Allan Bazinet	ffa7e34602	Rename replot cache	2024-11-10 04:10:38 -08:00
Allan Bazinet	8a60d31933	Kill off Fortran plotsave() routine ... It would be difficult to consider a more unspeakable horror than this; I can’t even think rationally about it. It must be purged, the implementation burned, the ashes scattered, and the ground salted. Dramatically improves replot performance.	2024-11-10 03:56:31 -08:00
