there are two x extensions for working with monitors (especially
multiple): xinerama and randr. xinerama is old, feature-poor and in
general isn't used anymore compared to the randr: new, feature-rich and
widely-used. for some reason we were using both of them, so let's drop
xinerama to keep things simple, clean and small. and to be modern.
the drop was done in three steps:
* first step was to replace all the xinerama-based code with the
randr-based one and to replace or remove all the xinerama mentions;
* second step was to replace the xinerama's terminology with the
randr's one. xinerama was referring only to the word "screen", while
randr refers to multiple words and i think the word "monitor" is the
most suitable for us and, hopefully, clear both to a contributor and
to an end user;
* third step was to refactor the new randr-based code if needed and to
address related todo's (mostly about moving related functions
elsewhere).
all the steps were done well except addressing a leftover todo about
moving the win_update_monitor function to the x.c which wasn't done.
the xinerama-shadow-crop option was renamed to crop-shadow-to-monitor,
but it's previous name is still accepted, has effect and the
deprecation message is printed to preserve backwards-compatibility.
Transparent clipping interacts poorly with programs whose transparent
interface elements must show windows below them for functionality,
for example screenshot utilities.
Added the new `clip-shadow-above` configuration and wintype option.
These allow the user to select windows to clip from the shadow region of
other windows, i.e. don't paint shadows on top of them.
This should provide a more useful and userfriendly alternative to the
deprecated `shadow-exclude-reg` option — especially for docks and bars.
This replaces single quotes for double quotes in the configuration
comments that refer to strings.
This was misleading since someone could took that comment as a valid
config entry, which is not. One notable example was `backend = 'glx'`
which is not accepted by libconfig.
This also adds `;` for each default config values for consistency.
**Work-in-Progress**
Add `dual_kawase` to configuration and argument parsing. Allow `kawase`
for backward compatibility. Add `--blur-strength` parameter for
blur-method `dual_kawase`.
Update documentation to reflect the new blur-method and parameters.
leftovers:
1) config file path. Has to implement compatibility functionalities before
we can change it.
2) links in man pages. Has to migrate the repo first.
3) _COMPTON_SHADOW, it has become a defacto standard, so we have to keep
supporting it.
4) dbus names, undecided whether we should/could change it.
