[cogl/wip/cogl-1.12: 2/9] Adds libcogl-gles2 frontend GLES2 api



commit e6d7388c425390fd19311021497ecc4db18a2ce8
Author: Robert Bragg <robert linux intel com>
Date:   Sat Mar 24 01:41:48 2012 +0000

    Adds libcogl-gles2 frontend GLES2 api
    
    This adds a library that can be used instead of libGLESv2.so to provide
    symbols for the GLES 2.0 api. This can be used for convenience when
    using the cogl_gles2_context_ api since you don't need to manually go
    through a CoglGLES2Vtable when calling the gles2 api so it should be
    easier to port existing gles2 code to integrate with Cogl.
