Commit 587c3a2d19 fixed DoGetImage to
check windows against their backing drawables, rather than against the
screen dimensions, to prevent reading outside the bounds of redirected
windows' backing pixmaps (see bug #22804). Unfortunately, while
making that change I also removed the check that the rectangle is
contained within the bounds of the source window, which is a violation
of the specification:
If the drawable is a window, the window must be viewable, and it
must be the case that, if there were no inferiors or overlapping
windows, the specified rectangle of the window would be fully
visible on the screen *and wholly contained within the outside
edges of the window* (or a Match error results). Note that the
borders of the window can be included and read with this request.
(emphasis mine)
Reinstate the window dimension check, to return BadMatch if the
GetImage request falls outside the bounds of the window.

When closing down all devices, we manually unset master for all attached
devices, but the device's sprite info still points to the master's sprite
info. This leaves us a window where the master is freed already but the
device isn't yet. A signal during that window causes dereference of the
already freed spriteInfo in mieqEnqueue's EnqueueScreen macro.
Simply block signals when removing all devices. It's not like we're really
worrying about high-responsive input at this stage.

The protocol requires that the emulated event is marked as such. So if a
driver with smooth scrolling axis sends legacy button events, the motion
event must be marked as emulated.
Pass the real type to emulate_scroll_button_events and create the events
accordingly. For real button press or relase events, only that event must be
generated since a release event will follow or a press event has already
occured, respectively. (This fixes a bug where we'd get two release events
for each legacy button event)

Don't switch between doubles and ints in the caller, instead take doubles in
miPointerSetPosition and do the conversion there. For full feature we should
change everything down from here for doubles too.
Functional change: previously we'd restore the remainder regardless of
screen switching/confinement (despite what the comment said). Now,
screen changing or cursor constraints will cause the remainder be clipped
off. This should happen for cursor constraints but arguably not for screen
crossing.
This also corrects a currently wrong comment about miPointerSetPosition's
input coordinates.

For scroll wheel support, we used to send buttons 4/5 and 6/7 for
horizontal/vertical positive/negative scroll events. For touchpads, we
really want more fine-grained scroll values. GetPointerEvents now
accepts both old-school scroll button presses, and new-style scroll axis
events, while emitting both types of events to support both old and new
clients.
This works with the new XIScrollClass to mark axes as scrolling axes.
Drivers mark any valuators that send scroll events with SetScrollValuator.
(Currently missing: the XIDeviceChangeEvent being sent when a driver changes
a scroll axis at run-time. This can be added later.)
Note: the SCROLL_TYPE enums are intentionally different values to the XI2
proto values to avoid copy/overlapping range bugs.
