[PATCH 07/14] doPolyText needs UseAccess to each font, not ReadAccess.

[Jamey Sharp]

In commit 42d6112ec21949a336ee8b34469f2695273ee2d6, Eamon changed
dixChangeGC to require DixUseAccess on any GCFont XID. I think
doPolyText needs to require the same level of access. Otherwise
dixChangeGC could fail when it does the same lookup, which doPolyText
doesn't check for.
