
-right hand side of it cut-off. See attached screenshot.
-
-I am using standard options for xrandr such as --output VGA1 --auto, etc.
