           Summary: WebGL must enforce restrictions even if running on
                    OpenGL ES 2.0
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebGL
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: gman at google.com


The current Webkit implementation of WebGL checks if the underlying platform is OpenGL ES 2.0 and if so stops checking certain WebGL requirements.

The issue is nearly all implementations of OpenGL ES 2.0 support various extensions, for example

GL_OES_texture_npot         makes npot textures work in all situations
GL_OES_element_index_uint   makes it possible to pass GL_INT to drawElement
GL_OES_texture_float        makes it possible to pass GL_FLOAT to texImage2D

WebGL 1.0 is supposed to enforce the restriction these features do not work unless some specific WebGL extension enables the feature.
