Details:

looking at a bug report on the opengl plotting precision limits, I was running
one of the simple test plots:


x = [1e38:1e38:1e39];
plot(x)


and it triggers an infinite warning loop.  After creating the figure, before
drawing the axes, it hits


warning: opengl_renderer: data values greater than float capacity.  (1) Scale
data, or (2) Use gnuplot


this warning repeats ad infinitum any time you click on the figure window, and
the interpreter is stuck until you escape with a Ctrl-C.  .  Checked in both
CLI and gui with qt toolkit.

I know there are quite a few bug reports related to the general opengl
plotting precision issue, but didn't see this particular issue with the
warning message. please close if duplicate or if should be attached to one of
the other bugs.
