/**
|
|
Represents a linear source of mouse events from a mouse device or individual finger
|
|
in a multi-touch environment.
|
|
|
|
Each MouseEvent object contains a reference to the MouseInputSource that generated
|
|
it. In an environment with a single mouse for input, all events will come from the
|
|
same source, but in a multi-touch system, there may be multiple MouseInputSource
|
|
obects active, each representing a stream of events coming from a particular finger.
|
|
|
|
Events coming from a single MouseInputSource are always sent in a fixed and predictable
|
|
order: a mouseMove will never be called without a mouseEnter having been sent beforehand,
|
|
the only events that can happen between a mouseDown and its corresponding mouseUp are
|
|
mouseDrags, etc.
|
|
When there are multiple touches arriving from multiple MouseInputSources, their
|
|
event streams may arrive in an interleaved order, so you should use the getIndex()
|
|
method to find out which finger each event came from.
