Hi Phil,
I don't think (1) is a good idea. It seems like this only effects
somewhat extreme plotting situations? Some of the examples also use
plshade() and they don't seem to be particularly slow.

Hi Hazen, Phil,
If the setting and restoring of the locale takes so much time, then
would it be an option to use this only on the plot functions that might
actually be affected by the locale? I have only glanced at the code and

Github has an interesting feature which lets you browse the code and see
the last commit that touched a particular part of the code. Using that
it looks like saving and restoring the locale was added to the functions
in src/plcore.c by Alan on Sep 7, 2009.

Sorry, I was wrong in my last email - removing the locale calls from
plP_state as well (used to reset the width after a contour draw within
plshade) I ended up with a 2.5 times speed increase

Just checking again if anyone has any knowledge of this?
As far as I can see, plsave_set_locale and plrestore_locale temporarily set
the LC_NUMERIC locale to "C" during calls to the driver. This sets the
decimal delimiter and the thousands separator and how many digits are
between the thousands
