Missing info in doc/filters.texi.

@item eval
Specify when to evaluate @var{width} and @var{height} expressions.

It accepts the following values:

@table @samp
@item init
Only evaluate expressions once during the filter initialization or when
a command is processed.

@item frame
Evaluate expressions for each incoming frame.
@end table

Default value is @samp{init}.
