[cogl/wip/cogl-sharp: 12/51] cogl-sharp: Expose CoglPixelFormat

[Damien Lespiau <dlespiau src gnome org>]

commit 47bb9404685ea4bdfd6009fc56ac64cbde0fbf31
Author: Damien Lespiau <damien lespiau intel com>
Date:   Mon Oct 1 21:10:10 2012 +0100

    cogl-sharp: Expose CoglPixelFormat
    
    And thus also enable the generation of yet another method of
    FrameBuffer.
    
    This also introduces a way to tell the generator you want the enum
    members to bo upper case (by default it will generate capitalized enum
    values).
