/* This is a special type of DrawTarget. It duplicates all drawing calls

|
|
* dual DrawTarget is used as the source for any surface data. In this case
|
|
* the snapshot of the first source DrawTarget is used as a source for the call
|
|
* to the first destination DrawTarget (mA) and the snapshot of the second
|
|
* source DrawTarget is used at the source for the second destination
|
|
* DrawTarget (mB). This class facilitates black-background/white-background
|
|
* drawing for per-component alpha extraction for backends which do not support
|
|
* native component alpha.
