Bug Description:
A swing application that registers to handle mouse events
receives an inconsistent sequence when it is minimised
and then redisplayed.
Consistency in mouse events is that a mouse press can be
followed by mouse drag events and IS followed by a mouse
release. Mouse move events occur only outside
press-drag-release sequences. Mouse drag and release occur
only within such a sequence.

Steps to Reproduce (be specific):

Consider the attached program. Compile, and run it.
Then place the pointer over its window, press the left
mouse button and drag the mouse out of its window.
Then, without releasing the button, hit any key.
This has the effect of forcing the minimization of the
window. Then releas the left mouse button, display the
window (with ALT-TAB), and move the mouse over it.
You will see a mouse press event that is follwed by
a mouse move and NOT by a mouse release.
This is disruptive for applications that perform
operations based on mouse gestures.
Such applications could overcome the problem by catching
window events (posing then a constraint on the implementation
of the enclosing window).
The correct behaviour is to generate automatically a
mouse release event.
