Daniel Stenberg d2b625f818 Craig Sather's patch #749974: 
Adds the ability to define 2 or more alternating lines on each line of the WPS
and the ability to control how long each alternating line is displayed before
switching to the next one.

Backward compatible with the current WPS specification language (existing WPS
files will display the same as they do now).
