As a bare minimum we want to ensure that are releases are able to build
with support for gles1, gles2, gl, egl and glx. Previously we only
checked the build with gl + glx enabled and our last release actually
missed a header file required for building with egl.
This adds CoglPipeline and CoglFramebuffer support for setting a color
mask which is a bit mask defining which color channels should be written
to the current framebuffer.
The final color mask is the intersection of the framebuffer color mask
and the pipeline color mask. The framebuffer mask affects all rendering
to the framebuffer while the pipeline masks can be used to affect
individual primitives.

The experimental 2.0 reference manual was setup with DOC_MODULE name of
"cogl" which conflicted with the 1.x API manual. This meant that when
running make install for both the reference manuals all the html files
would end up bundled together in the same location. The 2.0 API
reference now has a DOC_MODULE name of "cogl-2.0-experimental" the
corresponding -sections.txt and -docs.xml.in files have also been
renamed to match this.

There were several CoglOnscreen functions named like:
cogl_onscreen_<platform>_blah instead of cogl_<platform>_onscreen_blah
so this patch updates those to be consistent with other platform
specific apis we have in cogl.

This fixes the 2.0 reference manual Makefile to not ignore
cogl-context.h; it also adds cogl_context_new to cogl-sections.txt and
removes cogl_begin/end_gl. (For using raw GL with Cogl 2.0 the plan was
to add some API for creating additional GL contexts via some Cogl API
and a way to push/pop those contexts.)

we've got into a bit of a mess with how we name platform specific
symbols and files, so this is a first pass at trying to tidy that up.
All platform specific symbols should be named like
cogl_<platform>_symbol_name and similarly files should be named like
cogl-<platform>-filename.c

The recommended command to check for differences from master to the
remote master was using git log with a range from the local master to
the remote master but this wouldn't work if the local master is ahead
of the remote master because the range is backwards. This patch
changes it to recommend git diff --stat instead because then the
command would work even if the two branches have diverged.
Since gtk-doc is an optional dependency for Cogl then we need to special
case how EXTRA_DIST is initialized. It shouldn't be set when using
gtk-doc since gtk-doc.make expects to initialize EXTRA_DIST. If we
aren't using gtk-doc then it should be initialized to an empty value
instead of including gtk-doc.make so that the later lines that append
various extra png files to EXTRA_DIST won't fail.
This explicitly renames the cogl-2.0 reference manual to
cogl-2.0-experimental and renames the cogl-2.0 pkg-config file to
cogl-2.0-experimental.pc. Hopefully this should avoid
miss-understandings.
This exposes a CoglTexture2D typedef and adds the following experimental
API:
cogl_is_texture_2d
cogl_texture_2d_new_with_size
cogl_texture_2d_new_from_data
cogl_texture_2d_new_from_foreign
Since this is experimental API you need to define
COGL_ENABLE_EXPERIMENTAL_API before including cogl.h.
Note: With these new entrypoints we now expect a CoglContext pointer to
be passed in, instead of assuming there is a default context. The aim is
that for Cogl 2.0 we won't have a default context so this is a step in
that direction.
Automake seems a bit fragile when trying to do cunning things like
including a file with "-include". It does not recurse into that file (if
it exists) to generate the final Makefiles.
Let's add a if BUILD_GTK_DOC guard around the gtk-doc.make inclusion
instead, hopefully should work as intended.
Instead of simply extending the cogl_pipeline_ namespace to add api for
controlling the depth testing state we now break the api out. This adds
a CoglDepthState type that can be stack allocated. The members of the
structure are private but we have the following API to setup the state:
cogl_depth_state_init
cogl_depth_state_set_test_enabled
cogl_depth_state_get_test_enabled
cogl_depth_state_set_test_function
cogl_depth_state_get_test_function
cogl_depth_state_set_writing_enabled
cogl_depth_state_get_writing_enabled
cogl_depth_state_set_range
cogl_depth_state_get_range
This removes the following experimental API which is now superseded:
cogl_material_set_depth_test_enabled
cogl_material_get_depth_test_enabled
cogl_material_set_depth_test_function
cogl_material_get_depth_test_function
cogl_material_set_depth_writing_enabled
cogl_material_get_depth_writing_enabled
cogl_material_set_depth_range
cogl_material_get_depth_range
Once a CoglDepthState structure is setup it can be set on a pipeline
using cogl_pipeline_set_depth_state().
This is part of a broader cleanup of some of the experimental Cogl API.
One of the reasons for this particular rename is to switch away from
using the term "Array" which implies a regular, indexable layout which
isn't the case. We also want to strongly imply a relationship between
CoglBuffers and CoglIndexBuffers and be consistent with the
CoglAttributeBuffer and CoglPixelBuffer APIs.

This adds an experimental CoglEuler data type and the following new
functions:
cogl_euler_init
cogl_euler_init_from_matrix
cogl_euler_init_from_quaternion
cogl_euler_equal
cogl_euler_copy
cogl_euler_free
cogl_quaternion_init_from_euler
Since this is experimental API you need to define
COGL_ENABLE_EXPERIMENTAL_API before including cogl.h
This adds an experimental quaternion utility API. It's not yet fully
documented but it's complete enough that people can start to experiment
with using it. It adds the following functions:
cogl_quaternion_init_identity
cogl_quaternion_init
cogl_quaternion_init_from_angle_vector
cogl_quaternion_init_from_array
cogl_quaternion_init_from_x_rotation
cogl_quaternion_init_from_y_rotation
cogl_quaternion_init_from_z_rotation
cogl_quaternion_equal
cogl_quaternion_copy
cogl_quaternion_free
cogl_quaternion_get_rotation_angle
cogl_quaternion_get_rotation_axis
cogl_quaternion_normalize
cogl_quaternion_dot_product
cogl_quaternion_invert
cogl_quaternion_multiply
cogl_quaternion_pow
cogl_quaternion_slerp
cogl_quaternion_nlerp
cogl_quaternion_squad
cogl_get_static_identity_quaternion
cogl_get_static_zero_quaternion
Since it's experimental API you'll need to define
COGL_ENABLE_EXPERIMENTAL_API before including cogl.h.
Gtk-doc can be hard to install on Windows. This patch enables people wanting to
hack on Cogl itself from a Windows system to do so without the hassle to get
gtk-doc installed first.
This pulls in the experimental cogl 2.0 reference manual from the
clutter repository since it wasn't included in the filter-branch when we
split cogl out.
To allow us to have gobject properties that accept a CoglMatrix value we
need to register a GType. This adds a cogl_gtype_matrix_get_type function
that will register a static boxed type called "CoglMatrix".
This adds a new section to the reference manual for GType integration
functions.
This add two new function that allows us to transform or project an
array of points instead of only transforming one point at a time. Recent
benchmarking has shown cogl_matrix_transform_point to be a bottleneck
sometimes, so this should allow us to reduce the overhead when
transforming lots of vertices at the same time, and also reduce the cost
of 3 component, non-projective transforms.
For now they are marked as experimental (you have to define
COGL_ENABLE_EXPERIMENTAL_API) because there is some concern that it
introduces some inconsistent naming. cogl_matrix_transform_point would
have to be renamed cogl_matrix_project_point to be consistent, but that
would be an API break.
This exposes the idea of a stack of source materials instead of just
having a single current material. This allows the writing of orthogonal
code that can change the current source material and restore it to its
previous state. It also allows the implementation of new composite
primitives that may want to validate the current source material and
possibly make override changes in a derived material.
This adds a "Cogl deprecated API" chapter to the Cogl reference manual
so we can group all the documentation for deprecated symbols together
instead of having them clutter up the documentation of symbols we would
rather developers used.
The CoglTexture3D API is only available when defining
COGL_ENABLE_EXPERIMENTAL_API so it should be listed in the experimental
section of the API reference.
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
