Transport Pixmap from GetNativeSurfaceHandle via css::uno::Any as sal_Int64
The values returned from GetNativeSurfaceHandle are only used in
cairocanvas::CanvasBitmap::getFastPropertyValue
(canvas/source/cairo/cairo_canvasbitmap.cxx), whose consumers in turn are (at
least the ones I could identify):
* OGLTransitionerImpl::setSlides
(slideshow/source/engine/opengl/TransitionerImpl.cxx), passing the
values on to X11SalObject::SetLeaveEnterBackgrounds, which extracts the
Pixmap value to pass it on to XSetWindowBackgroundPixmap.
* X11SalBitmap::Create (vcl/unx/generic/gdi/salbmp.cxx), which extracts the
Pixmap value to pass it on to X11SalBitmap::ImplCreateFromDrawable (as a
Drawable) and to XFreePixmap.
While Pixmap XIDs are apparently 32-bit in the X11 protocol, see e.g.
<https://www.x.org/releases/X11R7.7/doc/xproto/x11protocol.html>, Xlib and the
underlying /usr/include/X11/Xdefs.h appear to be somewhat confused whether the
typedef for XID should be unsigned long (presumably stemming from times when
long was universally 32-bit) or CARD32, see e.g. <https://gitlab.freedesktop.org
/xorg/proto/xorgproto/-/blob/master/include/X11/Xdefs.h>. So conservatively
stick to a 64-bit type here, even if it should only ever contain 32-bit values.
