Xwayland will eventually need the current client in dri3_open. Simply
changing that API is not an option though as other drivers that
implement DRI3 will not have a matching function signature and will
crash when called.
Add a new dri3_open_client function pointer and bump
DRI3_SCREEN_INFO_VERSION so that drivers can be aware of the new
function which will be used in preference to the old function when
available.

load_cursor_argb() may need to be able to fail and have the server fall back
to a software cursor in at least the following circumstances.
1) The hardware can only support some ARGB cursors and this does not just
depend on cursor size.
2) Virtual hardware may not wish to pass through a cursor to the host at a
particular time but may wish to accept the same cursor at another time.
This patch adds a return value to the API and makes the server do the
software fall-back on failure.

Started out as an Xorg module to be used from Xorg drivers to let
Xorg run under a wayland server. The idea was to be able to reuse the
2D acceleration from the Xorg driver. Now with glamor being credible,
a better plan is to just make Xwayland its own DDX, similar to Xwin
and Xquartz. This is a much better fit, as much of the code in the
original approach had to hack around Xorg doing Xorg things like take
over the VT, probe input devices and read config files. Another big win
is that Xwayland dosn't need to be setuid root.
The Xwayland support for DRI3, Glamor and render nodes was done by
Axel Davy <axel.davy@ens.fr>, who also did a lot of work on the rebase
to the Xwayland DDX.

I think the sense of the return value was just flipped here; if you
return TRUE, then the calling code assumes that the pixmap *has* been
uploaded and that an FBO is available. When it tries to use it, it

This was the wrong fix to the problem, and it triggered a change in XKB
behavior: previously a button event would unlock a latched modifier, now it
doesn't anymore.
https://bugs.freedesktop.org/show_bug.cgi?id=73155
Note that the new behavior is is strictly spec compliant but we've had the
other behavior for a long time so we shouldn't break it.
The bug this patch originally fixed was a null-pointer dereference when
releasing button events on server shutdown. This was addressed by the commit
below, so the need for this patch has gone away anyway.

Normally composite will decide to add implicit redirection when a
window with an alternate visual is a parent of a window with a regular
visual or vice versa. This uses extra pixmap memory and incurs an extra
copy. This exception mechanism provides a way for a DDX to override this
if the DDX knows that its acceleration architecture will render correctly.
The relevant case is that of an RGB window reparented into a ARGB parent
frame window. If the DDX knows that the acceleration architecture in use
will pad the alpha channel to opaque when rendering to the RGB window,
the implicit redirection can be avoided.
This patch adds a new composite function:
CompositeRegisterImplicitRedirectionException()
which lets a DDX register a pair of parent and child window visuals, that
will not be implicitly redirected even if the normal policy would have
made that choice.

The width parameter is used to disable the blit fast-path (memcpy) when
source and destination rows overlap in memory. This check was added in [0].
Unfortunately, the calculation to determine if source and destination
lines overlapped was incorrect:
(1) it converts width from pixels to bytes, but width is actually in
bits, not pixels.
(2) it adds this byte offset to dst/srcLine, which implicitly converts
the offset from bytes to sizeof(FbBits).
Fix both of these by converting addresses to byte pointers and width
to bytes and doing comparisons on the resulting byte address.
For example:
A 32-bpp 1366 pixel-wide row will have
width = 1366 * 32 = 43712 bits
bpp = 32
(bpp >> 3) = 4
width * (bpp >> 3) = 174848 FbBits
(FbBits *)width => 699392 bytes
So, "careful" was true if the destination line was within 699392 bytes,
instead of just within its 1366 * 4 = 5464 byte row.
This bug causes us to take the slow path for large non-overlapping rows
that are "close" in memory. As a data point, XGetImage(1366x768) on my
ARM chromebook was taking ~140 ms, but with this fixed, it now takes
about 60 ms.

fb: Fix memcpy abuse
The memcpy fast path implicitly assumes that the copy walks
left-to-right. That's not something memcpy guarantees, and newer glibc
on some processors will indeed break that assumption. Since we walk a
line at a time, check the source and destination against the width of
the blit to determine whether we can be sloppy enough to allow memcpy.
(Having done this, we can remove the check for !reverse as well.)
v3: Convert to byte units
This first checks to make sure the blt is byte aligned, converts all
of the data to byte units and then compares for byte address range
overlap between source and dest.

Glamor has a mode where pixmaps will be constructed from numerous
small FBOs. This allows testing of the tiled pixmap code without
needing to create huge pixmaps.
However, the render glyph code assumed that it could create a pixmap
large enough for the glyph atlas. Instead of attempting to fix that
(which would be disruptive and not helpful), I've added a new pixmap
creation usage, GLAMOR_CREATE_NO_LARGE which forces allocation of a
single large FBO.
Now that we have pixmaps with varying FBO sizes, I then went around
and fixed the few places using the global FBO max size and replaced
that with the per-pixmap FBO tiling sizes, which were already present
in each large pixmap.
Xephyr has been changed to pass GLAMOR_CREATE_NO_LARGE when it creates
the screen pixmap as it doesn't want to deal with tiling either.
