e332236b87 cookbook: Added a longer slideshow example
Cross-fading between two images is straightforward,
but cycling between more than two is more efficient
if done by copying COGL textures between the
two textures, rather than trying to reposition the
textures.

The example demonstrates how to reuse a pair of
textures to cycle through multiple images.

c230fd8dfd cookbook: Made code examples more consistent
Modified the code example for the Clutter API version
of the cross-fade to use the same command line
as the COGL version.

This also simplifies the explanation in the recipe.

Also made the COGL code sample more consistent with
the Clutter API code sample.

83a8d0b3bb cookbook: Added example code for texture cross-fading
Added simple image viewer which loads image file names
from a directory, displays the first one, then displays
the next in the list with each key press. Uses the
primitive fade front in/fade back out approach.

Also adapted Emmanuele's example code which uses Cogl
to produce a similar effect, but within a single texture.
This code loads two images specified on the command
line and cross-fades between them.

c4913bfce9 Revert "build: Distclean generated ignore files"
Git ignore files are not dist'ed, so it's pointless to remove them on
distclean.

94c8635d0f build: Autogenerate more ignore files
The tests/accessibility, tests/micro-bench and the examples directory
in the coobook create a lot of non-installed binaries. Since we know who
they are, and we ignore them, we can auto-generate the ignore files as
well.

The rest of Clutter is covered by the main ignore file.

12031ca2c5 material: Implements weak materials
Weak materials are ones that don't take a reference on their parent and
they are associated with a callback that notifies when the material is
destroyed, because its parent was freed or modified.

More details can be found at:
http://wiki.clutter-project.org/wiki/CoglDesign/CoglMaterial

For now the concept is internal only but the plan is to make this public
at some point once we have tested the design internally.

01a7272599 cogl-shader: get_info_log should always use strdup
In the case where there is no error log for arbfp we were returning a
"" string literal. The other paths were using g_strdup to return a
string that could be freed with g_free. This makes the arbfp path return
g_strdup ("") instead.

b50bdd7919 cogl-shader: correctly #ifdef guard an if else block
There are quite a few if {} else {} blocks for dealing with arbfp else
glsl and the first block is guarded with #ifdef HAVE_COGL_GL. In this
case though the #endif was before the else so it wouldn't compile for
gles.

94692370d2 material-glsl: #include "cogl-shader-private.h"
We need to include cogl-shader-private.h to have the
COGL_SHADER_TYPE_GLSL define. When building for opengl this wasn't
noticed probably because some other header indirectly includes this
file. It was a problem when building for gles2 though.

c03544daa6 clutter-shader: use cogl_program_set_uniform_xyz API
Instead of using the deprecated cogl_program_uniform_xyz functions we
now use the cogl_program_set_uniform methods. It looks like this should
also fix a problem with clutter-shader too in that previously we weren't
calling cogl_program_use before cogl_program_uniform_xyz so setting
uniforms would only work while the shader is enabled.

f03037d580 cogl-program: Adds use_uniform_xyz methods
Instead of exposing an API that provides an OpenGL state machine style
where you first have to bind the program to the context using
cogl_program_use() followed by updating uniforms using
cogl_program_uniform_xyz we now have uniform setter methods that take an
explicit CoglHandle for the program.

This deprecates cogl_program_use and all the cogl_program_uniform
variants and provides the following replacements:
    cogl_program_set_uniform_1i
    cogl_program_set_uniform_1f
    cogl_program_set_uniform_int
    cogl_program_set_uniform_float
    cogl_program_set_uniform_matrix

2f54f8f0ea introspection: Use the --quiet flag conditionally
--quiet has been added to g-ir-scanner in the 0.9.1 cycle. We really
want to be able to compile clutter with 0.6.14 to be able to reuse
gir files that are distributed in current distributions.

Use the INTROSPECTION_SCANNER_ARGS (previously unused) variable to
convey --quiet when necessary.

db0c15aee8 cogl-atlas: Verify that the chosen initial size is supported
CoglAtlas chooses a fairly large default initial size of either
512x512 or 1024x1024 depending on the texture format. There is a
chance that this size will not be supported on some platforms which
would be catastrophic for the glyph cache because it would mean that
it would always fail to put any glyphs in the cache so text wouldn't
work. To fix this the atlas code now checks whether the chosen initial
size is supported by the texture driver and if not it will get halved
until it is supported.

b9f9ea3a9c cogl-atlas: Use _cogl_texture_driver_size_supported
Previously when creating a new rectangle map it would try increasingly
larger texture sizes until GL_MAX_TEXTURE_SIZE is reached. This is bad
because it queries state which should really be owned by the texture
driver. Also GL_MAX_TEXTURE_SIZE is often a conservative estimate so
larger texture sizes can be used if the proxy texture is queried
instead.

72029e14db cogl-rectangle-map: Record largest gap rather than the remaining space
Previously each node in the rectangle map tree would store the total
remaining space in all of its children to use as an optimization when
adding nodes. With this it could skip an entire branch of the tree if
it knew there could never be enough space for the new node in the
branch. This modifies that slightly to instead store the largest
single gap. This allows it to skip a branch earlier because often
there would be a lot of small gaps which would add up to enough a
space for the new rectangle, but the space can't be used unless it is
in a single node.

The rectangle map still needs to keep track of the total remaining
space for the whole map for the debugging output so this has been
added back in to the CoglRectangleMap struct. There is a separate
debugging function to verify this value.

2b5bb06bed cogl-atlas: Try the next size when there would be less than 6% waste
Previously when the atlas needs to be migrated it would start by
trying with the same size as the existing atlas if there is enough
space for the new texture. However even if the atlas is completely
sorted there will always be some amount of waste so when the atlas
needs to grow it would usually end up redundantly trying the same size
when it is very unlikely to fit. This patch changes it so that there
must be at least 6% waste available after the new texture is added
otherwise it will start with the next atlas size.

e080e824ee cogl-rectangle-map: Use a GArray for the stack
When iterating over the rectangle map a stack is used to implement a
recursive algorithm. Previously this was slice allocating a linked
list. Now it uses a GArray which is retained with the rectangle map to
avoid frequent allocations which is a little bit faster.
