*
* "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>."
