+ * From the GL_ARB_uniform_buffer_object spec:
+ *
+ *     "For BindBufferRange, <offset> specifies a starting offset into
+ *      the buffer object <buffer>, and <size> specifies the amount of
+ *      data that can be read from the buffer object while used as the
+ *      storage for a uniform block. Both <offset> and <size> are in
+ *      basic machine units. The error INVALID_VALUE is generated if
+ *      the value of <size> is less than or equal to zero, if <offset>
+ *      + <size> is greater than the value of BUFFER_SIZE, or if
+ *      <offset> is not a multiple of the implementation-dependent
+ *      required alignment
+ *      (UNIFORM_BUFFER_OFFSET_ALIGNMENT). BindBufferBase is
+ *      equivalent to calling BindBufferRange with <offset> zero and
+ *      <size> equal to the size of <buffer>."
