8bdfa4ddee cookbook: Recipe for "looping animations"
Added a recipe giving examples of how to loop
animations for each part of the animation API (implicit,
animator, state).

The discussion covers looping a fixed number of times
and inverting a single implicit animation to create
a loop which goes back to its start on each iteration.

9249bd8411 xsettings: don't use the xsettings watch function functionality
The "watch" function functionality in xsettings-client.c is designed
for setups like GDK where filters are per-window. If we are going
to pass all events to _clutter_xsettings_client_process_event()
anyways, we can just pass in NULL for watch.

This avoids a nasty infinite loop where an event would get processed
triggering removing a filter and adding a new filter, which would
immediately run and remove a filter and add another and so on
ad-infinitum.

1bcf15e1b8 cogl-texture: Remove the gl_handle from CoglTextureSliceCallback
There's no longer any need to use the GL handle in the callback for
_cogl_texture_foreach_sub_texture_in_region because it can now work in
terms of primitive cogl textures so it has now been removed. This
would be helpful if we ever want to make the foreach function public
so that apps could implement their own primitives using sliced
textures.

49898d43dd cogl-pipeline: Use layer overrides as CoglHandles instead of GLuint
Since d5634e37 the sliced texture backend now works in terms of
CoglTexture2Ds so there's no need to have special casing for
overriding the texture of a pipeline layer with a GL handle. Instead
we can just use cogl_pipeline_set_layer_texture with the
CoglHandle. The special _cogl_pipeline_set_layer_gl_texture_slice
function has now been removed and parts of the code for comparing
materials have been simplified.

1447ceb0de CoglTexture2DSliced: Pass slice tex to callback in foreach_sub_texture
The cogl_texture_foreach_sub_texture_in_region virtual for the sliced
texture backend was previously passing the CoglHandle of the sliced
texture to the callback. Since d5634e37 the slice texture backend now
works in terms of 2D textures so it's possible to pass the underlying
slice texture as a handle too. This makes all of the foreach callbacks
consistent in that they pass a CoglHandle of the primitive texture
type that matches the GL handle.

21c7403011 docs: Adds an initial cogl-2.0 reference manual
So we can keep track of the experimental progress of Cogl 2.0 features
this adds a standalone Cogl 2.0 Reference Manual which doesn't cover
the deprecated 1.x symbols and removes the need for a "Cogl
experimental API" chapter since those sections now make up the main
table of contents.

fb9d3a8350 path 2.0: update path API for experimental 2.0 API
When COGL_ENABLE_EXPERIMENTAL_2_0_API is defined cogl.h will now include
cogl2-path.h which changes cogl_path_new() so it can directly return a
CoglPath pointer; it no longer exposes a prototype for
cogl_{get,set}_path and all the remaining cogl_path_ functions now take
an explicit path as their first argument.

The idea is that we want to encourage developers to retain path objects
for as long as possible so they can take advantage of us uploading the
path geometry to the GPU. Currently although it is possible to start a
new path and query the current path, it is not convenient.

The other thing is that we want to get Cogl to the point where nothing
depends on a global, current context variable. This will allow us to one
day define a sensible threading model if/when that is ever desired.

8efb48ecf4 config.h: define COGL_ENABLE_EXPERIMENTAL_2_0_API
By defining COGL_ENABLE_EXPERIMENTAL_2_0_API in config.h we can ensure
that all internal clutter and cogl code can use the Cogl 2.0 API and by
not using AM_CPPFLAGS we avoid having other tools such as glib-mkenums
and the gir-scanner from inadvertently using the define also.

b993195dc8 cogl: Adds COGL_ENABLE_EXPERIMENTAL_2_0_API define
For now this new define is simply an alias for
COGL_ENABLE_EXPERIMENTAL_API but the intention is that we will also use
it to start experimenting with changes that need to break the existing
Cogl API in incompatible ways.

985518c601 color: Add named, global colors
Since EGA colors are apparently all the rage in other toolkits, Clutter
should not be left out. On top of the usual CGA/EGA palette the static
colors also include the Tango Icon palette, which at least is more
pleasant to the eye.

Static colors are accessed through an enumeration by using
clutter_color_get_static(), or using the short-hand pre-processor
macros.

5f30835eae cogl-shader: Prepend boilerplate for portable shaders
We now prepend a set of defines to any given GLSL shader so that we can
define builtin uniforms/attributes within the "cogl" namespace that we
can use to provide compatibility across a range of the earlier versions
of GLSL.

This updates test-cogl-shader-glsl.c and test-shader.c so they no longer
needs to special case GLES vs GL when splicing together its shaders as
well as the blur, colorize and desaturate effects.

To get a feel for the new, portable uniform/attribute names here are the
defines for OpenGL vertex shaders:

 #define cogl_position_in gl_Vertex
 #define cogl_color_in gl_Color
 #define cogl_tex_coord_in  gl_MultiTexCoord0
 #define cogl_tex_coord0_in gl_MultiTexCoord0
 #define cogl_tex_coord1_in gl_MultiTexCoord1
 #define cogl_tex_coord2_in gl_MultiTexCoord2
 #define cogl_tex_coord3_in gl_MultiTexCoord3
 #define cogl_tex_coord4_in gl_MultiTexCoord4
 #define cogl_tex_coord5_in gl_MultiTexCoord5
 #define cogl_tex_coord6_in gl_MultiTexCoord6
 #define cogl_tex_coord7_in gl_MultiTexCoord7
 #define cogl_normal_in gl_Normal

 #define cogl_position_out gl_Position
 #define cogl_point_size_out gl_PointSize
 #define cogl_color_out gl_FrontColor
 #define cogl_tex_coord_out gl_TexCoord

 #define cogl_modelview_matrix gl_ModelViewMatrix
 #define cogl_modelview_projection_matrix gl_ModelViewProjectionMatrix
 #define cogl_projection_matrix gl_ProjectionMatrix
 #define cogl_texture_matrix gl_TextureMatrix

And for fragment shaders we have:

 #define cogl_color_in gl_Color
 #define cogl_tex_coord_in gl_TexCoord

 #define cogl_color_out gl_FragColor
 #define cogl_depth_out gl_FragDepth

 #define cogl_front_facing gl_FrontFacing

57633520d4 Make test-cogl-npot-texture a bit more extensive
The size of the texture used for test-cogl-npot-texture was only using
1 pixel of waste and the texture was scaled down so it would be quite
likely that the test would still pass if only the top left slice was
rendered. It also didn't test using non-default texture
coordinates. These problems made it fail to pick up bug 2398. The
texture is now using the maximum amount of waste and rendered in four
parts at 1:1 scale.

cc63c7dd8f cogl-texture-2d-sliced: Fix the foreach callback for waste textures
When converting the virtual coordinates of the underlying texture for
a slice to virtual coordinates for the whole texture it was using the
size and offset of the intersection as the size of the child
texture. This would be incorrect if the texture contains waste or the
texture coordinates are not the default. Instead the sliced foreach
function now passes the CoglSpan to the callback instead of the
intersection.

8112bfc49f Replace the disable-npots tool with a COGL_DEBUG option
Previously in the tests/tools directory we build a disable-npots
library which was used as an LD_PRELOAD to trick Cogl in to thinking
there is no NPOT texture extension. This is a little awkward to use so
it seems much simpler to just define a COGL_DEBUG option to disable
npot textures.

632412c9c8 actor: Check "paint" handlers in _get_paint_volume
Instead of waiting until clutter_actor_paint to check if there are any
handlers connected to the "paint" signal, we now do the check whenever
the paint-volume is requested in _actor_get_paint_volume_mutable().

Previously we checked in clutter_actor_paint(), but at that time we may
already be using a stage clip that could be derived from an invalid
paint-volume. We used to try and handle that by queuing a follow up,
unclipped, redraw but anyway there was an additional problem with the
previous approach because the checking wasn't enough to always catch
invalid volumes involved in culling (considering that containers may
derive their volume from children that haven't yet been painted)

By moving the check to _get_paint_volume time not only do we now
correctly check children in cases where a container derives its volume
from its children's volumes but we no longer need to queue follow up
redraws to cover up artefacts.

Since we now never queue follow up redraws, this in turn means we should
no longer clobber redraws queued with an explicit clip which was
something affecting gnome-shell since it connects a handler to the paint
signal of the stage.

844b578128 matrix-stack: use GArray instead of GSList for stack
In some micro-benchmarks testing journal throughput the list
manipulation jumps pretty high in the profile. This replaces the GSList
usage with a GArray instead which is effectively a grow only allocation
that means we avoid ongoing allocations while manipulating the stack

a6000533dc pipeline: Avoid costly checking of lighting properties
During _cogl_pipeline_needs_blending_enabled we were always checking the
current lighting properties (ambient,diffuse,specular,emission) which
had a notable impact during micro-benchmarks that exercise journal
throughput of simple colored rectangles. This #if 0's the offending code
considering that Cogl doesn't actually support lighting currently and
when it actually does then we will be able to optimize this by avoiding
the checks when lighting is disabled.

eaee5dd604 cogl: add separate material for blended source_colors
When using cogl_set_source_color4ub there is a notable difference
between colors that require blending and those that dont. When trying to
modify the color of pipeline referenced by the journal we don't force a
flush of the journal unless the color change will also change the
blending state. By using two separate pipeline objects for handing
opaque or transparent colors we can avoid ever flushing the journal when
repeatedly using cogl_set_source_color and jumping between opaque and
transparent colors.
