I see there’re 4 types:
greyed, reference, switch and time loops
can anyone tell me their differences?
synfig.com/wiki/Convert#Canvas
All the parameters can be converted to other types:
Greyed: not editable
Reference: It is just a pointer to other canvas parameter not so useful
Switch: Allows to change between one canvas and other quickly
Time Loop: See the Time Loop convert in the link
