-
-Name Strings
-
-    CHROMIUM_subscribe_uniform
-
-Version
-
-    Last Modifed Date: October 30, 2014
-
-Dependencies
-
-    OpenGL ES 2.0 is required.
-
-Overview
-
-    Allows clients to subscribe to a set of input uniforms which can
-    be populated within buffers and used to modify uniform variables within
-    their programs.
-
-    Decreases percieved latency for operations performed against these
-    uniforms.
-
-New Tokens
-
-    Accepted by the <target> parameter of glBindValueBufferCHROMIUM,
-    glSubscribeValueCHROMIUM, glPopulateSubscribedValuesCHROMIUM and
-    glUniformValueBufferCHROMIUM
-
-    GL_SUBSCRIBED_VALUES_BUFFER_CHROMIUM                        0x924B
-
-    Accepted by the <subscription> parameter of glSubscribeValueCHROMIUM and
-    glUniformValueBufferCHROMIUM:
-
-    GL_MOUSE_POSITION_CHROMIUM                                  0x924C
-
-New Procedures and Functions
-
-    The command
-
-       void glGenValuebuffersCHROMIUM(GLsizei n, GLuint* buffers)
-
-    Generates value buffer object names.
-    <n> Specifies the number of value buffer object names to be generated.
-    <buffers> Specifies an array in which the generated value buffer object 
-              names are stored.
-
-   The command
-
-      void glDeleteValuebuffersCHROMIUM(GLsizei n, const GLuint* valuebuffers)
-
-   Deletes named value buffer objects.
-   <n> Specifies the number of value buffer objects to be deleted.
-   <buffers> Specifies an array of value buffer objects to be deleted.
-
-   The command
-
-      boolean glIsValuebufferCHROMIUM(GLuint buffer);
-
-   Returns whether an object is a value buffer object.
-   <buffer> Specifies the name of a buffer object.
-
-   The command
-
-      void glBindValuebufferCHROMIUM(GLenum target, GLuint buffer);
-
-   Lets you use a named value buffer object.
-   <target> Specifies the target to which the buffer object is bound.
-   <buffer> Specifies the name of a buffer object.
-
-   The command
-
-      void glSubscribeValueCHROMIUM(GLenum target, GLenum subscription)
-
-   Subscribes the currently bound buffer object to a subscription target.
-   <target> Specifies the target to which the buffer object is bound.
-   <subscription> Specifies the subscription to which the currently bound
-                  buffer object should be subscribed.
-
-   The command
-
-      void glPopulateSubscribedValuesCHROMIUM(GLenum target)
-
-   Populates the currently bound buffer object with all subscription states
-   to which it is subscribed.
-   <target> Specifies the target to which the buffer object is bound.
-
-   The command
- 
-      void glUniformValueBufferCHROMIUM(GLint location, GLenum target,
-                                       GLenum subscription)
-
-   Populates the uniform specified by location within the currently bound
-   program with the value in the currently bound buffer for the subscription
-   target.
-   <location> Specifies the location of the uniform variable to by modified.
-   <target> Specifies the target to which the buffer object is bound.
-   <subscription> Specifies the subscription in the currently bound buffer
-                  whose value should be used to populate the uniform.
