Cache XParseColor results in the X display info structure.
With repeated lookups of foreground and background colors for multiple
faces per frame, we issue a lot of redundant color name lookups to the
X server, waiting every time for the response. On a remote network
with, say, 30ms round-trip time, this can add nearly a full second to
creation of a new frame.
