           Summary: Must enable GL_POINT_SPRITE in GraphicsContext3D
                    implementations
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGL
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kbr at google.com

In order to properly support the gl_PointCoord built-in variable in fragment shaders, it is necessary for the various GraphicsContext3D implementations running on desktop GL to enable the GL_POINT_SPRITE capability. This is similar to the earlier requirement to enable the GL_VERTEX_PROGRAM_POINT_SIZE capability.

Note that testing this in WebKit requires ANGLE issue http://code.google.com/p/angleproject/issues/detail?id=35 to be fixed and the version of ANGLE in WebKit to be updated.
