* clutter/cogl/gles/cogl-gles2-wrapper.c: All of the settings and
uniforms are now proxied into COGL variables instead of setting
the GL uniforms directly. Just before glDrawArrays is executed a
shader is generated using the given settings to avoid using 'if'
statements. The shaders are cached.
* clutter/cogl/gles/cogl-fixed-vertex-shader.glsl:
* clutter/cogl/gles/cogl-fixed-fragment-shader.glsl: The shaders
are now split into parts using comments instead of 'if' statements
so that the simplest shader can be generated on the fly.
* clutter/cogl/gles/stringify.sh: Now splits up the shader sources
into separate C strings where deliminated by special comments.
* clutter/cogl/gles/cogl-program.h:
* clutter/cogl/gles/cogl-program.c: A custom shader can no longer
be directly linked with the fixed-functionality replacement
because the replacement changes depending on the settings. Instead
the bound shader is linked with the appropriate replacement shader
just before glDrawArrays is executed. The custom uniform variables
must also be proxied through COGL variables because their location
can change when relinked.
(clutter_stage_egl_realize): Use ES 2 renderable type when
building for GLES 2.
* clutter/eglnative/clutter-event-egl.c (get_backend_time): Added
a NULL for the microseconds parameter of g_timer_elapsed.
* clutter/eglnative/clutter-stage-egl.h:
* clutter/eglnative/clutter-egl.h:
* clutter/eglnative/clutter-backend-egl.h: Include
clutter-egl-headers.h instead of including the GL headers directly
so it can include gl2.h when building for GLES 2.
* clutter/eglnative/clutter-egl-headers.h:
* clutter/eglnative/Makefile.am (libclutter_eglnative_la_SOURCES):
Added clutter-egl-headers.h
* clutter/cogl/gles/cogl-fixed-fragment-shader.glsl: GLES 2
doesn't provide a default precision for floats in the fragment
shader and it will reject the shader if there isn't one.
uniforms for alpha testing.
* clutter/cogl/gles/cogl-gles2-wrapper.c
(cogl_gles2_wrapper_init): Get the uniforms for alpha testing
settings.
(cogl_wrap_glEnable, cogl_wrap_glDisable): Enable/disable alpha
testing.
(cogl_wrap_glAlphaFunc): Filled in the wrapper.
* clutter/cogl/gles/cogl-fixed-fragment-shader.glsl: Added alpha
testing.
* clutter/cogl/gles/cogl-gles2-wrapper.h:
* clutter/cogl/gles/cogl-gles2-wrapper.c
(cogl_wrap_glGetIntegerv): Added a wrapper for glGetIntegerv so
that it can report zero clip planes.
* clutter/cogl/gles/cogl.c:
* clutter/cogl/gles/cogl-texture.c: Use the wrapped version of
glGetIntegerv
* clutter/cogl/gles/cogl-primitives.c (_cogl_path_fill_nodes): Use
_cogl_features_available to check for the stencil buffer instead
of an #ifdef. The stencil buffer is available in the default
profile for the GLES 2 simulator.
(cogl_gles2_wrapper_init): Get uniforms for fog parameters and
initialise them.
(cogl_wrap_glDrawArrays): Store the modelview matrix in a uniform
as well so that it can be used for fogging calculations.
(cogl_wrap_glEnable, cogl_wrap_glDisable): Enable/disable fogging.
(cogl_wrap_glFogx, cogl_wrap_glFogxv): Fill in wrapper to set
fogging parameters.
* clutter/cogl/gles/cogl-fixed-vertex-shader.glsl: Calculate the
fog amount if fogging is enabled.
* clutter/cogl/gles/cogl-fixed-fragment-shader.glsl: Mix with fog
color.
* clutter/cogl/gles/cogl-gles2-wrapper.h (CoglGles2Wrapper): Add
uniforms for fogging.
* clutter/eglx/clutter-stage-egl.h:
* clutter/eglx/clutter-egl-headers.h:
* clutter/eglx/clutter-backend-egl.h:
* clutter/eglx/Makefile.am: Include the GLES and EGL headers via
clutter-egl-headers.h so that the right version can be used
depending on whether the GLES 2 wrapper is being used.
* configure.ac: Added an automake conditional for whether the GLES
2 wrapper should be used.
* clutter/eglx/clutter-stage-egl.c (clutter_stage_egl_realize):
Remove the call to glGetIntegerv to get the max texture size. It
was being called before the GL context was bound so it didn't work
anyway and it was causing trouble for the GLES 2 simulator.
* clutter/cogl/gles/stringify.sh: Shell script to convert the
shaders into a C string.
* clutter/cogl/gles/cogl-gles2-wrapper.h:
* clutter/cogl/gles/cogl-gles2-wrapper.c: Wrappers for most of the
missing GL functions in GLES 2.
* clutter/cogl/gles/cogl-fixed-fragment-shader.glsl:
* clutter/cogl/gles/cogl-fixed-vertex-shader.glsl: New shaders for
GLES 2
* clutter/cogl/gles/cogl-defines.h.in: Use the @CLUTTER_GL_HEADER@
macro instead of always using the GLES 1 header.
* clutter/cogl/gles/cogl-context.h (CoglContext): Include a field
for the state of the GLES 2 wrapper.
* clutter/cogl/gles/cogl-texture.c:
* clutter/cogl/gles/cogl-primitives.c:
* clutter/cogl/gles/cogl.c: Use wrapped versions of the GL
functions where neccessary.
* clutter/cogl/gles/Makefile.am: Add sources for the GLES 2
wrapper and an extra build step to put the GLSL files into a C
string whenever the files change.
