e721fde259 backends: Add argument for best scale on MetaCursorSprite::prepare-at
Instead of letting implementations poke backend internals from various
places, give that information right away.

1fc7935858 backends/cursor: Add API to set and get the texture buffer transform
In Wayland clients can commit transformed surfaces, so the compositor
can directly use them on hardware planes. We already support that
for other surfaces, this is the first step to also support it on
cursor sprites.

2f4a68c8c3 Clean up include macros mess
The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.

817c8e568c wayland: Add wl_surface backed cursor sprite implementation
This removes the last use of the non-abstract form of MetaCursorSprite
usage.

3c538d4a92 backends/cursor: Move out Xcursor functionality into own type
Introduce a new type MetaCursorSpriteXcursor that is a MetaCursorSprite
implementation backed by Xcursor images. A plain MetaCursorSprite can
still be created "bare bone", but must be manually provided with a
texture. These usages will eventually be wrapped into new
MetaCursorSprite types while turning MetaCursorSprite into an abstract
type.

2fc978ca9d backends/cursor: Rename X11 cursor creation function
It was prefixed with meta_cursor_, but it took a X11 Display, so update
the naming. Eventually it should be duplicated depending if it's a
frontend X11 connection call or a backend X11 connection call and moved
to the corresponding layers, but let's just do this minor cleanup for
now.

2a20df0c50 backends/cursor: Make MetaCursorSprite derivable
This makes it possible to move out backing store specific code (such as
Xcursor handling) to separate units, while also making it easier to add
more types).

79c86ae890 Support scaling of cursor sprites given what output they are on
This commits refactors cursor handling code and plugs in logic so that
cursor sprites changes appearance as it moves across the screen.
Renderers are adapted to handle the necessary functionality.

The logic for changing the cursor sprite appearance is done outside of
MetaCursorSprite, and actually where depends on what type of cursor it
is. In mutter we now have two types of cursors that may have their
appearance changed:

 - Themed cursors (aka root cursors)
 - wl_surface cursors

Themed cursors are created by MetaScreen and when created, when
applicable(*), it will extend the cursor via connecting to a signal
which is emitted everytime the cursor is moved. The signal handler will
calculate the expected scale given the monitor it is on and reload the
theme in a correct size when needed.

wl_surface cursors are created when a wl_surface is assigned the
"cursor" role, i.e. when a client calls wl_pointer.set_cursor. A
cursor role object is created which is connected to the cursor object
by the position signal, and will set a correct texture scale given what
monitor the cursor is on and what scale the wl_surface's active buffer
is in. It will also push new buffers to the same to the cursor object
when new ones are committed to the surface.

This commit also makes texture loading lazy, since the renderer doesn't
calculate a rectangle when the cursor position changes.

The native backend is refactored to be triple-buffered; see the comment
in meta-cursor-renderer-native.c for further explanations.

d3fdaa3232 MetaCursorSprite: Put renderer specific code in the renderer
There were lots of code handling the native renderer specific cases;
move these parts to the renderer. Note that this causes the X11 case to
always generate the texture which is a waste of memory, but his
regression will be fixed in a following commit.

The lazy loading of the texture was removed because it was eventually
always loaded anyway indirectly by the renderer to calculate the
current rect.

165050f8f9 backends: Get rid of meta-cursor-private.h
There is nothing special about the private API which only consists of
getters for renderer specific backing buffer. Lets them to the regular
.h file and treat them as part of the normal API.

a proper backend system.
