            Bug ID: 244252
           Summary: Hide more ANGLE internal formats from WebGL
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGL
          Assignee: webkit-unassigned at lists.webkit.org

Some internal texture formats are either implicitly supported by ANGLE or explicitly enabled by WebKit even if they are not exposed to WebGL apps. Since ANGLE does not know whether a particular API call is done by WebKit itself or by a WebGL application, it cannot reject those extra formats.

Affected entry points and internal formats:
  texImage
    GL_DEPTH_COMPONENT32_OES
    GL_RGBX8_ANGLE
  texStorage
    GL_BGRA4_ANGLEX
    GL_BGR5_A1_ANGLEX
    GL_DEPTH_COMPONENT32_OES
    GL_BGRA8_EXT
    GL_RGBX8_ANGLE
  copyTexImage2D
    GL_BGRA_EXT
    GL_BGRA8_EXT
    GL_RGBX8_ANGLE
