- Fix Bug #10928: Sound merging.
Volume is set to maximum, position calculation
is more robust, merging and effective volume
had been extracted to own functions.
- Fix Bug #8032: Border in Levelpause-screen.
Bug was due to conversion from int to double,
division and multiplication by the same factor,
and subsequent implicit conversion to int.
Made in total a loss of 1 pixel in height and
width.
- Small adjustment in options menu.
