+ EGL Extension #47
+
+Dependencies
+
+ Requires EGL 1.0
+
+ This extension is written against the wording of the EGL 1.4 Specification
+
+Overview
+
+ Android supports a number of different ANativeWindow implementations that
+ can be used to create an EGLSurface. One implementation, which is used to
+ send the result of performing window composition to a display, may have
+ some device-specific restrictions. Because of this, some EGLConfigs may
+ be incompatible with these ANativeWindows. This extension introduces a
+ new boolean EGLConfig attribute that indicates whether the EGLConfig
+ supports rendering to an ANativeWindow for which the buffers are passed to
+ the HWComposer HAL as a framebuffer target layer.
+
+New Types
+
+ None.
+
+New Procedures and Functions
+
+ None.
+
+New Tokens
+
+ Accepted by the <attribute> parameter of eglGetConfigAttrib and
+ the <attrib_list> parameter of eglChooseConfig:
+
+ EGL_FRAMEBUFFER_TARGET_ANDROID 0x3147
+
+Changes to Chapter 3 of the EGL 1.4 Specification (EGL Functions and Errors)
+
+ Section 3.4, Configuration Management, add a row to Table 3.1.

+
+ Section 3.4, Configuration Management, add a paragraph at the end of the
+ subsection titled Other EGLConfig Attribute Descriptions.
+
+ EGL_FRAMEBUFFER_TARGET_ANDROID is a boolean indicating whether the
+ config may be used to create an EGLSurface from an ANativeWindow for
+ which the buffers are to be passed to HWComposer as a framebuffer
+ target layer.
+
+ Section 3.4.1, Querying Configurations, change the last paragraph as follow
+
+ EGLConfigs are not sorted with respect to the parameters
+ EGL_BIND_TO_TEXTURE_RGB, EGL_BIND_TO_TEXTURE_RGBA, EGL_CONFORMANT,
+ EGL_LEVEL, EGL_NATIVE_RENDERABLE, EGL_MAX_SWAP_INTERVAL,
+ EGL_MIN_SWAP_INTERVAL, EGL_RENDERABLE_TYPE, EGL_SURFACE_TYPE,
+ EGL_TRANSPARENT_TYPE, EGL_TRANSPARENT_RED_VALUE,
+ EGL_TRANSPARENT_GREEN_VALUE, EGL_TRANSPARENT_BLUE_VALUE, and
+ EGL_RECORDABLE_ANDROID.
