dependency instance
Dep is very much like a
Val, but is also aChannel. The basic purpose is to represent a value dependent upon another variable. An example of this might be if you are representing a positionleftand you also wanted to representrightas well (which would beleft+width). These two variables are dependent upon each other and don't fit well asVars. An example usage might be:val left: Var[Double] = Var(0.0) val width: Var[Double] = Var(0.0) val right: Dep[Double, Double] = Dep(left, width)If an instance is
submissiveit removesadjustmentfrom being part of the mutation dependency. For example: in the above scenario if you setwidthto 100.0 andrightto 125.0 thenleftwill be 25.0. Now, what should happen if you changewidthto 50.0? Shouldleftchange to 75.0 (submissive = false) or shouldrightchange to 75.0 (submissive = true)?
