is there an opcode that does the same as
csoundRewindScore() in the API?

if not, it would be cool to have one!

i am imagining users having a GUI widget slider that allows them
to "scrub" the score.

negative numbers seeking to score position seems unintuitive to me.
so how about this,  2 opcodes:

scoreoffset ival
scoreseek kval

where 'scoreoffset' is an i-time opcode, equivalent to
	csoundSetScoreOffsetSeconds(ival)

and 'scoreseek' is a p-time opcode, equivalent to
	csoundSetScoreOffsetSeconds(kval)
	csoundRewindScore()

thanks,
m
