+``Artist.set`` applies artist properties in the order in which they are given
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The change only affects the interaction between the *color*, *edgecolor*,
+*facecolor*, and, for `.Collection`\s, *alpha* properties: the *color* property
+now needs to be passed first in order not to override the other properties.
+This is consistent with e.g. `.Artist.update`, which did not reorder the
+properties passed to it.
