>Overview
>
>    This extension provides a mechanism to lower the config selection priority 
>    of the configs returned by eglChooseConfig. A new config attribute is
>    introduced, providing a way for the implementation to group configs into 
>    different config selection categories.  The config selection priorities of
>    all the configs in one category may be higher or lower than the ones in 
>    other categories.  The config selection priorities in one category follow 
>    the rules of eglChooseConfig.

>Additions to the EGL 1.5 Specification
>
>    In section 3.4 "Configuration Management", under the "Buffer Descriptions
>    and Attributes" heading, append to table 3.1 the following:
>    
>    "EGL_CONFIG_SELECT_GROUP_MESA | integer | the config select group" 
>    
>    In section 3.4 "Configuration Management", under the "Other EGLConfig
>    Attribute Descriptions" heading, append to the end the following:
>
>    "The attribute EGL_CONFIG_SELECT_GROUP_MESA is used to specify the config
>    selection category of the config. Configs in the i-th category have a higher
>    config selection priority than those found in the (i+1)-th category.
>    
>    "The attribute EGL_CONFIG_SELECT_GROUP_MESA is used by the implementation to
>    override the default sorting rules, by collecting configurations into 
>    groups. It is not accepted by the <attrib_list> parameter of 
>    eglChooseConfig, but it is accepted as the <attribute> in 
>    eglGetConfigAtrrib." 
>    
>    In section 3.4 "Configuration Management", under the "Sorting of EGLConfigs"
>    heading, append to table 3.4 the following: 
>    
>    "EGL_CONFIG_SELECT_GROUP_MESA | 0 | Ignore | Smaller | 0" 
>    
>    In section 3.4 "Configuration Management", under the "Sorting of EGLConfigs"
>    heading, append before the list entry which starts with "1. Special: by
>    EGL_CONFIG_CAVEAT" the following entry:
>
>    "0. Smaller EGL_CONFIG_SELECT_GROUP_MESA."
