[Bf-committers] Temporary "global" storage

Think about it for a couple of seconds though.  Something like "last
button pressed" and "tooltip close time" really are globals.

In what parallel dimension did another button get pressed last?

In what other timeline did a tooltip close?

I get that somebody once told you that global variables are bad but
they are not.  What is bad is exposing the internal workings of
something to another module that does not need to know.  This happens
at all levels of code.

So, don't just make an "extern float last_tooltip_close_time", but
write a sensible interface for it like the other thousands of "global"
functions in Blender.

Even if someday we add dimensional sliding and time travel libraries
to Blender I don't think it will be a big deal to modify the interface
you make :-)
