[mcclim-devel] patch for gadget.lisp

This was sent late last year, but it seems the patch got stripped by some helpful agent. I hope this one gets through. Please let me know otherwise. Paul ~~~~~~~~~~~~~~~~~~~~ Here is an improved patch that fixes problems in an earlier post with incorrect cursor position when incremental redisplay was active. It is still required that calls to with-output-as-gadget be wrapped in (updating-output ( ... :cache-value <some-constant>)) to avoid problems if the output-record is ever erased. ~~~~~~~~~~~~~~~
