This upgrades the pango patch to:
https://dwm.suckless.org/patches/pango/dwm-pango-20230520-e81f17d.diff
The changes are fixes for some vertical alignment issues that were obvious only for CJK fonts.
The implementation in dwm-flexipatch is still simplified compared to the original patch, e.g.
avoiding changes like drw->fonts to drw->font and many similar function signatures.
This involves always having configuration for floating border, regardless of
whether it is used or not. Also permanently dropping the const expectation
for color configuration in dwm, so that vtcolors and xrdb patches can change
color configuration.
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).
