bcd4385a0e test-conform: Delay initializing Clutter until a test is run
Instead of calling clutter_init immediately, test-conformance now only
calls it as part of test_conform_simple_fixture_setup. The conformance
tests assert that only one test is run per instance of
test-conformance so it should never end up calling clutter_init
twice. Delaying clutter_init has the advantage that calling
"test-conformance -l" will still work even on systems with no X
server. This could be useful for automated build systems.

cefc0e381b Add a conformance test for 3D textures
This creates a 3D texture with different colors on all of the images
and renders it using a VBO to verify that the texture coordinates can
select all of the images.

972c0c24f0 Add a conformance test for cogl_texture_{get_data,set_region}
This verifies that calling cogl_texture_get_data returns the same data
uploaded to the texture. The bottom quarter of the texture is replaced
using cogl_texture_set_region. It tries creating the texture with
different sizes and flags in the hope that it will hit different
texture backends.

c434f1fc48 material: Make CoglMaterial responsible for depth state
This redirects the legacy depth testing APIs through CoglMaterial and
adds a new experimental cogl_material_ API for handling the depth
testing state.

This adds the following new functions:
cogl_material_set_depth_test_enabled
cogl_material_get_depth_test_enabled
cogl_material_set_depth_writing_enabled
cogl_material_get_depth_writing_enabled
cogl_material_set_depth_test_function
cogl_material_get_depth_test_function
cogl_material_set_depth_range
cogl_material_get_depth_range

As with other experimental Cogl API you need to define
COGL_ENABLE_EXPERIMENTAL_API to access them and their stability isn't
yet guaranteed.

4c22f122e1 script: Support layout manager properties
Layout properties work similarly to child properties, with the added
headache that they require the 3-tuple:

  ( layout manager, container, actor )

to be valid in order to be inspected, parsed and applied. This means
using the newly added back-pointer from the container to the layout
manager and then rejigging a bit how the ScriptParser handles the
unresolved properties.

Similarly to the child properties, which use the "child::" prefix, the
layout manager properties use the "layout::" prefix and are defined with
the child of a container holding a layout manager.

589c8d9579 [texture] Support picking textures according to their alpha channel
This adds a boolean "pick-with-alpha" property to ClutterTexture and when
true, it will use the textures alpha channel to define the actors shape when
picking.

Users should be aware that it's a bit more expensive to pick textures like
this (so probably best not to blindly enable it on *all* your textures)
since it implies rasterizing the texture during picking whereas we would
otherwise just send a solid filled quad to the GPU.  It will also interrupt
the internal batching of geometry for pick renders which can otherwise often
be done in a single draw call.

a12a2e591b Add a conformance test for ClutterCairoTexture
This adds a simple test for ClutterCairoTexture that draws two
rectangles to the cairo surface in an idle callback and then verifies
that they appeared at the right colours in the paint callback. If that
succeeds then the second time the idle callback is invoked it will
replace one of the rectangles with a sub region update and the
following paint callback will again verify the rectangles.

08a4995383 tests: Add a conformance test for the wrap modes of a cogl material
This renders a texture using different combinations of wrap modes for
the s and t coordinates and then verifies that the expected wrapping
is acheived. The texture is drawn using rectangles, polygons and
vbos. There is also code to test a rectangle using an atlased texture
(which should test the manual repeating) however the validation for
this is currently disabled because it doesn't work.

830f2402d4 Merge branch 'more-texture-backends'
This adds three new texture backends.

- CoglTexture2D: This is a trimmed down version of CoglTexture2DSliced
  which only supports a single texture and only works with the
  GL_TEXTURE_2D target. The code is a lot simpler so it has a less
  overheads than dealing with slices. Cogl will use this wherever
  possible.

- CoglSubTexture: This is used to get a CoglHandle to represent a
  subregion of another texture. The texture can be used as if it was a
  standalone texture but it does not need to copy the resources.

- CoglAtlasTexture: This collects RGB and RGBA textures into a single
  GL texture with the aim of reducing texture state changes and
  increasing batching. The backend will try to manage the atlas and
  may move the textures around to close gaps in the texture. By
  default all textures will be placed in the atlas.

36f18e5ac5 cogl: Make CoglSubTexture only work for quad rendering
The sub texture backend doesn't work well as a completely general
texture backend because for example when rendering with cogl_polygon
it needs to be able to tranform arbitrary texture coordinates without
reference to the other coordintes. This can't be done when the texture
coordinates are a multiple of one because sometimes the coordinate
should represent the left or top edge and sometimes it should
represent the bottom or top edge. For example if the s coordinates are
0 and 1 then 1 represents the right edge but if they are 1 and 2 then
1 represents the left edge.

Instead the sub-textures are now documented not to support coordinates
outside the range [0,1]. The coordinates for the sub-region are now
represented as integers as this helps avoid rounding issues. The
region can no longer be a super-region of the texture as this
simplifies the code quite a lot.

There are two new texture virtual functions:

transform_quad_coords_to_gl - This transforms two pairs of coordinates
     representing a quad. It will return FALSE if the coordinates can
     not be transformed. The sub texture backend uses this to detect
     coordinates that require repeating which causes cogl-primitives
     to use manual repeating.

ensure_non_quad_rendering - This is used in cogl_polygon and
     cogl_vertex_buffer to inform the texture backend that
     transform_quad_to_gl is going to be used. The atlas backend
     migrates the texture out of the atlas when it hits this.

95d78acb4c script: Allow parsing child properties
The ClutterScript parser needs to be extended to parse child properties
and apply them after an actor has been added to a container. In order to
distinguish child properties from regular GObject properties we can use
the "child::" prefix, e.g.:

  {
    "type" : "ClutterRectangle",
    "id" : "child-01",
    "child::has-focus" : true,
    ...
  }

Parsing child properties can be deferred to the ClutterScriptable
interface, just like regular properties.

d7cfa15851 conform: Add the beginnings of a ClutterScript test suite
ClutterScript is a very complicated piece of machinery, with a

want to introduce regressions or break existing ClutterScript
definitions, we'd better have a conformance test suite.

7d891d9dd4 tests: Allow getting data files from the tests/data directory
The units under the conformance test suite should be able to use
external files. Linking the files in tests/conform like the
interactive tests do seems like a hack piled on top of a hack, so
instead we should provide a programmatic way for a conformance
test unit to get the full path of a file, regardless of where the
tests/data directory is.

We can use a define to get the full path of tests/data and then
a function using g_build_filename() to construct the path to the
file we want.

 - A regular onscreen source with a clone next to it

 - An offscreen source with a clone. This is currently commented out

 - An onscreen source with a rectangular clip and a clone.

 - An onscreen source with a clip from a path and a clone.

The sources are all a 2x2 grid of colors. Each clone is tested that it
either contains the color that should be at that grid position or that
the stage color is showing through if the source is clipped.

83b4ec7a12 units: Cache the pixels value inside Units
When computing the pixels value of a ClutterUnits value we should
be caching the value to avoid recomputing for every call of
clutter_units_to_pixels(). We already have a flag telling us to
return the cached value, but we miss the mechanism to evict the
cache whenever the Backend settings affecting the conversion, that
is default font and resolution, change.

In order to implement the eviction we can use a "serial"; the
Backend will have an internal serial field which we retrieve and
put inside the ClutterUnits structure (we split one of the two
64 bit padding fields into two 32 bit fields to maintain ABI); every
time we call clutter_units_to_pixels() we compare the units serial
with that of the Backend; if they match and pixels_set is set to
TRUE then we just return the stored pixels value. If the serials
do not match then we unset the pixels_set flag and recompute the
pixels value.

We can verify this by adding a simple test unit checking that
by changing the resolution of ClutterBackend we get different
pixel values for 1 em.

Fixes and adds a unit test for creating and drawing using materials with

_cogl_material_flush_layers_gl_state will bind the fallback texture for any

current blend mode does't actually reference a texture source in which case
binding the fallback texture is redundant.

41579eb3c9 [test-premult] Adds a unit test for texture upload premultiplication semantics
cogl_texture_new_from_data lets you specify a source format for the users given
data, and an internal format which the user wants the GPU to see. This unit
test verifies that the users data is premultiplied, un-premultiplied or
left alone for a number of (source format, internal format) pairs.

cogl_texture_set_region allows specifying a source format, and the internal
format is determined from the texture being updated. As above we test
a number of format pairs and check Cogl is converting data correctly.

The test verifies that if the user allows COGL_FORMAT_ANY for the
internal_format then by default Cogl will choose a premultipled format for
RGBA textures.

Note: Currently this only tests cogl_texture_new_from_data and
cogl_texture_set_region, we should also test cogl_texture_new_from_file,
cogl_texture_new_from_bitmap and cogl_texture_new_from_foreign.
