Some minor fixes here and there: missing include, wrongly placed #endif,
unused variable warning fixes, missing #ifdef.
Make ClutterStageEGL a subclass of either ClutterStageX11 or GObject
depending if you compile with X11 support (EGLX) or not (native).
We need to include cogl-shader-private.h to have the
COGL_SHADER_TYPE_GLSL define. When building for opengl this wasn't
noticed probably because some other header indirectly includes this
file. It was a problem when building for gles2 though.
This makes CoglProgram/Shader automatically detect when the user has
given an ARBfp program by checking for "!!ARBfp1.0" at the beginning of
the user's source.
ARBfp local parameters can be set with cogl_program_uniform_float
assuming you pass a @size of 4 (all ARBfp program.local parameters
are vectors of 4 floats).
This doesn't expose ARBfp environment parameters or double precision
local parameters.
This makes the gles2 cogl_program_use consistent with the GL version by
not binding the program immediately and instead leaving it to
cogl-material.c to bind the program when actually drawing something.
The commit to split the fragment processing backends out from
cogl-material.c (3e1323a636) broke the GLES 1 and 2 builds the
fix was to guard the code in each backend according to the
COGL_MATERIAL_BACKEND_XYZ defines which are setup in
cogl-material-private.h.
This splits the fragment processing backends (glsl, arbfp and fixed) out
from cogl-material.c into their own cogl-material-{glsl,arbfp,fixed}.c
files in an effort to help and keep cogl-material.c maintainable.
