- "Is this strip type an effect?" has been done by reserving 3rd bit
of the effect enum values to indicate that. That is a very strange
decision, so make that be done by strip_is_effect() function. The
enum values have to stay the same for backwards compat however.
- Both "strip type" and "strip blend mode" were sourced from the
same STRIP_TYPE_ enum, with only parts of the values meant for "type",
and other parts of values meant for "blend mode". That again is highly
confusing; split that off into two enums. Yes there's a handful of
values in them that overlap, but not the majority.
