+    CommandBufferEnableCHROMIUM(const GLchar *feature)
+
+    <feature> is a null terminated string of the feature you wish to enable.
+    The requestable feature strings are as follows:
+
+    Note: If used this function MUST be called before any other GL commands
+    except GetString. Calling any other functions first will result in
+    undefined behavior.
+
+    pepper3d_allow_buffers_on_mulitple_targets
+
+    OpenGL ES 2.0 allows a single buffer to be bound to both the ARRAY_BUFFER
+    and ELEMENT_ARRAY_BUFFER bind points. By default Chromium does not allow
+    this.
+
+    This feature is only provided for full OpenGL ES 2.0 compatibility. It is
+    expensive to use and should generally be avoided.
+
+    pepper3d_support_fixed_attribs
+
+    Turns on support for the type GL_FIXED. By default this feature is off in
+    Chromium.
+
+    This feature is only provided for full OpenGL ES 2.0 compatibility. It is
+    expensive to use and should generally be avoided.
