-Unlike --enable-gles-overlay

-one big library that supports multiple APIs.
This option enables OpenGL ES as separate libraries. This is an alternative
+approach to enable OpenGL ES. It is only supported by
+egl_gallium

+Explicitly enable or disable egl_gallium

This variable specifies the native platform. The valid values are the same
as those for --with-egl-platforms
. When the variable is not set,
the main library uses the first platform listed in
---with-egl-platforms
as the native platform
--with-egl-platforms
as the native platform.
+
+Extensions like EGL_MESA_drm_display
define new functions to
+create displays for non-native platforms. These extensions are usually used by
+applications that support non-native platforms. Setting this variable is
+probably required only for some of the demos found in mesa/demo repository.
egl_dri2
+
+This driver supports both x11
and drm
platforms.
+It functions as a DRI2 driver loader. For x11
support, it talks
+to the X server directly using (XCB-)DRI2 protocol.
