 Overview
 
-    This extension provides a new color space option, scRGB, for applications to
-    choose from when creating an EGLSurface. The scRGB color space defines a

-    primaries as sRGB, and thus is backward-compatible with sRGB. Refer to
-    the IEC 61966-2-2:2003 standard for details on scRGB color space.
