shell, st: Adjust to CoglPipeline API changes
cogl_pipeline_set_layer_null_texture() now doesn't receive
the texture type, since it only supports 2D textures now.

37f53a42da st: Create shadow pipeline taking resource scale in account
The shadow pipeline is created doing software blurring of the texture so the
shadow spec blur parameter should be scaled accordingly with the texture scaling
otherwise we won't take enough pixels in account creating stronger shadows.

5617ffc79c st: Use scaled surfaces for creating cairo background shadows
Create the surfaces for background shadows at scaled sizes and then draw on them
using logical coordinates, by setting the surface device scale accordingly.

Use the said surface scale when generating the actual shadow cairo pattern
but in such case, to reduce the number of code changes, is better to work in
absolute coordinates, and to do so:
  1) Create a temporary shadow-spec copy with scaled values to absolute sizes
  2) Invert the scaling on the shadow matrix
  3) Do the actual painting in absolute coordinates
  4) Set the shadow matrix scaling back to the logical coordinates.

Finally scale down the created shadow pattern surface size when painting it,
applying again a reverse scale to the matrix.

5d4a804c90 st-shadow: Ceil size before comparing with texture
A fractional resource scale would mean we never use the fast path for
creating the shadow, because we'd cast the int to a float before
comparing, which would never match.

Instead compare the expected texture size with the source texture, to
actually potentially trigger the fast path.

st: Check for ClutterImage when creating shadow pipelines
_st_create_shadow_pipeline_from_actor creates shadow pipelines
from actors. This function special-cases ClutterTexture as a
small performance improvement, since we can have access to the
CoglTexture easily with it. However, recent commits removed all
usage of ClutterTexture from GNOME Shell, rendering this optimization
useless. Instead, actors now may have a ClutterImage set as
their content, that can be used instead.

Replace the check for ClutterTexture with a check for ClutterImage,
and use the texture of the image when it is available.

st-private: Receive a CoglFramebuffer
Same case of the previous patch; _st_paint_shadow_with_opacity()
uses cogl_get_draw_framebuffer(), and this patch makes it receive
a CoglFramebuffer as a parameter instead.

The cautious reader might notice that this commit apparently goes
against the long-term goal, for it introduces more instances of
cogl_get_draw_framebuffer(). This is not wrong, but these introduced
ones will be removed later on, when ClutterActor.paint() receives
a CoglFramebuffer as a parameter instead.

st: Remove deprecated cogl_texture_new()
cogl_texture_new() is used in a few places in GNOME Shell, but
it's a deprecated Cogl function. The replacement is the less
verbose cogl_texture_2d_new_with_size(), that is very much a
straightforward replacement.

Remove the few places where this function is used, replacing
it by the CoglTexture2d counterpart.

f6a08472a0 st: Do not force allocation updates during shadow creation
If an actor is pending a relayout when get_allocation_box() is called,
the method forces an allocation update. In case of StWidget, this might
then result in a style update and a consecutive invalidation of the
shadow spec.

A helper method that invalidates one of its parameters as a side effect
(and by extension its return value as well) is most unexpected, so cur-
rently _st_create_shadow_pipeline_from_actor() poses an easy trap to
callers to run into.

Remove that trap by calling get_size()/get_position() instead, which
don't have the unintended side effect - it is still a good idea to fix
callers who were running into this to not waste resources on creating
shadows that are invalidated before the next paint, but throwing un-
defined behavior at them is harsh ...

7015bb2ca9 shadow: Only use correctly sized textures for shortcut
When creating a shadow for a ClutterTexture, we currently use the
underlying CoglTexture directly instead of rendering the actor to
an offscreen buffer. This assumes that the CoglTexture is directly
suitable as shadow source, which isn't necessarily the case - it
may have a very different size than what is shown and scaled up or
down by the hardware. In that case we end up with a scaled shadow
texture as well, which messes up the desired blur effect - the
result will be too light when scaling up, or too sharp when scaling
down. To fix this, only take the shortcut when a ClutterTexture's
underlying texture has the correct size and fall back to offscreen
rendering otherwise.

63f6ff9151 Do not skip CoglError parameters
While CoglError is a define to GError, it doesn't follow the convention
of ignoring errors when NULL is passed, but rather treats the error as
fatal :-(
That's clearly unwanted for a compositor, so make sure to always pass
an error parameter where a runtime error is possible

6d22670307 Defend against failure of cairo_pattern_get_surface()
There are quite a few crashes in retrace.fedoraproject.org that are a result of
of cairo_pattern_get_surface() failing, then a subsequent call to
cairo_image_surface_get_width() crashing because no surface was returned to the
out parameter. Knowing what causes these is hard - my best guess is widgets getting
allocated at ridiculous sizes - but avoiding the crash makes sense in any case.

d6fe008b2c st-shadow: Fix offset shadow offscreen rendering
The shadows are currently rendered by painting the actor we want to
apply shadow on, in an offscreen buffer. The problem is that when this
actor has an allocation padding (ie allocation that isn't at 0x0
relatively to its parent), this padding is added within the offscreen
buffer and as a result the shadow rendering is truncated because the
offscreen buffer size is the size of the allocation box, not the
allocation box + padding.

This patch reposition the actor at 0x0 with rendering it by changing
the initial transformation matrix when rendering the actor offscreen.

d66e7dd49e st-theme-node-drawing: Don't create lots of one-shot materials
A few places in st-theme-node-drawing create one-shot material, paint
with it and then free it. This is suboptimal with current Cogl because
it will end up compiling an ARBfp program just for that single paint
and then it will throw it away when the material is destroyed.

There is a new function in st-private.c called
_st_create_texture_material. This creates a simple material for a
texture based on a common parent material that points to a dummy
texture. Any materials created with this function are likely to be
able to share the same program unless the material is further modified
to contain a different number of layers. It would be possible to use
cogl_set_source_texture for this instead except that it's not possible
to modify the material's color in that case so we couldn't render the
texture with opacity.

The corner textures are now stored as a handle to a material that
references the texture rather than storing the texure directly. There
is also a separate border_material member which always points to
border_texture as the only layer.
