- EGL Extension #XXX
-
-Extension Type
-
- EGL client extension
-
-Dependencies
-
- This extension is written against the wording of the 2014.08.27 revision
- of the EGL 1.5 Specification.
-
-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."
