we are doing the same (Alejandro)

* Remove redundant 'struct active_xfb_varying'
* Update several comments, including spec quotes if needed
* Rename struct 'active_xfb_varying_array' to 'active_xfb_varyings'
* Rename variable 'array' to 'active_varyings'
* Replace one if condition for an assert (<MAX_FEEDBACK_BUFFERS)
* Remove BufferMode initialization (was already done)
