Since grabs are now expected to be allocated/freed with AllocGrab and

masks. Until the callers are switched to use FreeGrab, this introduces

The record extension needs the major and minor opcodes in the reply
hook, but the request buffer may have been freed by the time the hook
is invoked. Saving the request major and minor codes as the request is
executed avoids fetching from the defunct request buffer.
This patch also eliminates the public MinorOpcodeOfRequest function,
inlining it into Dispatch. Usages of that function have been replaced
with direct access to the new ClientRec field.

There are plenty of cases that can only be triggered by a real bug in the
server and doing the ErrorF dance manually everywhere is a tad painful and
the error message is usually used only to find the spot in the file anyway.
Plus, reading BUG_WARN somewhere is a good indicator to the casual reader
that this isn't intended behaviour.
Note that this is intentionally different to the BUG_ON behaviour on the
kernel, we do not FatalError the server. It's just a warning + stacktrace.
If the bug is really fatal, call FatalError.

miPointerSetPosition traditionally took coordinates on a per-screen basis,
triggering a screen switch when these went out-of-bounds. For absolute
devices, this prevented screen crossing in the negative x/y direction.
This patch changes the event generation patch to handle screen coordinates
in a desktop range (i.e. all screens together). Screen switches are
triggered when these coordinates are not on the current screen.
This unifies the pointer behaviour of single ScreenRec multihead and
multiple ScreenRecs multihead in that the cursor by default moves about the
whole screen rather than be confined to one single screen. The
transformation matrix may then be used to actually confine the cursor to the
screen again.
Note: fill_pointer_events has to deal with several different coordinate
systems. Make sure you read the comment before trying to understand the code.

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.
