Improvement: --glx-swap-method & --fade-exclude
- GLX backend: Add --glx-swap-method, to reduce painting region if the driver uses exchange or copy buffer swaps. Untested. - Add --fade-exclude, to disable fading on specific windows based on some conditions. Untested. - Expose GLX backend options through configuration file. Add fetching of GLX backend options through D-Bus. - Use NULL pointer instead of element count to delimit string arrays in parse_vsync()/parse_backend()/parse_glx_swap_method(). - Add documentation about "wintypes" section in configuration file.

CONFIGURATION FILES
|
||||
-------------------
|
||||
compton could read from a configuration file if libconfig support is compiled in. If *--config* is not used, compton will seek for a configuration file in `$XDG_CONFIG_HOME/compton.conf` (`~/.config/compton.conf`, usually), then `~/.compton.conf`, then `compton.conf` under `$XDG_DATA_DIRS` (often `/etc/xdg/compton.conf`). Most commandline switches could be replaced with an option in configuration file, and some options are exposed only in configuration files (presently, some window-type-specific settings). compton uses general libconfig configurtion file format. A sample configuration file is available as `compton.sample.conf` in the source tree.

|

compton uses general libconfig configurtion file format. A sample configuration file is available as `compton.sample.conf` in the source tree. Most commandline switches each could be replaced with an option in configuration file, thus documented above. Window-type-specific settings are exposed only in configuration file and has the following format:
|

|
||||
------------
|
||||
wintypes:
|
||||
{
|
||||
WINDOW_TYPE = { fade = BOOL; shadow = BOOL; opacity = FLOAT; focus = BOOL; };
|
||||
};
|
||||
------------
|
||||
|
||||
'WINDOW_TYPE' is one of the 15 window types defined in EWMH standard: "unknown", "desktop", "dock", "toolbar", "menu", "utility", "splash", "dialog", "normal", "dropdown_menu", "popup_menu", "tooltip", "notify", "combo", and "dnd". "fade" and "shadow" controls window-type-specific shadow and fade settings. "opacity" controls default opacity of the window type. "focus" controls whether the window of this type is to be always considered focused. (By default, all window types except "normal" and "dialog" has this on.)
