94e2c7a949 build: Generate ClutterJson in the top directory
Instead of doing the shlib trick, build ClutterJson (if needed) inside
the top-level clutter/ directory - similar to a non-recursive layout.

Hopefully, one day, we'll be able to do this with a real non-recursive
layout.

4ee05f8e21 keysyms: Update the macros to CLUTTER_KEY_*
The keysyms defines in clutter-keysyms.h are generated from the X11 key
symbols headers by doing the equivalent of a pass of sed from XK_* to
CLUTTER_*. This might lead to namespace collisions, down the road.
Instead, we should use the CLUTTER_KEY_* namespace.

This commit includes the script, taken from GDK, that parses the X11
key symbols and generates two headers:

  - clutter-keysyms.h: the default included header, with CLUTTER_KEY_*
  - clutter-keysyms-compat.h: the compatibility header, with CLUTTER_*

The compat.h header file is included if CLUTTER_DISABLE_DEPRECATED is
not defined - essentially deprecating all the old key symbols.

This does not change any ABI and, assuming that an application or
library is not compiling with CLUTTER_DISABLE_DEPRECATED, the source
compatibility is still guaranteed.

edb54574fa build: Disable deprecated API when building Clutter
Make sure we don't use deprecated API internally by adding
CLUTTER_DISABLE_DEPRECATED to the AM_CPPFLAGS.

This requires adding -UCLUTTER_DISABLE_DEPRECATED to the introspection
scanner CFLAGS, otherwise the deprecated API will never be introspected
and the data generated will not be compatible.

f7854dd90f introspection: Build fixes
This patch merges in substantial work from
Emmanuele Bassi <ebassi@linux.intel.com>

* Use new introspection --include-uninstalled API since we don't want
  to try to find the clutter-1.0.pc file before it's installed.
* Use --pkg-export for Clutter-1.0.gir, since we want the .gir file to
  contain the associated pkg-config file.
* Drop the use of --pkg for dependencies; those come from the associated
  .gir files.  (Actually, --pkg is almost never needed)
* Add --quiet

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.

d14e294d86 Add ClutterTableLayout, a layout showing children in rows and columns
A TableLayout is a layout manager that allocates its children in rows
and columns. Each child is assigned to a cell (or more if a cell span
is set).

The supported child properties are:

  • x-expand and y-expand: if this cell with try to allocate the
    available extra space for the table.
  • x-fill and y-fill: if the child will get all the space available in
    the cell.
  • x-align and y-align: if the child does not fill the cell, then
    where the child will be aligned inside the cell.
  • row-span and col-span: number of cells the child will allocate for
    itself.

Also, the TableLayout has row-spacing and col-spacing for specifying
the space in pixels between rows and between columns.

We also include a simple test of the layout manager, and the
documentation updates.

The TableLayout was implemented starting from MxTable and
ClutterBoxLayout.

The Clutter Accessibility Library is an implementation of the ATK,

tools. This allows not only writing accessible user interfaces, but also
allows testing and verification frameworks based on A11Y technologies to
inspect and test a Clutter scene graph.

3734408962 Use -Bsymbolic-functions
The -Bsymbolic-functions linker flag allows to avoid intra-library
PLT jumps on ELF platforms. It is similar to the aliasing hack in
GLib and GTK+, but definitely less messy.

The configure script should look for the flags, in order to support
platforms/linkers that do not have it.

bf9d5f3949 build: distinguish CLUTTER_WINSYS and CLUTTER_SONAME_INFIX
This adds a separate variable name "CLUTTER_SONAME_INFIX" to define the
infix for the clutter library that gets linked. Currently the WINSYS
corresponds to the directory we enter when building to compile the
window system and input support, but it is desirable to be able to
define multiple flavours that use the same WINSYS but should result in
different library names.

For example we are planning to combine the eglx and eglnative window
systems into one "egl" winsys but we will need to preserve the current
library names for the eglx and eglnative flavours.

c2081a076c effect: Add DeformEffect
DeformEffect is an abstract class that should be used to write effects
that change the geometry of an actor before submitting it to the GPU.

Just like the ShaderEffect class, DeformEffect renders the actor to
which it has been applied into an FBO; then it creates a mesh and stores
it inside a VBO. Sub-classes can control vertex attributes like
position, texel coordinates and the color.

5a5b21446c effect: Add BlurEffect
A simple, GLSL shader-based blur effect.

The blur shader is taken straight from the test-shader.c interactive

implementation of a box blur, but it's all we have right now until I
figure out a way to do multi-pass shading with the current API.

c260da79e3 effect: Add ShaderEffect
The ShaderEffect class is an abstract base type for shader-based
effects. GLSL-based effects should be implemented by sub-classing
ShaderEffect and overriding ActorMeta::set_actor() to set the source
code of the shader, and Effect::pre_paint() to update the uniform
values, if any.

The ShaderEffect has a generic API for sub-classes to set the values
of the uniforms defined by their shaders, and it uses the shader
types we defined for ClutterShader, to avoid re-inventing the wheel
every time.

c3ab32ae68 effect: Add OffscreenEffect
The OffscreenEffect class is meant to be used to implement Effect
sub-classes that create an offscreen framebuffer and redirect the
actor's paint sequence there. The OffscreenEffect is useful for
effects using fragment shaders.

Any shader-based effect being applied to an actor through an offscreen
buffer should be used before painting the resulting target material and
not for every actor. This means that doing:

       pre_paint: cogl_program_use(program)
                  set up offscreen buffer
           paint: [ actors ] → offscreen buffer → target material
      post_paint: paint target material
                  cogl_program_use(null)

Is not correct. Unfortunately, we cannot really do:

      post_paint: cogl_program_use(program)
                  paint target material
                  cogl_program_use(null)

Because the OffscreenEffect::post_paint() implementation also pops the
offscreen buffer and re-instates the previous framebuffer:

      post_paint: cogl_program_use(program)
                  change frame buffer ← ouch!
                  paint target material
                  cogl_program_use(null)

One way to fix it is to allow using the shader right before painting
the target material - which means adding a new virtual inside the
OffscreenEffect class vtable in additions to the ones defined by the
parent Effect class.

The newly-added paint_target() virtual allows the correct sequence of
actions by adding an entry point for sub-classes to wrap the "paint
target material" operation with custom code, in order to implement the
case above correctly as:

      post_paint: change frame buffer
                  cogl_program_use(program)
                  paint target material
                  cogl_program_use(null)

The added upside is that sub-classes of OffscreenEffect involving
shaders really just need to override the prepare() and paint_target()
virtuals, since the pre_paint() and post_paint() do all that's needed.

a86f1b45bb Add the ClutterEffect abstract class
ClutterEffect is an abstract class that should be used to apply effects
on generic actors.

The ClutterEffect class just defines what an effect should implement; it
could be defined as an interface, but we might want to add some default
behavior dependent on the internal state at a later point.

The effect API applies to any actor, so we need to provide a way to
assign an effect to an actor, and let ClutterActor call the Effect
methods during the paint sequence.

Once an effect is attached to an actor we will perform the paint in this
order:

  • Effect::pre_paint()
  • Actor::paint signal emission
  • Effect::post_paint()

Since an effect might collide with the Shader class, we either allow a
shader or an effect for the time being.
