Instead of returning BadAccess when "read" permission is denied
on a device, falsify the device state (buttons down, keys pressed).
This is nicer to applications, but may still have undesired side
effects. The long-term solution is not to use these requests in
event-driven code!
Requests affected: QueryPointer, QueryKeymap, XiQueryDevice.

In server 1.6, all devices are attached to the master device (VCP or VCK).
Sending an event through the master device means the device is sending core
events. If a device is configured as SendCoreEvents, just send through the
device, not through the master.

The smart scheduler is designed to minimize scheduler overhead by
increasing the interval between WaitForSomething calls when a single
client is running. However, the software rotation code depends on
its BlockHandler being invoked for screen updates; the long delays
caused by the smart scheduler optimizations means that screen updates
can be delayed a long time as well.
The change is simple -- prevent the smart scheduler from increasing
the scheduling interval while any screen is using software rotation.

The builtin-fonts configure option was removed, as it at best should
have been a runtime option. Instead, now it always register all "font
path element" backends, and adds built-ins fonts at the end of the
default font path.
This should be a more reasonable solution, to "correct" the most
common Xorg FAQ (could not open default font 'fixed'), and also don't
break by default applications that use only the standard/historical
X Font rendering.

If the MD's lastSlave was a devices with custom axes ranges, then a
WarpPointer would position the cursor at the wrong location. A WarpPointer
request provides screen coordinates and these coordinates were scaled to the
device range before warping.
This patch consists of two parts:
1) in the WarpPointer handling, get the lastSlave and post the event through
this device.
2) assume that WarpPointer coordinates are always in screen coordinates and
scale them to device coordinates in GPE before continuing. Note that this
breaks device-coordinate based XWarpDevicePointer calls (for which the spec
isn't nailed down yet anyway) until a better solution is found.

The old model was implemented based on a misunderstanding of NotifyVirtual and
NotifyNonlinearVirtual events. It became complicated and was broken in some
places [1]. This patch wipes this model completely.
A much simplified implementation is provided instead. Rather than a top-down
approach ("we have a tree of windows, which ones need to get which event")
this one uses a step-by-step approach. For each window W between A and B
determine the pointer window P as perceived by this window and determine the
event type based on this information. This is in-line with the model described
by Owen Taylor [2].

Devices are only activated once - right after they've been added to the
server. If a device failes activation, it's dead. There's no reason to
continue. Return the error code from ActivateDevice() without setting up

Then - in the DDX - just remove the device again.

Server 1.6 uses the X Input 1.x input model, where the core devices (VCP and

instead stay at the default number of classes at all times.

This prevents a protocol visible side-effect (XVisibilityEvent) on
XCompositeRedirectWindow() followed by a XCompositeUnredirectWindow().
The problem shows up in gnome-screensaver with compiz and "unredirect
fullscreen windows" enable. A VisibilityNotify event is generated (first
with obscured and than with unobscured) when the window swithces from
redirected to unredirected.

As proposed by Owen Taylor [1], the enter-leave event model needs to adjust
the events sent to each window depending on the presence of pointers in a
window, or in a subwindow.
The new model can be summarised as:
- if the pointer moves into or out of a window that has a pointer in a child
window, the events are modified to appear as if the pointer was moved out of
or into this child window.
- if the pointer moves into or out of a window that has a pointer in a parent
window, the events are modified to appear as if the pointer was moved out of
or into this parent window.
Note that this model requires CoreEnterLeaveEvent and DeviceEnterLeaveEvent to
be split and treated separately.
