When clutter_score_append_at_marker is called instead of
clutter_score_append the complete_id field of ClutterScoreEntry was
being left uninitialised. When the entry is eventually freed it would
sometimes try to disconnect an invalid signal id. This was causing
conformance test failures for me on GLES2.
We were trying to declare and initializing an arbfp program cache for
GLES but since the prototypes for the _hash and _equal functions were
only available for GL this broke the GLES builds. By #ifdefing the code
to conditionally declare/initialize for GL only this should hopefully
fix GLES builds.

The constant 'True' is defined by Xlib which isn't used for all clutter
builds so this replaces occurrences of True with TRUE which is defined
by glib. This should hopefully fix the win32 builds.

This adds a cache (A GHashTable) of ARBfp programs and before ever
starting to code-generate a new program we will always first try and
find an existing program in the cache. This uses _cogl_pipeline_hash and
_cogl_pipeline_equal to hash and compare the keys for the cache.
There is a new COGL_DEBUG=disable-program-caches option that can disable
the cache for debugging purposes.

This allows us to get a hash for a set of state groups for a given
pipeline. This can be used for example to get a hash of the fragment
processing state of a pipeline so we can implement a cache for compiled
arbfp/glsl programs.

_cogl_pipeline_equal now accepts a mask of pipeline differences and layer
differences to constrain what state will be compared. In addition a set
of flags are passed that can tweak the comparison semantics for some
state groups. For example when comparing layer textures we sometimes
only need to compare the texture target and can ignore the data itself.
In updating the code this patch also changes it so all required pipeline
authorities are resolved in one step up-front instead of resolving the
authority for each state group in turn and repeatedly having to traverse
the pipeline's ancestry. This adds two new functions
_cogl_pipeline_resolve_authorities and
_cogl_pipeline_layer_resolve_authorities to handle resolving a set of
authorities.

This removes the unused array of per-packend priv data pointers
associated with every CoglPipelineLayer. This reduces the size of all
layer allocations and avoids having to zero an array for each
_cogl_pipeline_layer_copy.
If not configured with --enable-cogl2-reference then don't try and dist
the doc/references/cogl-2.0 manual. Although this means a tarball built
this way will not be able to build the experimental cogl-2.0 manual this
isn't considered a big problem since anyone interested in this would
hopefully be tracking git for now or we can simply be careful to
configure with --enable-cogl2-reference for our tarball releases.

A non-static function named cogl_object_get_type was inadvertently added
during the addition of the CoglObject base type, but there is no public
prototype in the headers and it's only referenced inside cogl-object.c
to implement cogl_handle_get_type() for compatibility. This removes the
function since we don't want to commit to CoglObject always simply being
a boxed type. In the future we may want to register hierarchical
GTypeInstance based types.

When a tiled window is maximized (e.g. by clicking the title bar
button), unmaximizing the window restores the tiled state. While
this is reasonable for side-by-side tiling, it is confusing for
"maximize" tiled windows, as unmaximization has no visible effect.
Change unmaximize to only restore the tiled state of side-by-side
tiled windows.
In _cogl_pipeline_needs_blending_enabled after first checking whether
the property most recently changed requires blending we would then
resort to checking all other properties too in case some other state
also requires blending. We now avoid checking all other properties in
the case that blending was previously disabled and checking the property
recently changed doesn't require blending.
Note: the plan is to improve this further by explicitly keeping track
of the properties that currently cause blending to be enabled so that we
never have to resort to checking all other properties we can constrain
the checks to those masked properties.

This moves _cogl_pipeline_get_parent and _cogl_pipeline_get_authority
into cogl-pipeline-private.h so they can be inlined since they have been
seen to get quite high in profiles. Given that they both contain such
small amounts of code the function call overhead is significant.

This adds a debug option called disable-software-clipping which causes
the journal to always log the clip stack state rather than trying to
manually clip rectangles.

Before flushing the journal there is now a separate iteration that
will try to determine if the matrix of the clip stack and the matrix
of the rectangle in each entry are on the same plane. If they are it
can completely avoid the clip stack and instead manually modify the
vertex and texture coordinates to implement the clip. The has the
advantage that it won't break up batching if a single clipped
rectangle is used in a scene.
The software clip is only used if there is no user program and no
texture matrices. There is a threshold to the size of the batch where
it is assumed that it is worth the cost to break up a batch and
program the GPU to do the clipping. Currently this is set to 8
although this figure is plucked out of thin air.
To check whether the two matrices are on the same plane it tries to
determine if one of the matrices is just a simple translation of the
other. In the process of this it also works out what the translation
would be. These values can be used to translate the clip rectangle
into the coordinate space of the rectangle to be logged. Then we can
do the clip directly in the rectangle's coordinate space.

Previously in cogl-clip-state.c when it detected that the current
modelview matrix is screen-aligned it would convert the clip entry to
a window clip. Instead of doing this cogl-clip-stack.c now contains
the detection and keeps the entry as a rectangle clip but marks that
it is entirely described by its scissor rect. When flusing the clip
stack it doesn't do anything extra for entries that have this mark
(because the clip will already been setup by the scissor). This is
needed so that we can still track the original rectangle coordinates
and modelview matrix to help detect when it would be faster to modify
the rectangle when adding it to the journal rather than having to
break up the batch to set the clip state.

When logging a quad we now only store the 2 vertices representing the
top left and bottom right of the quad. The color is only stored once
per entry. Once we come to upload the data we expand the 2 vertices
into four and copy the color to each vertex. We do this by mapping the
buffer and directly expanding into it. We have to copy the data before
we can render it anyway so it doesn't make much sense to expand the
vertices before uploading and this way should save some space in the
size of the journal. It also makes it slightly easier if we later want
to do pre-processing on the journal entries before uploading such as
doing software clipping.
The modelview matrix is now always copied to the journal entry whereas
before it would only be copied if we aren't doing software
transform. The journal entry struct always has the space for the
modelview matrix so hopefully it's only a small cost to copy the
matrix.
The transform for the four entries is now done using
cogl_matrix_transform_points which may be slightly faster than
transforming them each individually with a call to
cogl_matrix_transfom.

The original patch triggered "maximize" when the window was dragged
to the top, so that the pointer was below or on the monitor edge and
above the work area's top.
If there's no chrome at the top of the monitor, so that monitor edge
and work area top fall together, the pointer cannot be moved above
the work area's top, so tiling was not triggered.
GTK is about to clean up its code and remove duplicate macros and
GdkDrawable usage. To prepare for that landing, we use the future-safe
versions of the same calls.

The old behavior of being able to shake loose a maximized window
overlaps with and is for the most part superceded by top edge tiling.
This commit changes the code to only enable shake loose behavior
when edge tiling is disabled.
https://bugzilla.gnome.org/show_bug.cgi?id=630548
In addition to the existing side-by-side tiling modes, this commit
adds a new "maximize" tiling mode. It allows the user to maximize
their windows (in other words, tile with the edge panels) by dragging
their window to the top edge of the monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=630548
The meta_window_handle_mouse_grab_op_event function ensures
the tile_mode variable is in a consistent state after a drag
op is finished.
The way this is current done is:
if (!window->maximized_vertically &&
window->tile_mode != META_TILE_NONE)
window->tile_mode = META_TILE_NONE;
While valid, it doesn't "read" as well as using the
META_WINDOW_TILED_SIDE_BY_SIDE macro, since the macro is specifically
about side-by-side tiling.
This commit just changes things to use the macro and to not bother
checking the tile mode (since if we just reset it anyway, then it doesn't
matter if the value is right or wrong to begin with).
https://bugzilla.gnome.org/show_bug.cgi?id=630548
Currently, the new tiling feature, supports side-by-side, horizontal
tiling when dragging windows to one of the vertical edges of a monitor.
Other types of tiling (on other monitor edges) are potentially useful,
though.
This commit renames the preference from side_by_side_tiling to
edge_tiling.
