Apparently SavedCursor is sometime tried to be set while already being set.

xf86_reload_cursors restores the cursor to the correct position, but
that must adjust for cursor hot spot and frame before calling down to
the hardware function, otherwise the cursor jumps to the wrong
position until it is repositioned by the user.

xextproto had Xlib client headers moved into libXext.
Protocol header files are named fooproto.h, header files with constants
foo.h or fooconst.h where foo.h was already in use for client-side headers.

  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).

Also, no need to call ShowCursor when SetCursorPosition already does it

pixman 0.13.2 now holds all of the matrix operations. This leaves
the protocol conversion routines and some ABI stubs in place

Doing projective transforms required repositioning the cursor using the
hotspot, but that requires relocating the upper left corner in terms of said
hotspot.

RandR matrix computations lose too much precision in fixed point;
computations using the inverted matrix can be as much as 10 pixels off.
Convert them to double precision values and pass those around. These API
changes are fairly heavyweight; the official Render interface remains fixed
point, so the fixed point matrix comes along for the ride everywhere.

Replaces the use of the screen pointer itself as the key, which was
nice but won't work now that an array index is being stored.

This fixes a bug on server recycle with ati zaphod.

This patch (and not setting HARDWARE_CURSOR_BIT_ORDER_MSBFIRST on big endian
platforms) fixes it for me with the radeon driver and doesn't break intel.

Correct patch this time :)

This reverts commit 26735257.

Pushed the wrong patch.

See bug 11796

This change uses XORG_VERSION_CURRENT < 7.0 to mean "server newer than 1.2"
since XORG_VERSION current went backwards at some point.

Also add missing exports to hw/xfree86/loader/xf86sym.c

The multi-crtc cursor code in hw/xfree86/modes holds a reference to the
current cursor. This reference must be correctly ref counted so the cursor
is not freed out from underneath this code.

This reverts commit 0f057ebb.

This screws my cursor up just starting a bare X server on Intel,
I get the X more like <> than ><..

Doesn't seem necessary to do anything here...

Replace the ad-hoc transformation mechanisms with matrices.
Prepares for more general transformation as well.

xf86_reload_cursors is supposed to be called from the crtc mode setting
commit hook; as that happens during server initialization, check for this
case.
(cherry picked from commit 5b77bf2d)

This moves most of the cursor management code out of the intel driver and
into the general server code. Of course, the hope is that this code will be
useful for other driver writers as well.

Check out xf86Crtc.h for the usage information, making sure you add the
needed hooks to the crtc funcs structure for your driver.
