- * A renderbuffer stores colors or depth values or stencil values.
- * A framebuffer object will have a collection of these.
- * Data are read/written to the buffer with a handful of Get/Put functions.
- *
- * Instances of this object are allocated with the Driver's NewRenderbuffer
- * hook.  Drivers will likely wrap this class inside a driver-specific
- * class to simulate inheritance.
+ * Renderbuffers represent drawing surfaces such as color, depth and/or
+ * stencil.  A framebuffer object has a set of renderbuffers.
+ * Drivers will typically derive subclasses of this type.
