           Summary: Expose more ES extensions that are identical to
                    existing desktop GL functionality
           Product: Mesa
           Version: git
          Platform: All
               URL: http://www.khronos.org/registry/gles/
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: medium
         Component: Mesa core
        AssignedTo: mesa-dev at lists.freedesktop.org
        ReportedBy: idr at freedesktop.org


There are a bunch of OpenGL ES 2.0 extensions, primarily vendor extensions,
that expose existing desktop GL functionality in ES.  Since Mesa is full
desktop GL, we should expose as many of these as possible in ES "mode." 
Scanning the list in the ES registry and mesa/main/extensions.c, it looks like
the following could be trivially added:

  GL_APPLE_texture_2D_limited_npot
  GL_EXT_shader_texture_lod
  GL_EXT_read_format_bgra
  GL_APPLE_framebuffer_multisample
  GL_APPLE_texture_format_BGRA8888
  GL_APPLE_texture_max_level
  GL_ARM_rgba8
  GL_ANGLE_framebuffer_blit
  GL_ANGLE_framebuffer_multisample
  GL_EXT_frag_depth
