EGL Extension #46

Requires EGL 1.4

Written against the EGL 1.4 specification.

NVIDIA 3D Vision provides stereoscopic 3d rendering without
requiring applications to change their rendering methods. However
there are cases where applications can benefit from adjusting 3D
vision parameters directly to experiment with this functionality in
applications not yet known to 3D Vision, to assist 3D Vision in
setting parameters correctly for unusual situations, or to present
application-specific user-accessible controls for 3D Vision
parameters.

This extension provides the ability to explicitly create a surface
with 3D Vision support regardless of application detection.

None

Accepted as an attribute to the <attrib_list> parameter of
CreateWindowSurface and CreatePbufferSurface

    EGL_AUTO_STEREO_NV                0x3136

Additions to section 3.5.1 (Creating On-Screen Rendering Surfaces)

Alter the end of the second to last paragraph:

    Attributes that can be specified in <attrib_list> include
    EGL_RENDER_BUFFER, EGL_VG_COLORSPACE, EGL_VG_ALPHA_FORMAT,
    and EGL_AUTO_STEREO_NV.

Add before the last paragraph of section 3.5.1:
    
    EGL_AUTO_STEREO_NV specifies whether 3D Vision stereo
    (stereo override) should be enabled in the driver. The default
    value of EGL_AUTO_STEREO_NV is zero.
