Creates a new, 4 component, attribute whose value remains constant across all the vertices of a primitive without needing to duplicate the value for each vertex.
The constants (value[0], value[1], value[2], value[3]) represent a 4 component float vector which should have a corresponding declaration in GLSL code like:
[| attribute vec4 name; |]
unless one of the built in names "cogl_color_in", "cogl_tex_coord0_in or "cogl_tex_coord1_in" etc is being used where no explicit GLSL declaration need be made.
