Set a one-time slowdown on opening standard graphics
This function is mainly for internal use, to work around a bug in macOS Catalina: if base plotting happens too quickly after opening RGL and the first call to quartz, R crashes.
This inserts a delay after the first call to open the
graphics device. The default is
no delay, unless on Catalina with no graphics device
currently open but the quartz device set
as the default, when a 1 second delay will be added.
Use environment variable "RGL_SLOW_DEV = value" to set
a different default delay.
It works by changing the value of options("device"),
so explicit calls to the device will not be affected.
It is called automatically when the rgl package is loaded.

Called for the side effect of adding the delay to the first opening of the graphics device.
