This makes it possible to create vertex attributes that efficiently represent constant values without duplicating the constant for every vertex. This adds the following new constructors for constant attributes: cogl_attribute_new_const_1f cogl_attribute_new_const_2fv cogl_attribute_new_const_3fv cogl_attribute_new_const_4fv cogl_attribute_new_const_2f cogl_attribute_new_const_3f cogl_attribute_new_const_4f cogl_attribute_new_const_2x2fv cogl_attribute_new_const_3x3fv cogl_attribute_new_const_4x4fv Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit 6507216f8030e84dcf2e63b8ecfe906ac47f2ca7)

* @name: a unique symbol name for this feature
|
|

|
|
* @gles_availability: flags to specify which versions of GLES the

|
|
*
|
|
* @extension_suffixes: A zero-separated list of suffixes in a
