* passed to Create then the "default" GL interface is used. If the default is
* also NULL GrContext creation will fail.
*
- * The default interface is specified by calling GrGLSetDefaultInterface. If
- * this function hasn't been called or was last called with NULL then
- * GrGLInitializeDefaultGLInterface will be called to attempt to initialize it.
- * There are several implementations of this function provided. Each builds a
- * GrGLInterface for a specific platform and sets it as the default. There is
- * also an implementation that does nothing. You can link in any of the provided
- * implementations or your own implementation that sets up the GL function
- * pointers for your specific platform.
+ * The default interface is returned by GrGLDefaultInterface. This function's
+ * implementation is platform-specifc. Several have been provided, along with an
+ * implementation that simply returns NULL. It is implementation-specific
+ * whether the same GrGLInterface is returned or whether a new one is created
+ * at each call. Some platforms may not be able to use a single GrGLInterface
+ * because extension function ptrs vary across contexts. Note that GrGLInterface
+ * is ref-counted. So if the same object is returned by multiple calls to
+ * GrGLDefaultInterface, each should bump the ref count.
*
* By defining GR_GL_PER_GL_CALL_IFACE_CALLBACK to 1 the client can specify a
* callback function that will be called prior to each GL function call. See
