+Number
+
+ EGL Extension #145
+
+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. See also GLX_SGIX_visual_select_group.
+
+New Types
+
+ None
+
+New Procedures and Functions
+
+ None
+
+New Tokens
+
+ Accepted as a new EGLConfig attribute:
+
+ EGL_CONFIG_SELECT_GROUP_EXT 0x34C0
+
+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_EXT | 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_EXT 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_EXT 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_EXT | 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_EXT."
