@@ -34,22 +34,26 @@ For a source component `s` and destination component `d`, the logical
 operations are defined as taking the bits of each channel of each component,
 and performing one of the following operations per-channel:
 
-* ``CLEAR``: 0
-* ``NOR``: :math:`\lnot(s \lor d)`
-* ``AND_INVERTED``: :math:`\lnot s \land d`
-* ``COPY_INVERTED``: :math:`\lnot s`
-* ``AND_REVERSE``: :math:`s \land \lnot d`
-* ``INVERT``: :math:`\lnot d`
-* ``XOR``: :math:`s \oplus d`
-* ``NAND``: :math:`\lnot(s \land d)`
-* ``AND``: :math:`s \land d`
-* ``EQUIV``: :math:`\lnot(s \oplus d)`
