Text from original patch:
Using pango markup for status text
Use a single font. Removed some code utf8 code from drw.
Created for pango 1.44. Older versions might not have getter
for font height, ascent + descent can be used instead.
All texts are rendered with pango but only status is with
markup. Increased stext size (in case a lot of markup is used).
MIN/MAX is already defined (didn't redefine them).
Text width calculations when using status2d strings resulted in
statuscmd button placement calculations to be way off. Fixed by
introducing a separate function status2dtextlength to get an
approximate correct text width.
