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

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].

Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.
This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)
LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.
xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).
Rather than assuming rules in the CoreKeyboardProc, init the default rules in
InitCoreDevices, then re-use them later.
In the xfree86 DDX, set the rules to "base" or "evdev", depending on whether
we'll load kbd or evdev.

previously.

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.

The current code exposes to inconsistent updates, i.e. if handler N succeeds
but handler N+1 fails in setting the property, an error is returned to the
client although parts of the server now behave as if the property change
succeeded.
This patch adds a "checkonly" parameter to the SetProperty handler. The
handlers are then called twice, once with checkonly set to TRUE.
On the checkonly run, handlers _MUST_ return error codes if the property
cannot be applied. Handlers are not permitted to actually apply the changes.
On the second run, handlers are permitted to apply property changes.
Errors codes returned on the second run are ignored.
For two axes [a, b] and [x, y] (inclusive), the formula to scale point P(ab)
to (x,y) is:
(P - a)/(b - a) * (y - x) + x
And the whole end result rounded of course to get the integer we need.
It's not especially obvious, and unpleasantly overloaded for the Xnest
case. Typically this gives you a server that looks for its auth data in
the authority file you were using for the running X session, which
generally doesn't have an entry for the display you just started.
All the major dm's, and startx, pass -auth explicitly, so this shouldn't
cause too much upheaval.
A property can only be deleted if any of the following is true:
- if a property is deletable and all handlers return Success.
- if a property is non-deleteable and the all handlers return Success AND the
delete request does not come from a client (i.e. driver or the server).
A client can never delete a non-deletable property.
Now that the code has been fixed so that Unmap means unmap and not "don't
remap", 'remap' was confusing to have in the function names/parameters, so
change it to simple 'map'.

Since ReparentWindow() does a unmap/map pair for windows that are already
mapped, for saveset windows with SaveSetUnmap, we must unmap the window
before calling ReparentWindow() to avoid the generation of MapRequest
events, and so forth.
For master devices, the ptraccel code could segfault on free since we'd be
dereferencing random memory. Callocing the valuatorClassRec is the easy fix.
This removes yet another xalloc() each server generation. Also, I
couldn't find the corresponding xfree() so I guess that used to be a
memory leak there.
Two corrections
1. the "detail" field has NotifyVirtual, etc., not the "mode" field. This was
a clear bug.
2. don't set/unset the flags for NotifyGrab or NotifyUngrab. Clients are
expected to deal with multiple enter/leave events per window if the mode is
not NotifyNormal.
Testable with TCL menu boxes (such as used in gitk):
tk_optionMenu .menu globVar Val1 Val2 Val3 ValJunk
pack .menu
Thanks to Michel Dänzer for pointing this out.
Unplug a mouse, then warp the pointer and the warp pointer code will try
to update the position of the last slave device associated with the
master. That pointer will be stale and the X server will crash.

This was to account for cases where you had video and print screens in
the same server. Lunacy. Leave the slot in ScreenInfo, but rename it,
and stop looking at it.
Add strncasecmp (as we're now using it) in case someone doesn't have it,
and also change strncasecmp args to be const, in accordance with
everything else.
In the map stored in each keyboard device, the first line refers to
minimum keycode, i.e., the 0th line refers to keycode 8. When not
using XKB the wrong test caused some keys to be interpreted as
locks ('m' for instance). The had to be pressed twice to generate
both KeyPress and KeyRelease events.

We may need more than one handler to deal with a property (e.g. one in the
driver, one in the DIX), so get the handlers into a linked list and call them
one-by-one. This is of course slightly less entertaining than the hilarious
WRAP/UNWRAP game we play in other parts of the server.
XIRegisterPropertyHandler/XIUnregisterPropertyHandler are the interface
drivers/the DIX should use to attach themselves to the device.
XIDeleteAllDeviceProperties destroys everything, including the handlers.
