* plug-ins/common/flarefx.c: fixed a bug in the new
  preview code and some other small changes

* plug-ins/common/glasstile.c: applied modified version
  of gimp-timecop-200005-5.glasstile which adds a preview
  to the glasstile plug-in.

  While I was on it, I fixed a bug that caused glasstile
  to crash when invoked on a small selection.
