74dbcede25 win32: Experimental implementation of device support
Mostly lifted from the core pointer and keyboard X11 backend support.

The win32 backend registers two devices (a core pointer and a core
keyboard) and assigns them to the event structure when doing the
translation from native events to Clutter events.

Thanks to: Samuel Degrande <Samuel.Degrande@lifl.fr> for testing this
patch.

66740e8000 x11: Fill out the :name property of the InputDevices
For the core pointer and keyboard we assign the names ourselves; for
devices coming from XI we can use the XDeviceInfo.name member.

79ad2b6a72 x11: Store core devices on the X11 Backend singleton
Instead of overloading the device id of 0 and 1 we should treat the core
devices as special, and have a pointer inside the X11 backend singleton
structure, for fast access.

8a579838d5 device: Unset the cursor actor when leaving the stage
When an InputDevice leaves a stage we set the stage member of
InputDevice to NULL. We should also unset the cursor_actor (as the
device is obviously not on an actor any more).

When the device re-enters the Stage the ENTER/LEAVE event generation
machinery will then be able to emit the ENTER event on the Stage.

25c6ebbb2c x11: Discard the LeaveNotify for off-stage ButtonRelease
If the user presses a button on a pointer device and then moves out the
Stage X11 will emit the following events:

  LeaveNotify ➔ MotionNotify ... ➔ ButtonRelease ➔ LeaveNotify

The second LeaveNotify differs from the first by the state field.

Unfortunately, ClutterCrossingEvent doesn't have a modifier_state field
like other events, so we cannot provide a way for programmatically
distinguishing them from a Clutter perspective. This is also an X11-ism
we might not even want to replicate on every backend with sane
enter/leave semantics.

For this reason we should check inside the X11 event processing if the
pointer device has already left the Stage and ignore the second
LeaveNotify.

8736b53d7c device: Do not overwrite the stage for an InputDevice
The Stage field of an InputDevice is set by the backend, whenever the
pointer enters or leaves the Stage. The Stage should not overwrite the
stage field for every event it processes.

cf8a06f018 device: Store the current state, not the previous
The previous state for the device is used by the click count machinery
and we should not be overwriting it at every event; instead, we should
use a parallel storage for the current state coming from the windowing
system.

68b47e3ed4 tests: Fix test-events output
• The enter/leave event line should take into account the case where
  the related field is set to NULL (meaning entering from off-stage
  and leaving the stage).

• The ButtonRelease line shows the click count but uses the button; the
  button *and* the click count should be displayed for both ButtonPress
  and ButtonRelease, to verify they match.

9506510d1c Move all picking-related operations inside InputDevice
The InputDevice objects stores pointer coordinates, state, stage and
the actor under the cursor, so if the current backend provides us with
one attached to the Event structure then we want the InputDevice itself
to update its state and give us the ClutterActor underneath the
pointer's cursor.

1ef40b8823 test-cogl-npot-texture: Use the COGL_TEXTURE_NO_ATLAS flag

08b8b2791f cogl-atlas-texture: Don't create atlas textures with the premult bit
Previously the atlas textures were being created with whatever format
the first sub texture is in. Only three formats are supported so this
only matters if the first texture is a premultiplied alpha
texture. Instead it now masks out the premultiplied bit so that the
textures are always either RGB_888 or RGBA_8888.

14a28620ae win32: Use an invisible cursor when cursor-visible is FALSE
The win32 backend now handles the WM_SETCURSOR message and sets a
fully transparent cursor if the cursor-visible property has been
cleared on the stage. The icon is stored in the library via a resource
file. The instance handle for the DLL is needed to load the resource
so there is now a DllMain function to grab the handle.

ff1d9cf090 test-texture-fbo: Disconnect the paint handler for the stage
Otherwise the paint handler will still be run for the subsequent
tests. This ends up writing to the ‘state’ variable which used to be
on the stack so it will end up corrupting some stack variable. This
was causing test-cogl-premult to fail.

ce030a3fce clutter-group: Use g_list_foreach in clutter_group_real_foreach
g_list_foreach has better protection against the current node being
removed. This will happen for example if someone calls
clutter_container_foreach(container, clutter_actor_destroy). This was
causing valgrind errors for the conformance tests which do just that.

c4adefffd3 cogl-atlas-texture: Fix premultiplied texture formats
When uploading texture data it was just calling cogl_texture_set_data
on the large texture. This would attempt to convert the data to the
format of the large texture. All of the textures with alpha channels
are stored together regardless of whether they are premultiplied so
this was causing premultiplied textures to be unpremultiplied
again. It now just uploads the data ignoring the premult bit of the
format so that it only gets converted once.

b78024bd2d cogl-primitives: Ensure the mipmaps for a layer before logging quads
With the atlas texture backend ensuring the mipmaps can make it become
a completely different texture which will have different texture
coordinates or may even be sliced. Therefore we need to ensure the
mipmaps before deciding which quads to log in the journal. This adds a
new private function to cogl-material which ensures the mipmaps if
needed.

36f18e5ac5 cogl: Make CoglSubTexture only work for quad rendering
The sub texture backend doesn't work well as a completely general
texture backend because for example when rendering with cogl_polygon
it needs to be able to tranform arbitrary texture coordinates without
reference to the other coordintes. This can't be done when the texture
coordinates are a multiple of one because sometimes the coordinate
should represent the left or top edge and sometimes it should
represent the bottom or top edge. For example if the s coordinates are
0 and 1 then 1 represents the right edge but if they are 1 and 2 then
1 represents the left edge.

Instead the sub-textures are now documented not to support coordinates
outside the range [0,1]. The coordinates for the sub-region are now
represented as integers as this helps avoid rounding issues. The
region can no longer be a super-region of the texture as this
simplifies the code quite a lot.

There are two new texture virtual functions:

transform_quad_coords_to_gl - This transforms two pairs of coordinates
     representing a quad. It will return FALSE if the coordinates can
     not be transformed. The sub texture backend uses this to detect
     coordinates that require repeating which causes cogl-primitives
     to use manual repeating.

ensure_non_quad_rendering - This is used in cogl_polygon and
     cogl_vertex_buffer to inform the texture backend that
     transform_quad_to_gl is going to be used. The atlas backend
     migrates the texture out of the atlas when it hits this.
