42ed195f01
now stored in a separate struct so they can be stored for
application program objects as well.
* clutter/cogl/gles/cogl.c: Moved stub shader functions into
separate files.
(_cogl_features_init): Report support for the shaders feature on
GLES 2
* clutter/cogl/gles/cogl-shader.h:
* clutter/cogl/gles/cogl-shader.c:
* clutter/cogl/gles/cogl-program.h:
* clutter/cogl/gles/cogl-program.c: Separate files to handle
shaders on programs on GLES. If version 1.1 is being used then the
stub functions which all fail are still used.
* clutter/cogl/gles/cogl-gles2-wrapper.c
(cogl_gles2_wrapper_init, cogl_gles2_wrapper_bind_attributes),
(cogl_gles2_wrapper_get_uniforms): Move the uniforms and attribute
bindings into a separate function so they can be used to bind on
application shaders as well.
(cogl_gles2_wrapper_update_matrix): Now takes a parameter and is
no longer static so that it can be used to update all of the
matrices when a new shader is bound.
* clutter/cogl/gles/cogl-defines.h.in: Use GL_COMPILE_STATUS for
CGL_OBJECT_COMPILE_STATUS if the latter isn't available (for
example on GLES 2).
* clutter/cogl/gles/cogl-context.h (CoglContext): Added handle
arrays for programs and shaders.
* clutter/cogl/gles/cogl-context.c (cogl_create_context)
(cogl_destroy_context): Initialize and destroy program and shader
handle array.
* clutter/cogl/gles/Makefile.am (libclutter_cogl_la_SOURCES): Add
cogl-{shader,program}.{c,h}
