The driver should be painting the colorkey like it is in all the
other drivers. The client choosing to paint the key should be optional
behavior selected by the client specifically turning off the AUTOPAINT.
Yes, there are problems when the client quits and autopainting is
still left disabled. There's not really a solution for that.
Having the client paint the key itself is a kludge in this API and
is discouraged.
