make sure that for a given event (widget/object/module, whatever), only
a *single* input event per button can be registered at one time.
the problem otherwise is with modules that re-register their widgets
with the same IDs (cmus, spotify, etc.): Each time the widget is
re-created (each intervall, typically), it re-registers an input event,
creating an always longer list of callbacks being executed when the
button is clicked (not speaking of the memory leak this introduces).
fixes#668
make it possible to toggle the display state of a widget between
"displayed" and "minimized" also for modules that re-create their
widgets during each iteration.
see #661
by default, allow toggling the minimized state of a widget via the
middle mouse and draw a single unicode char instead of the actual
widget, maintaining all states.
fixes#661
Previous code accepted the "first" hit in a theme - particularly, if a
module is called "A" and a *different* module "B" uses "A" as state, a
widget of module B with state A would be themed as *module* A, wrongly.
Essentially, made sure that the last (most specific) themeing "wins".
fixes#647
when scrolling text that is subject to *slight* changes (e.g. a song
that contains the current position within the song), allow for slight
variations in the displayed text.
fixes#629
OK - so I have to admit I *hate* the fact that PIP seems to require a
subdirectory named like the library.
But since the PIP package is something really nifty to have (thanks to
@tony again!!!), I updated the codebase to hopefully conform with what
PIP expects. Testruns so far look promising...
to make errors easier to diagnose, do not scroll them, but instead fully
show them.
also, re-introduce the supplementary fields for the dwm bridge, kudos to
@somospocos
