*
* * don't abort if snd_mixer_* functions failed due to EINTR,
* we simply retry on the next cycle. hopefully asoundlib preserves
* errno states correctly (Jaroslav can you asure that?).
*
* * feature WINCH correctly, so we make a complete relayout on
* screen resizes. don't abort on too-small screen sizes anymore,
* but simply beep.
*
* * redid the layout algorithm to fix some bugs and to preserve
* space for a flag indication line. the channels are
* nicer spread horizontally now (i.e. we also pad on the left and
* right screen bounds now).
*
* * various other minor fixes.
*
* * indicate whether ExactMode is active or not.
*
* * fixed coding style to follow the GNU coding conventions.
*
* * reverted record volume changes since they broke ExactMode display.
*
* * composed ChangeLog entries.
