[pygame] Events and modifiers (Re: collidepoint)

[Greg Ewing <greg.ewing@xxxxxxxxxxxxxxxx>]

Something that's rather annoying about pygame's event
handling is that the state of the modifier keys is
only reported in key events, not mouse events. This
makes it more awkward than necessary to tell when
e.g. the user has shift-clicked.

It would be more convenient and less error-prone if
all event types included the state of the modifiers
at the time the event occurred -- as most other GUI
systems do.
