+ *
+ * "All or part of one buffer object's data store may be copied to
+ * the data store of another buffer object by calling
+ *
+ * void CopyBufferSubData(enum readtarget, enum writetarget,
+ * intptr readoffset, intptr writeoffset,
+ * sizeiptr size);
+ *
+ * with readtarget and writetarget each set to one of the targets
+ * ARRAY_BUFFER, COPY_READ_BUFFER, COPY_WRITE_BUFFER,
+ * ELEMENT_ARRAY_BUFFER, PIXEL_PACK_BUFFER, PIXEL_UNPACK_BUFFER,
+ * TEXTURE_BUFFER, TRANSFORM_FEEDBACK_BUFFER, or
+ * UNIFORM_BUFFER. While any of these targets may be used, the
+ * COPY_READ_BUFFER and COPY_WRITE_BUFFER targets are provided
+ * specifically for copies, so that they can be done without
+ * affecting other buffer binding targets that may be in use."
+ *
+ * Specifically, it walks over the available targets and makes sure
+ * that copies work for them.
