* Remapped color logical operations
*
* With the exception of NVIDIA hardware, which consumes the OpenGL enumerants
* directly, everything wants this mapping of color logical operations.
*
* Fun fact: These values are just the bit-reverse of the low-nibble of the GL
* enumerant values (i.e., `GL_NOOP & 0x0f` is `b0101' while
* \c COLOR_LOGICOP_NOOP is `b1010`).
*
* Fun fact #2: These values are just an encoding of the operation as a table
* of bit values. The result of the logic op is:
*
* result_bit = (logic_op >> (2 * src_bit + dst_bit)) & 1
*
* For the GL enums, the result is:
*
* result_bit = logic_op & (1 << (2 * src_bit + dst_bit))
